1 package (18 1/4 ounces) German chocolate cake mix
2/3 cup cold butter or margarine
1 cup (6 ounces) semisweet chocolate chips
1 can (15 ounces) coconut-pecan frosting
1/4 cup milk
Directions
Place cake mix in a bowl; cut in butter until crumbly. Press 2 1/2 cups into a greased 13-by-9-by-2-inch baking pan. Bake at 350 degrees for 10 minutes; immediately sprinkle with chocolate chips. Drop frosting by tablespoons over the chips. Stir milk into the remaining crumb mixture; drop by teaspoonful over top.
Bake 25–30 minutes longer or until bubbly around the edges and top is cracked. Cool on a wire rack. Refrigerate for 4 hours before cutting.
