2 boxes of Devil's Food cake mix
2/3 cup vegetable oil
1 (8 ounce) package cream cheese, softened
1/2 cup (1 stick) butter, softened
4 cups powdered sugar
1 teaspoon peppermint extract
Preheat oven to 350 degrees. In a large bowl combine the cake mix, eggs, and oil. The batter will be very stiff. Roll batter into 1 inch balls and place on cookie sheet. Flatten balls slightly with fingers. Bake 12 minutes. Let cool slightly on cookie sheet before removing to wire rack to finish cooling.
In a small bowl, combine the cream cheese and butter until completely blended. Gradually add in the powdered sugar and peppermint extract and mix until the icing is smooth.
Spread one cookie with icing and top with another cookie.
Ideas: You can add red or green food coloring to frosting. You can roll the edges of the cookie in sprinkles or crushed candy cane.
