Why You’ll Love These Guinness Chocolate Cupcakes

These cupcakes offer more than just good looks. The stout adds depth without overwhelming the chocolate, and the Irish cream frosting is the creamy crown on top. They’re perfect for St. Patrick’s Day parties, birthdays, or when you just want to impress with a bakery-quality dessert made right in your kitchen. And yes, you can absolutely taste the difference that Guinness makes — it enhances the chocolate in a way that water or milk simply can’t.

What Kind of Guinness Should I Use?

Stick with the classic: Guinness Draught. It’s smooth, easy to find, and has just the right amount of roasted bitterness to enrich the chocolate flavor. You don’t need any fancy variations or extra stouts. Canned or bottled Guinness Draught works great. If you’re avoiding alcohol entirely, you could substitute with a dark brewed coffee, but you’ll lose some of that unique malty charm.

How To Make the Guinness Chocolate Cupcakes

Step 1: Prepare the Oven and Pan

Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.

Step 2: Simmer the Guinness and Butter

In a saucepan over medium heat, combine the Guinness and butter. Let the butter melt completely and then whisk in the cocoa powder until smooth. Let it cool slightly.

Step 3: Mix Dry Ingredients

In a large bowl, whisk together the flour, sugar, baking soda, and salt.

Step 4: Combine Wet Ingredients

In a separate bowl, mix together the sour cream, egg, and vanilla extract. Slowly stir in the slightly cooled Guinness mixture.

Step 5: Make the Batter

Add the wet ingredients to the dry ingredients and mix until just combined. Do not overmix.

Step 6: Bake

Divide the batter evenly between the cupcake liners. Bake for 17–20 minutes or until a toothpick comes out clean. Let them cool completely.

Step 7: Make the Frosting

In a large bowl, beat the butter until creamy. Slowly add powdered sugar, then mix in the Irish cream. Beat until light and fluffy.

Step 8: Frost the Cupcakes

Once cupcakes are completely cool, pipe or spread the frosting on top. Decorate with chocolate shavings or cocoa powder if desired.

How to Serve and Store These Cupcakes

These Guinness Chocolate Cupcakes make a perfect treat for up to 12 people. Serve them at room temperature for the best texture and flavor. If you’re prepping ahead, store the frosted cupcakes in an airtight container in the fridge for up to 4 days. Let them sit out for 15–20 minutes before serving so the frosting softens. You can also freeze unfrosted cupcakes for up to 2 months. Just thaw, frost, and enjoy.

A scoop of creamy vanilla makes this dessert even more indulgent.

Fresh Berries

Frequently Asked Questions

Can I make these cupcakes alcohol-free?

Yes! You can substitute the Guinness with brewed dark coffee and the Irish cream liqueur with milk and a touch of vanilla. You’ll miss a bit of that malty depth, but they’ll still taste great.

Do these cupcakes taste like beer?

Not exactly. The Guinness enhances the chocolate flavor but doesn’t overpower it. It’s more of a background note that makes the cupcakes richer and more complex.

Can I use a different type of beer?

You can, but results will vary. A dark stout or porter works best. Avoid IPAs or pale ales as their bitterness may throw off the flavor.

How can I make them ahead of time?

Bake the cupcakes a day in advance and store them in an airtight container. Frost them the day you plan to serve. You can also freeze the cupcakes (without frosting) and defrost them when needed.

Can I make this into a cake instead of cupcakes?

Yes! You can bake the batter in an 8-inch round cake pan. Adjust the baking time to about 30–35 minutes. For more on adapting baked goods, check out our cake baking tips.
