1/2 cup butter, slightly softened
1 box (2-layer size) devil's food cake mix
1 cup semi-sweet chocolate chips
1 cup butterscotch chips
1 cup flaked coconut
1 cup chopped pecans
1 can (14-oz) sweetened condensed milk
Preheat oven to 350 degrees.
In a large bowl, using a pastry blender or two knives, cut the butter into the cake mix until crumbly. Press the mixture onto the bottom of a 15 x 10-inch baking pan. Sprinkle the chocolate chips, butterscotch chips, coconut, and pecans over the cake mixture. Pour the sweetened condensed milk over the top.
Bake at 350 degrees for 20 minutes or until golden brown and puffed up in the center. Remove from oven and place pan on a wire rack to cool. Cut into 48 bars.
