2/3 C confectioner's sugar
3 tsp. dry flavoring such as lemonade mix, orange breakfast drink mix, cocoa or Vanilla Powder, instant flavored coffee or cappuccino. (I used instant espresso.)
Place the glaze mix ingredients into a sandwich bag. Label this bag "glaze mix" and attach it to the other bag with a twist tie.

Place one bag cake mix and one bag glaze mix in each coffee cup and attach these baking instructions:
