What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and a satisfying, moist texture without the fuss. Most are pantry staples, but a few special touches make all the difference.

• For the Cupcakes:
  • 1 cup (240 ml) Guinness stout (the classic Irish beer that adds depth and moisture)
  • ¾ cup (170 g) unsalted butter, cut into pieces (adds richness and tenderness)
  • ¾ cup (75 g) unsweetened cocoa powder (I recommend Valrhona for best flavor)
  • 1 ½ cups (300 g) granulated sugar
  • 2 large eggs, room temperature
  • 1 cup (240 ml) sour cream (adds tang and moistness)
  • 2 cups (250 g) all-purpose flour
  • 2 ½ teaspoons baking soda (helps the cupcakes rise perfectly)
  • ½ teaspoon salt
• For the Bailey’s Frosting:
  • 1 ½ cups (340 g) unsalted butter, softened (room temperature is key)
  • 4 cups (480 g) powdered sugar, sifted
  • ¼ cup (60 ml) Bailey’s Irish Cream (adds that signature flavor)
  • 1 teaspoon vanilla extract
  • Pinch of salt (balances the sweetness)

If you’re looking for a dairy-free option, you can swap the butter for a plant-based alternative and use coconut yogurt instead of sour cream. For a gluten-free twist, almond flour can be substituted but expect a slightly different texture — still delicious!

Pro tip: I always use room temperature eggs and butter to get the batter smooth and silky. Also, look for a Guinness stout with a fresh taste (avoid expired cans) to get the best flavor punch in your cupcakes.

Equipment Needed

• Standard 12-cup muffin tin (non-stick preferred, but paper liners work great too)
• Mixing bowls (at least two: one large for dry ingredients, one for wet)
• Electric mixer or sturdy hand whisk (makes the frosting silky smooth)
• Measuring cups and spoons (for accuracy in baking)
• Spatula (for folding batter gently and scraping bowls)
• Cooling rack (lets cupcakes cool evenly without sogginess)

If you don’t have an electric mixer, no worries — a strong arm and a whisk will do, though it takes a little longer. For budget-friendly options, silicone spatulas and basic metal muffin tins work beautifully and last forever with good care.

Pro tip: Keep your butter soft but not melted for the best frosting texture, and don’t skip the cooling rack — cupcakes cool faster and keep their crumb from getting dense.

Preparation Method

1. Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners or lightly grease it. This step takes about 10 minutes and sets the stage for perfect cupcakes.
2. Warm the Guinness and butter: In a medium saucepan, combine the Guinness stout and unsalted butter. Heat over medium heat until the butter melts and the mixture is just simmering. Remove from heat and whisk in the cocoa powder until smooth. This creates a rich, chocolatey base. (About 5 minutes)
3. Mix dry ingredients: In a large bowl, sift together the flour, baking soda, salt, and sugar. Sifting helps avoid lumps and ensures an even rise. (2 minutes)
4. Combine wet ingredients: In another bowl, whisk the eggs and sour cream until smooth. This adds moisture and tenderness to the cupcakes. (2 minutes)
5. Bring it all together: Slowly pour the warm Guinness and cocoa mixture into the wet ingredients, whisking continuously to prevent cooking the eggs. Then fold this wet mixture into the dry ingredients using a spatula until just combined. Be careful not to overmix! The batter should be smooth but a little thick. (About 5 minutes)
6. Fill the cupcake liners: Spoon the batter evenly into the prepared muffin tin, filling each about ⅔ full. This helps them rise nicely without spilling over. (5 minutes)
7. Bake: Place the tin in the oven and bake for 18–22 minutes. Check doneness by inserting a toothpick into the center—if it comes out clean or with a few moist crumbs, they’re ready. (18-22 minutes)
8. Cool completely: Remove cupcakes from the oven and transfer to a cooling rack. Let them cool fully before frosting, usually 30–40 minutes. Patience here keeps your frosting from melting! (30-40 minutes)
9. Make the Bailey’s frosting: Beat the softened butter in a large bowl on medium speed until creamy, about 3 minutes. Gradually add powdered sugar, beating on low until incorporated. Add the Bailey’s Irish Cream, vanilla extract, and salt. Increase speed to medium-high and beat for 2–3 minutes until light and fluffy. (10 minutes)
10. Frost the cupcakes: Use a piping bag or a simple knife to frost each cupcake generously. For a fun touch, sprinkle a pinch of cocoa powder or chocolate shavings on top. (10 minutes)

Common hiccup? If your batter looks grainy after mixing, it’s usually because the butter wasn’t fully melted or the eggs were too cold. Let those ingredients come to room temp next time.

Trust me, these steps are worth the extra care — the flavors and texture turn out just right every time!

Cooking Tips & Techniques

When baking these Perfect Guinness Chocolate Cupcakes with Bailey’s Frosting, a few lessons learned the hard way will save you some headache:

• Don’t skip sifting: Cocoa powder and flour can clump easily. Sifting avoids lumpy batter and gives a lighter crumb.
• Use room temperature ingredients: Cold eggs or butter can cause curdling or uneven batter texture. Let them warm up for about 30 minutes on the counter.
• Be gentle when mixing: Overmixing develops gluten and makes cupcakes tough. Fold dry and wet ingredients just until combined.
• Check your oven temperature: Oven temps vary — if cupcakes are browning too fast, lower the temp by 10 degrees Fahrenheit and bake a bit longer.
• Let cupcakes cool fully before frosting: Frosting melting is a rookie mistake. The cupcakes must be cool to keep that Bailey’s frosting looking pretty and tasting perfect.
• Beat your frosting well: The secret to that dreamy, almost cloud-like frosting texture is beating butter and sugar long enough to incorporate air.
• Multitasking tip: While cupcakes bake, prep your frosting ingredients and clean your prep area. It’s all about kitchen efficiency!

Honestly, these tweaks make all the difference between good cupcakes and ones that people beg you for the recipe.

Variations & Adaptations

Let’s talk about how you can make these Perfect Guinness Chocolate Cupcakes with Bailey’s Frosting your own:

• Vegan version: Replace eggs with flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg) and use vegan butter and non-dairy sour cream. For Bailey’s, swap with an Irish cream-flavored coconut cream or omit and add vanilla.
• Seasonal flair: Add a teaspoon of orange zest or a splash of coffee to the batter for a festive twist. In summer, swap the Bailey’s frosting for a light whipped cream topping with fresh berries.
• Extra chocolatey: Fold in ½ cup (90 g) mini dark chocolate chips into the batter before baking. Or swirl melted chocolate into the frosting for a marbled effect.
• Nutty delight: Add chopped toasted pecans or walnuts on top of the frosting for a crunchy contrast.
• Alternative alcohols: If Bailey’s isn’t your thing, try a coffee liqueur or amaretto in the frosting for a different but equally delicious flair.

I once made a batch with espresso powder added to the batter and swapped Bailey’s for hazelnut liqueur — my family was so impressed, they asked me to make it again immediately!

Serving & Storage Suggestions

These cupcakes are best served at room temperature to let those flavors shine, but honestly, they’re pretty fantastic chilled on a warm day too. For presentation, I love placing them on a rustic wooden platter with a dusting of cocoa powder or a few chocolate curls for that wow factor.

Pair them with a glass of cold milk, a cup of strong black coffee, or even an Irish coffee for a boozy treat that doubles the indulgence.

To store, keep cupcakes in an airtight container in the refrigerator if you’re frosting them with Bailey’s cream (due to the dairy and alcohol). They’ll stay fresh for up to 4 days. You can also freeze unfrosted cupcakes wrapped tightly in plastic wrap and foil for up to 2 months — just thaw and frost when ready to serve.

Reheat refrigerated cupcakes for 10 seconds in the microwave to soften them slightly before eating, but be careful not to melt the frosting.

Flavors deepen after a day or two, so if you can wait, they taste even better the next day — patience rewarded every time!
