Preheat oven to 350 degrees F. Line 2-1/2-inch muffin cups with paper bake cups; set aside. Prepare cake mix according to package directions, folding crushed cookies into batter. Spoon batter into prepared cups, filling each about half full.

Bake according to package directions. Cool in pan on wire racks for 5 minutes. Remove cupcakes from pan and cool completely.

Use a pastry bag with star tip to pipe Creamy White Frosting on each cupcake or spread frosting on cupcakes. Top each cupcake with a miniature cookie. Makes 24 cupcakes.

Creamy White Frosting: In a large mixing bowl, combine 1/2 cup shortening and 1 teaspoon vanilla. Beat with electric mixer on medium to high speed for 30 seconds. Slowly add 1 1/4 cups powdered sugar, beating well. Add 1 tablespoon milk. Slowly beat in 1 cup additional powdered sugar. Beat in enough additional milk, 1 tablespoon at a time, to make frosting spreadable. Makes about 1 3/4 cups.
