Jump straight to the recipe!
These Guinness chocolate cupcakes do not have a strong beer flavour to them. The beer brings out the chocolate flavour much as adding coffee to a chocolate cake does. You are left with only a hint of the beer flavor in both the cake and frosting.
The chocolate cupcake is moist and fluffy with a big chocolate flavour. The buttercream has both cocoa powder and melted chocolate in it which makes it very chocolate-y. If you like chocolate on chocolate cupcakes, this one is for you!
Ingredients
- unsalted butter
- granulated sugar
- large eggs
- vanilla extract
- Guinness beer - or any other stout beer.
- cocoa powder
- all purpose flour
- baking powder
- salt
- shortening - I used a combination of shortening and butter in the frosting. You can use all butter if you prefer.
- semi sweet chocolate - use good quality baking chocolate. Do not use chocolate chips.
- powdered sugar
How to make these cupcakes
Mix all the dry ingredients together and then set that aside. In a separate bowl, stir the melted butter and the sugar together. Mix in the eggs, one at a time, mixing well after each addition. Stir in the vanilla and Guinness.
Stir the dry ingredients into the wet. Fill each cupcake liner ¾ full and bake for 15-18 minutes or until a toothpick comes out clean.
Chocolate Buttercream
This buttercream is super chocolate-y! If you don't particularly like the butter flavour in buttercream frosting, you will love this! Both cocoa powder and melted chocolate is in this frosting. All you taste is a creamy, velvety, chocolate frosting. It is delicious!
I also used a combination of shortening and butter in this frosting. You can sub the shortening out and use full butter if you prefer. I find that the shortening lessens the strong butter flavour, and also makes the frosting super pipeable.
Start by creaming the shortening and butter together until it is smooth and lightened in colour. Stir in the melted chocolate and cocoa powder. Mix in half the powdered sugar and 2 tablespoons of beer. Mix in the remaining powdered sugar and the salt, and then the rest of the beer until the buttercream is the right consistency.
Tips
- If you want to use all butter for the buttercream, replace the ¼ cup of shortening with ¼ cup of butter. You will be using a total of 1 cup butter in the buttercream recipe.
- Make sure your butter and shortening is at room temperature. I leave them out at room temperature for at least an hour before making the buttercream.
- You can use any kind of stout beer. Just make sure that it is a stout. All other kinds of beer would not work well at all in this recipe. The stout enhances the chocolate flavour.
- I piped the buttercream onto the cupcakes with a Wilton 1M tip (my favorite!)
