Why You Will Love These St. Patrick’s Day Guinness & Baileys Cupcakes
- Unbelievably Rich and Moist Cupcakes: Prepare yourself for a truly decadent experience. Our Guinness chocolate cake base is crafted with a blend of light brown sugar, premium chocolate, and sour cream, which work in harmony to deliver an exceptionally moist, tender crumb and an intensely deep, complex chocolate flavor that forms the perfect foundation for this festive treat.
- Exquisitely Flavored Baileys Buttercream: The Baileys Irish Cream buttercream isn’t just an afterthought – it’s a star! We’ve meticulously balanced the amount of Baileys, ensuring it’s not overpoweringly boozy or too thin to pipe, yet boasts a distinct, luxurious Irish cream flavor that perfectly complements the rich chocolate and caramel. It’s truly “just right,” offering a smooth, creamy texture and a delightful hint of warmth.
- A Harmoniously Balanced Dessert: This isn’t just a cupcake; it’s a symphony of flavors. The robust, slightly bitter notes of the Guinness chocolate cake provide an ideal counterpoint to the luscious, perfectly salted caramel sauce filling. Capping it all off is the sweet, velvety, and subtly boozy Baileys buttercream. Each component has been carefully chosen and proportioned to ensure every bite is a delightful fusion of tastes, making it an irresistible dessert for any occasion, especially St. Patrick’s Day!
Professional Tips for Crafting Perfect St. Patrick’s Day Cupcakes
- Prepare Your Salted Caramel Sauce Ahead of Time: Achieving the perfect salted caramel filling is crucial for these St. Patrick’s Day cupcakes. The consistency needs to be just right – not too thin that it soaks into the cake, nor too thick that it’s difficult to enjoy. Making your caramel sauce in advance allows it to cool and reach that ideal, lava-like flow and thickness, ensuring it holds its shape beautifully within the cupcake and offers a delightful gooey center.
- Embrace Room Temperature Ingredients: This is a golden rule in baking, especially for cupcakes! Using room temperature butter, eggs, and sour cream is vital for achieving the finest textured chocolate cupcakes. Ingredients at the same temperature emulsify more effectively, creating a smoother, more uniform batter. This leads to a lighter, airier, and significantly more tender crumb in your finished cupcakes, making a noticeable difference in quality.
- Ensure Cupcakes are Completely Cooled Before Assembly: Patience is a virtue in baking! It’s absolutely essential that your Guinness chocolate cupcakes are thoroughly cooled before you attempt to fill them with caramel or frost them with Baileys buttercream. If the cupcakes are even slightly warm, the luscious salted caramel will melt and be absorbed by the cake, disappearing entirely, and your beautiful Baileys buttercream will simply slide right off, ruining your presentation and texture.
- Always Sift Your Powdered Sugar: For a truly silky-smooth Baileys buttercream, do not skip this step! Powdered sugar, also known as confectioner’s sugar, tends to clump over time due to moisture. Simply mixing it with butter often isn’t enough to break down these stubborn lumps. Sifting the sugar is a quick, inexpensive step that guarantees an incredibly smooth, lump-free buttercream, providing that professional finish your St. Patrick’s Day treats deserve.
Essential Ingredients & Smart Substitutions for Your St. Patrick’s Day Cupcakes
- Dutch-Processed Cocoa Powder: For that characteristic deep, dark chocolate flavor and rich color, Dutch-processed cocoa powder is highly recommended. It has been treated with an alkaline solution, neutralizing its acidity, which results in a smoother, less bitter taste compared to natural cocoa. While natural cocoa powder can be used, expect a slightly lighter color and a tangier chocolate flavor.
- Bittersweet Chocolate: I opt for bittersweet chocolate to provide a sophisticated depth and to perfectly balance the sweetness in the cake and subsequent caramel and buttercream layers. If bittersweet isn’t available, dark chocolate with a cocoa percentage of 60% or higher is a good substitute to prevent the cupcakes from becoming overly sweet.
- Espresso Powder: This secret ingredient, espresso powder, doesn’t make your cupcakes taste like coffee; instead, it remarkably intensifies and deepens the flavors of both the chocolate and the Guinness within the cake, adding a subtle complexity that will have everyone asking for your secret.
- Guinness Beer: The star of our chocolate cake base! This recipe calls for just ¾ cup of Guinness. Feel free to open a fresh can or bottle, measure out what you need, and then enjoy the remainder! If you’re feeling extra ambitious, the rest of the Guinness can be wonderfully utilized to create another batch of our rich Guinness chocolate cake or even a savory stew.
- Sour Cream: This ingredient is essential for creating an incredibly moist and tender crumb. Sour cream provides just the right balance of moisture to hydrate the flour and fat to keep gluten development in check. Its acidity also reacts with the baking soda, contributing to a perfect rise and a wonderfully fluffy texture. Full-fat Greek yogurt, like Fage 5% yogurt, can be used as a close substitute for similar results.
- All-Purpose Flour: The backbone of our cake structure, all-purpose flour provides the ideal gluten content needed to create a tender, yet structurally sound, chocolate cake that holds up well to its fillings and frosting.
- Kosher Salt: A fundamental flavor enhancer in both sweet and savory recipes, Kosher salt balances the sweetness and brings out the richer notes of chocolate and caramel.
- Baking Soda: This leavening agent works in conjunction with the acidic sour cream and cocoa powder to give our cupcakes their beautiful rise and light texture.
- Unsalted Butter: For both the cake and especially the buttercream, unsalted butter is key. In frostings, it provides crucial stability and rich flavor. When chilled, butter firms up, helping the buttercream hold its shape for elegant piping and structural integrity on your cupcakes.
- Light Brown Sugar: Beyond just sweetness, light brown sugar introduces a delightful hint of molasses flavor and additional moisture, contributing to the cake’s softness and moistness. Dark brown sugar can be substituted for a more pronounced molasses flavor, or granulated sugar in a pinch, though the latter will result in a slightly less moist cake.
- Vanilla Extract: A classic flavor enhancer, vanilla extract rounds out the complex flavors of chocolate, Guinness, and caramel, adding a warm, aromatic note.
- Eggs: Serving multiple vital roles, whole eggs contribute fat for richness, moisture for tenderness, and act as a leavening agent. They are also crucial emulsifiers, helping to bind the batter together and create that desirable tender, cohesive texture.
- Confectioner’s Sugar: The foundation of our American-style Baileys buttercream. Confectioner’s sugar, finely ground into a powder, dissolves effortlessly into the butter without needing heat, ensuring a smooth, silky, and stable buttercream with ease.
- Baileys Irish Cream: The luxurious heart of our buttercream! The Baileys in this frosting is not cooked, meaning its distinct alcoholic flavor remains, adding a sophisticated kick to your dessert. This is similar to how it works in our popular Baileys Irish Coffee Caramel Brownies recipe. For a non-alcoholic alternative, you can substitute heavy cream and a touch of vanilla extract to achieve a similar consistency and delightful flavor.
- Salted Caramel Sauce: The delectable filling for these cupcakes. You have the flexibility to use either my highly acclaimed homemade salted caramel sauce or a good quality store-bought version. If you choose to make it from scratch, I highly recommend doubling the batch! You’ll then have extra to enjoy with other treats, such as these tempting chocolate caramel cupcakes or our utterly addicting carmelitas!

Creative Variations for Your St. Patrick’s Day Cupcakes
While the classic Guinness, salted caramel, and Baileys combination is undeniably perfect, these cupcakes offer a fantastic canvas for your creativity! Here are some delightful variations to make them uniquely yours:
- Experiment with Different Frostings: While our Baileys buttercream is divine, feel free to switch things up! You could top these rich chocolate cupcakes with our luxurious caramel Swiss meringue buttercream for an incredibly smooth and less sweet option. For a tangy twist that complements the rich chocolate, our cream cheese buttercream frosting is a fantastic choice. If you’re a true chocolate lover, consider going double chocolate with our easy and decadent chocolate buttercream frosting recipe. And for those who prefer to keep the boozy theme going, our bourbon cream cheese buttercream from the best red velvet cake recipe offers another delightful alcoholic kick.
- Explore Alternative Fillings: The salted caramel is a dream, but you can certainly customize the center of your cupcakes! Try a rich salted maple caramel sauce for a seasonal twist. For a fruity burst, a vibrant cherry preserve or a berry compote would be lovely. Or, if you want to elevate the Irish cream flavor, prepare our smooth vanilla bean pastry cream recipe and infuse it with an extra splash of Baileys for an even more pronounced boozy custard filling.
- Embrace Fun & Festive Decorations: St. Patrick’s Day is all about celebration, so don’t shy away from playful decorations! Classic shamrock sprinkles are always a must-have for an instant festive touch. For a whimsical “rainbow in the clouds” look, you can add colorful rainbow belt candies across the top of the frosting, perhaps nestled amongst mini marshmallows for a puffy cloud effect. Edible gold dust or sprinkles can also add a touch of leprechaun magic!
Step-by-Step Guide: How to Make Irresistible St. Patrick’s Day Cupcakes
Follow these detailed, easy-to-understand instructions to craft your very own festive and incredibly delicious St. Patrick’s Day cupcakes. For precise measurements and a full ingredient list, please refer to the comprehensive recipe card located further down this page.
Crafting the Rich Guinness Chocolate Cupcakes:
Step 1: Begin by preheating your oven to 325°F (160°C). This ensures a consistent baking temperature from the moment your batter enters the oven. Line 24 standard cupcake tins with paper liners, preparing them for your delicious batter.
Step 2: In a generously sized bowl, combine the Dutch-processed cocoa powder, finely chopped bittersweet chocolate, and the espresso powder. This blend creates the profound chocolate base.
Step 3: Gently heat the Guinness beer in a small saucepan until it just begins to simmer, but not boil vigorously. Carefully pour this hot Guinness over the chocolate mixture you prepared in the large bowl. Allow it to sit undisturbed for at least a minute, letting the heat from the stout melt the chocolate. Then, whisk thoroughly until the mixture is completely smooth and all the chocolate has melted. Set this rich chocolate-Guinness mixture aside to cool down to room temperature.
Chef’s Tip for Melting Chocolate: Ensure your bittersweet chocolate is chopped into small, uniform pieces. This significantly aids in quicker and more even melting when the hot Guinness is poured over it. Allowing it to rest for a minute before whisking ensures maximum heat transfer for a perfectly smooth mixture.
Step 4: While your chocolate-Guinness mixture is cooling, take a separate medium bowl. Whisk together the all-purpose flour, Kosher salt, and baking soda. This ensures the leavening and seasoning are evenly distributed throughout the dry ingredients.
Step 5: Once the chocolate mixture has cooled to room temperature, whisk in the room temperature sour cream until it’s fully incorporated and the mixture is smooth and creamy. The sour cream will add an incredible richness and moisture to the cake.
Step 6: In the bowl of a stand mixer fitted with the paddle attachment (or using an electric hand mixer), beat the room temperature unsalted butter, light brown sugar, and vanilla extract together at medium speed. Continue mixing until the mixture becomes notably pale in color and beautifully fluffy in texture, indicating that air has been incorporated.
Step 7: Add the eggs to the butter and sugar mixture, one at a time. Beat each egg in until it is just incorporated before adding the next. Make sure to scrape down the sides of the bowl with a spatula after each addition to ensure everything is evenly mixed.
Note on Batter Texture: Don’t be alarmed if, after adding the eggs, the batter appears slightly separated or curdled. This is a common occurrence due to the ratio of fat from the butter and the moisture from the eggs, and it will happen regardless of how perfect your room temperature ingredients are. It will come together beautifully once the dry ingredients are added.
Step 8: Reduce the mixer speed to its lowest setting. Begin adding the flour mixture in three separate additions, alternating with the chocolate-Guinness-sour cream mixture. Start and end with the flour mixture, mixing just until combined after each addition. Be careful not to overmix, as this can lead to tough cupcakes.
Step 9: Evenly scoop the prepared batter into each of the lined cupcake tins, filling them approximately two-thirds full. Bake for about 20-30 minutes, or until a wooden toothpick or cake tester inserted into the center of a cupcake comes out with just a few moist crumbs attached. Avoid over-baking. Allow the cupcakes to cool in the pan for 5 minutes before carefully transferring them to a wire rack to cool completely.
Preparing the Velvety Baileys Irish Cream Buttercream:
Step 10: Ensure your baked cupcakes are completely cooled before starting the buttercream. In a stand mixer (or with an electric hand mixer), beat the room temperature butter on high speed until it becomes incredibly light, fluffy, and noticeably paler in color. This process is crucial for a light and airy buttercream.
Speedy Butter Softening Trick: If you’re short on time and your butter isn’t at perfect room temperature, cube it and place it in your stand mixer bowl with the paddle attachment. Mix on medium speed while gently warming the outside of the bowl with a kitchen torch. Keep the torch moving constantly to soften the butter evenly without melting any part of it.
Step 11: With the mixer on low speed, gradually add the sifted confectioner’s sugar to the beaten butter. Once all the sugar is added, increase the speed to medium and continue beating until the mixture is well combined and smooth.
Step 12: Now, add the Baileys Irish Cream, one tablespoon at a time. Beat thoroughly after each addition, and remember to scrape down the sides and bottom of the bowl frequently. Continue whipping until the buttercream is light, fluffy, and smooth. If your butter wasn’t perfectly softened initially, this step might take a little longer to achieve the desired consistency.
Step 13: Using a rubber spatula, carefully transfer the finished Baileys buttercream into a piping bag fitted with your chosen piping tip (a Wilton 1M or 2D works beautifully for a classic swirl). Press the buttercream down towards the tip, ensuring there are no air bubbles, and twist the top opening of the pastry bag firmly to prevent any delicious frosting from escaping.
Assembling Your Festive St. Patrick’s Day Cupcakes:
Step 14: Once the cupcakes are completely cool, it’s time for the delicious filling! Using a small knife, a specialized cupcake corer, or even a small round cookie cutter, carefully remove a cone-shaped center from each cupcake. Don’t discard the removed cake pieces – you can snack on them or crumble them for another dessert!
Step 15: Generously fill the cored center of each cupcake with your prepared salted caramel sauce. Remember, the caramel should have a thick, “cooling lava” consistency. If it’s too warm and runny, it will simply absorb into the cake, so ensure it has cooled sufficiently.
Step 16: Finally, pipe your smooth Baileys buttercream onto each cupcake using your prepared piping bag. If you don’t have a piping bag, simply spread the frosting evenly with an offset spatula. For an extra festive touch, sprinkle with vibrant green sanding sugar or other St. Patrick’s Day themed sprinkles! These delightful cupcakes are best enjoyed fresh but can be stored at room temperature for up to 3 days in an airtight container.
Chef Lindsey’s Expert Baking Tip for Batch Baking
For those ambitious bakers planning to make a double or triple batch of these delicious St. Patrick’s Day cupcakes, a crucial tip is to ensure you have enough muffin tins readily available. The leavening power of baking soda in this recipe provides one primary, effective rise. If your cupcake batter is allowed to sit for an extended period before being baked – perhaps while you wait for a single muffin tin to finish baking and cool – the chemical reaction that creates that perfect rise will diminish. The result? You might end up with denser, flatter cupcakes rather than the light and airy ones this recipe is designed to produce. Plan ahead with enough tins to bake all your batter promptly for the best results!
Frequently Asked Questions About St. Patrick’s Day Cupcakes
To keep your frosted Guinness chocolate cupcakes tasting their best, store them in an airtight container in the refrigerator for up to one week. For longer storage, they can be frozen for up to two months. If you prefer to bake ahead, unfrosted cupcakes can be tightly wrapped in plastic wrap and stored at room temperature, refrigerated, or frozen. For optimal flavor and moisture, however, these cupcakes are truly at their peak when filled with salted caramel and frosted with Baileys buttercream on the day they are to be served. If you absolutely need to prepare them in advance, freezing the unfrosted cupcakes is your best option, then thaw and decorate closer to your event.
A runny buttercream is usually a sign that too much liquid, in this case, Baileys Irish Cream, has been added. Don’t worry, it’s an easy fix! Simply add more sifted confectioner’s sugar, a quarter cup at a time, beating well after each addition, until the buttercream reaches your desired thick, pipeable consistency. Remember to add liquids sparingly when making frosting to avoid this issue.
Absolutely! These St. Patrick’s Day cupcakes make a fantastic dessert for any celebration, but they pair wonderfully with hearty savory dishes. Consider serving our rich and comforting Dutch oven beef stew or a flavorful rosemary lamb stew to complete your Irish-themed meal. For more festive sweet options, explore making green-tinted sugar cookies or even a traditional Irish coffee. The possibilities for a delicious St. Patrick’s Day feast are endless!
While Guinness is recommended for its distinct dark, malty flavor that wonderfully complements the chocolate, you certainly can experiment with other beers. I would strongly suggest sticking to another stout or a dark ale, as these will offer a similar flavor profile and depth. Avoid using lighter beers, IPAs, or pale ales, as their hoppy or crisp notes can introduce an unwanted bitterness or an odd flavor to the chocolate cake, detracting from the intended rich and smooth taste.

Salted Caramel Filling
Instructions
Make the cupcakes:
-
Preheat the oven to 325°F and line 24 cupcake tins with liners.
-
Combine the cocoa powder, chocolate, and espresso powder in a large bowl.
-
Bring the Guinness to barely boiling in a small saucepan. Pour the hot Guinness over the chocolate mixture and whisk until completely melted and smooth. Set aside to cool to room temperature.
-
While the chocolate mixture is cooling, combine flour, salt, and baking soda together in a medium bowl and whisk.
-
Whisk the sour cream into the chocolate mixture when it is cool.
-
In a bowl of a stand mixer or with an electric mixer, beat the butter, sugar, and vanilla together at medium speed until pale and fluffy.
-
Beat in the eggs, one at a time, until incorporated. Wiping down the sides of the bowl after each addition.
-
Reduce the mixer speed to low and add the flour mixture in three additions. Alternate between the flour and chocolate mixture, beginning and ending with flour.
-
Scoop the batter into the cupcake liners. Bake until a toothpick or cake tester comes out with some crumbs still attached, about 20-30 minutes. Cool in the cupcake pan for 5 minutes before cooling on a wire rack.
Make the buttercream:
-
Let the cupcakes cool completely. Beat the butter until light and fluffy on high speed with an electric mixer or in the stand mixer.
-
Slowly add the powdered sugar. Continue to beat until well combined.
-
Add the Baileys a tablespoon at a time, beating and scraping the bowl down between each addition. Whip until light and fluffy. If your butter was not completely softened, this will take longer.
-
Use a rubber spatula to put the frosting in a piping bag fitted with a piping tip of your choice. Press the buttercream all the way to the bottom of the bag, making sure there are no air bubbles. Twist the top opening of the pastry bag to ensure you don’t lose any of the deliciousness.
Assemble the cupcakes:
-
Remove the center of the cupcakes using a knife, a cupcake corer, or any other small, round object of your imagination.
-
Fill the center with the salted caramel sauce. It should be thick, like cooling lava. If it is too warm and runny, then it will just soak into your cake.
-
Pipe (or spread) the frosting onto each cupcake. I use a Wilton 2D piping tip. Sprinkle with green sanding sugar if desired! Store at room temperature for up to 3 days.
Notes
Presentation Tips – For the freshest taste and most appealing presentation, these cupcakes are best filled and frosted on the same day they are intended to be served.
Creative Variations – Make these cupcakes even more festive by adding a few drops of green gel food coloring to the Baileys buttercream! Gel coloring is recommended as it won’t thin out the frosting. Finish with a flourish of gold sprinkles or playful rainbow candy for an extra touch of St. Patrick’s Day magic!
Flavor Enhancement Tips – If you have a choice, opt for draught Guinness over stout Guinness. Draught is infused with nitrogen, lending a smoother, softer flavor profile to your cake, whereas stout uses carbon dioxide, which can result in a crisper and slightly more bitter taste.
Storage Guidelines – To preserve their deliciousness, store frosted cupcakes in an airtight container in the refrigerator for up to a week, or freeze them for up to two months. Unfrosted cupcakes can be wrapped tightly in plastic wrap and stored at room temperature, refrigerated, or frozen for flexibility.
