I can't remember how I came across this recipe. It was posted somewhere on Facebook, I think. Anyway, here it is: Chocolate Stout Cupcakes with Bailey's Frosting.
I'm not a really big fan of cake to begin with, but we tried making these a week or two ago and they are delicious.
Our kids don't even like the smell of beer, but they enjoyed these as well. The recipe says that the cakes are safe for kids, since the alcohol in the beer cooks off, but the frosting still has alcohol in it since it's not cooked and therefore it's best to label them as adult only cupcakes. Our kids are 14 and 17 yrs old, and we let them have the cakes w/ frosting. 3-4 table spoons of Bailey's spread across a dozen cakes is pretty weak.
One thing we had a little trouble with was the icing. Following the recipe to the letter left us with some pretty liquidy frosting. We had to keep adding more confectioner's sugar to it to thicken it up and then we let it sit in the fridge for a while as well.
