Decadent chocolate cupcakes infused with Guinness and topped with a luscious Irish cream frosting. A must for St. Patrick’s Day, or any day for the beer lover in your life!
Friends, how do you feel about baking with beer? While the idea of a Guinness cupcake really speaks to me around St. Patrick’s Day, there’s no reason not to bake these year-round. Even putting aside the plain fun of baking with Guinness, they are, put simply, among the best chocolate cupcakes I’ve had.
Think rich chocolate flavor, complemented perfectly by the slight bitterness of stout beer and a warm hint of cinnamon. Butter adds more flavor still, while sour cream in the batter ensures each cupcake is moist and light.
And the frosting. Have mercy! Your basic sweet cream cheese frosting gets a lot more interesting when you add a generous glug of Bailey’s Irish cream!
Chocolate Guinness cupcakes recipe notes
This recipe yields 18 cupcakes, and can be ready to go in just about an hour, start to finish. Not too shabby! Here’s what you’ll need for the cupcakes:
- Butter.
- Eggs.
- Sour cream or creme fraiche. (Greek yogurt works well, also.)
- Guinness or another stout beer – I recommend the regular draught stout, it’s bitter but not overly so.
- Vanilla extract.
- Dutch-process cocoa powder. This adds a wonderful depth of flavor and is great in lots of chocolate baked goods. If you’re worried about using the rest of the package, here is a collection of recipes using Dutch cocoa powder.
- Regular granulated sugar.
- All-purpose flour.
- Baking soda.
- Cinnamon.
Pro tip: you’ll only use 6 ounces of Guinness, probably about half of your bottle or can, so… bottom’s up! 🙂
How to make Irish cream frosting
The sweetness of Irish cream liqueur pairs perfectly with a cream cheese frosting, and together they make the dreamiest cloud to set off these rich chocolate cakes.
In fact, now that I look at it, it’s almost as if the cupcake is the beer and the frosting is the foam. Pinky swear that was not intentional. But I’m guessing it might be fun for the true beer aficionados out there! 😉
As written below, this recipe makes enough for a medium amount of Irish cream-flavored frosting to cover a batch of 18 cupcakes. If you want more or less, it’s easy to scale!
I frosted these cupcakes using a Wilton 1M open star tip – my go-to! (affiliate link)

- To make the frosting, using an electric mixer, cream together the butter and cream cheese. Gradually add the powdered sugar, mixing until light and fluffy, then add the salt and vanilla. Beat well to combine, then add Irish cream, and beat again until frosting is a smooth consistency for piping. Frost cupcakes as desired.
