Directions:

Heat oven to 350 degrees F. Remove wrappers from chocolates.

Beat butter, brown sugar and granulated sugar in large bowl until well blended. Add egg, milk and vanilla. Beat until well blended. Stir together flour, baking soda and salt; add to butter mixture, blending thoroughly.

Bake 8 to 10 minutes or until set. Cool slightly; remove from pan to wire rack. Press thumb again into each indentation if needed. Cool completely.

Divide and tint frosting to match cookie colors. Place about 1/2 teaspoon frosting in each indentation. Press chocolate piece onto each cookie.
