Icing is hard for me to write a recipe for because most times I wing it! But here is my chocolate icing recipe to the best of what I do:
1.5 sticks of butter (soft)
3 cups of powdered sugar
2 tablespoons of milk (can replace with heavy cream to be richer)
1.5 tablespoons of Hershey’s Dark Cocoa Powder
Whip butter in a stand mixer. Slowly add in powdered sugar, alternating with a little bit of milk. When you get to a consistancy you like, add in cocoa powder!
