You will need the following ingredients for the cake:
1 cup of Guinness Extra Stout
1 tablespoon of vanilla extract
3/4 cup of unsalted butter
3/4 of unsweetened cocoa powder
1 1/2 cups of granulated sugar
1 1/4 cups of all purpose flour
1 teaspoon of baking soda
You will need the following ingredients for the frosting:
2 cups of unsalted butter - softened
7 cups of powdered sugar
5-6 tablespoons of Baileys Irish Cream
You will need the following supplies:
rubber spatula (optional)
2 eight inch cake pans
Stand mixer (a hand mixer may also work)
Step 1: Make the Chocolate Beer Sauce
In a sauce pan combine 3/4 cup of butter, cocoa powder, Guinness, and vanilla extract. Over medium heat whisk the ingredients until smooth. Once it has a smooth texture, remove from heat.
Step 2: Prepare the Cake Batter
Next pour your chocolate beer sauce into the bowl with the dry ingredients. I used a plastic spatula to scrape every last bit of sauce out of the pan.
Add two eggs to the batter & mix with a hand whisk.
Once it's all mixed together, and free of lumps, pour equal amounts into the two cake pans.
Place cake pans with batter into the oven for 30 minutes.
Step 3: Frosting
While your cakes are cooling, prepare the frosting.
Add the 2 cups of softened butter and 3 cups of powdered sugar to you mixer bowl. Turn mixer on low and gradually increase the speed to medium. Once the powdered sugar has blended into the butter, begin to gradually add the remaining powdered sugar and the Baileys Irish cream. Mix on medium to high speed for about 3-5 minutes. Frosting should be light and fluffy.
Step 4: Frost Your Cake
Place one layer of your cake on a cake plate, and use about 1/3 of the frosting to frost this layer. This will create a nice thick layer of frosting between your layers.
Place your second cake layer on top of the frosted bottom layer, and use the remaining frosting to frost the rest of the cake.
While your cake is now ready to be eaten, it's much better if you chill it in the refrigerator for at least an hour before eating.
Step 5: Eat Your Cake!
Excellent with a cold Guinness Extra Stout, a cold glass of milk, or a hot cup of coffee with Baileys Irish Cream.
