1 box yellow or chocolate cake mix
1/2 cup (1 stick) butter, softened
1 (8oz) package cream cheese
1/2 large bag of powdered sugar
1 bag chocolate chips
Combine the cake mix, 1 egg and the butter. The ingredients will become a stiff dough. Press into the bottom of a 13x9 inch greased baking pan.
Bake at 350F for 30 to 40 minutes, or until the cream cheese mixture is set and slightly browned. Sprinkle with chocolate chips and return to the oven for a few minutes until the chips have softened.
Cool and slice into squares.
