So I should totally cheat and SAY that I posted this the day after I posted the cake. But that would be lying. Yes, and that would be naughty. SO, here's the coffee icing to compliment this cake, happy nomming! I actually modified this recipe from food.com - I know I thought I'd surprise you a little there.
1/2 cup softened butter
1 tsp vanilla
2 cups powdered sugar
1 1/2 tbs cooled coffee (or milk)
3 tsp Starbucks Iced VIA Coffee granules
To explain, I always have a smidge of coffee left over from the morning run. This is perfect for making this icing, if you have no coffee lying about milk will do as well. Also, the iced VIA granules make a very smooth, tasty, icing because they disappear into the mixture so it's not grainy. I recommend starting with 2 tsp of the granules then adding an additional teaspoon if you like it a little more coffee flavored. I love coffee. Obviously.
Dissolve VIA in your cooled coffee or milk.
Mix butter and vanilla together until creamy. Add powdered sugar and mix well on medium speed. Add coffee mixture to mixing bowl. Beat on high until light and fluffy.
