6 tablespoons butter, softened
2 cups confectioners' sugar
1 9 ounce box of chocolate wafers
1. In the bowl of an electric mixer, beat butter until smooth. Add confectioners' sugar; beat until light and fluffy. Divide mixture among small bowls, using one for each flavor. Stir in desired flavorings to taste, thinning with milk if needed.
2. Spread half a box of chocolate wafers with a small amount of filling; top with remaining cookies. Press gently to spread filling to the edges.
