Like my Guinness Cake Pops, these Guinness Chocolate Cupcakes use real Guinness to create a decadent chocolate cake which we are making even more decadent with a swirl of Bailey’s Buttercream.
Guinness Chocolate Cupcakes with Irish Buttercream Recipe
I’m not a huge fan of beer, but stout is a whole other story! I had my first one while visiting family in England when I was a teenager – for breakfast!
(The Irish’s answer to brunch mimosas?)
Every since, I’ve been a devout Guinness fan – although I’ve also found and enjoy Young’s Double Chocolate Stout, which would also work well in this recipe.
A fresh pulled pint is definitely the best way to enjoy it, but I would have to say this recipe comes a close second.
The stout cooks down to help create a moist, rich and flavourful chocolate cake with just the faintest taste of Guinness. Instead of trying to take centre stage, the Guinness’s job in this recipe is to really develop the flavour of the chocolate – which is does beautifully.
Now, you could call it a day and top these chocolate cupcakes with a vanilla or mint buttercream, but I figure why stop there? A delicious batch of from-scratch buttercream frosting made with your favourite flavour of Bailey’s is the ultimate way to finish off these beauties.
While these Guinness Chocolate Cupcakes are perfect for St. Patrick’s Day, they really are the ultimate chocolate cupcake for a grown-up chocolate lover. I make them every year for my brother’s birthday – and bonus, since most of the alcohol cooks away, you can totally get away with having one of these for breakfast – weekend or not!

How to Make Guinness Cupcakes
Preheat oven to 350F and line 2 cupcake trays with liners.
Combine the stout, butter and cocoa powder over medium heat until smooth. Remove and cool.
In a large bowl, stir together the flour, sugar, baking soda and salt. Set aside.
In a second bowl, combine the eggs and sour cream. Slowly add the stout mixture until fully combined.
Add half of the flour mixture, mix thoroughly, then the rest and combine.
Portion into cupcake liners and bake for 15-17 minutes.
Make the frosting by combining the icing sugar, butter, and half of the Bailey’s.
Mix for two minutes, then add more Bailey’s as needed to achieve desired texture. (Add more frosting to stiffen if you add too much Bailey’s.)
Scoop the frosting into a piping bag fit with your desired tip.
Once the cupcakes have cooled, swirl the frosting onto the cupcakes as shown in the video above – starting in the middle, swirl out to the outside, and then back in, piling up.
