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.
