Cook one box of chocolate pudding mix according to directions. When done immediately pour in one dry chocolate cake mix. {I put right in the pan} Mix well and pour into 9x13 pan, and spread out. Sprinkle top with 12 oz chocolate chips. Bake til tests done with toothpick {30-40 min}. I want, you can bake in a jelly roll pan and cut in bars. There are so many variations to use, for example, vanilla pudding, banana cake mix and chocolate chips, or butterscotch pudding, spice cake and nuts. Just use your imagination. Hope you all like it as well as my family does. It is excellent for taking somewhere, since there is no frosting for any thing to stick to. This is my first offering, I have just joined.
