1 yellow cake mix
2 eggs
1 sm. pkg. instant butterscotch pudding, prepared according to directions
1 c. butterscotch chips
1 c. chocolate chips

Combine cake mix and eggs and beat until smooth. Add prepared pudding to cake mixture and blend. Pour into greased 9 x 13 inch baking pan and bake for 35 to 40 minutes at 350 degrees. After 20 minutes of baking time, sprinkle butterscotch and chocolate chips onto the cake. If chips are added sooner they will sink to the bottom of pan. Cool brownies before cutting into squares.
