I love Triple Chocolate cake and it is relatively easy.
1--4 serving package of cooked chocolate pudding mix not instant, made according to directions on the package. While still hot, add 1 box chocolate cake mix. Mix thoroughly and pour in the pan. Sprinkle with chocolate chips if desired. We usually don't bother. Bake according to the cake mix box.
**If you can only find the 6 serving cooked pudding mix, make according to directions and take out 1 cup.
