More like a sponge cake then an ordinary cake I would say. Quick and Easy
3 ounce chocolate pudding mix ( Quick cooking but I have used instant)
2 cups milk
1 pkg devils food cake box mix
1/2 cup semi sweet chocolate chips
1/2 cup walnuts
Prepare pudding mix with milk. Remove from heat. Blend dry cake mix into hot pudding mix. Mixture will be VERY thick and spongy. You might have to use your hand to mix batter/dough. Pat down/pour into greased 13 by 9. Sprinkle with nuts can chips. Bake 350 for 35 minutes.
