Ingredients

1 cup butter, softened1 cup sugar1 large egg1 teaspoon vanilla extract1-3/4 cups all-purpose flour1/2 cup baking cocoa1-1/2 teaspoons baking powder1/4 teaspoon salt24 bite-size chocolate-covered peppermint pattiesICING:18 bite-size chocolate-covered peppermint patties4-1/2 teaspoons butter

Preparation

In a large bowl, cream butter and sugar until light and fluffy. Beat in egg and vanilla. Combine the flour, cocoa, baking powder and salt; gradually add to creamed mixture and mix well. Cover and refrigerate for 30 minutes or until easy to handle.

Shape dough into two 6-in. rolls; wrap each in plastic wrap. Refrigerate for 2 hours or until firm.

Unwrap dough and cut into 1/4-in. slices. Place one slice on waxed paper; top with a peppermint patty and a second dough slice. Press edges of dough together to completely cover the peppermint patty. Repeat.

Place 2 in. apart on ungreased baking sheets. Bake at 325° for 11-13 minutes or until set, watching carefully. Cool for 5 minutes before removing to wire racks.

For icing, in a microwave, melt peppermint patties and butter; stir until smooth. Cut a small hole in the tip of a pastry bag or in a corner of a food-safe plastic bag; fill with icing. Pipe over cookies as desired.
