Mix:
1 devil's food chocolate cake mix
1 large box chocolate pudding
5 eggs
1 cube butter, melted
16 oz (regular size tub) sour cream
1 tsp. vanilla
a pinch of salt
Then add:
2 cups chocolate chips
Bake in a bundt pan at 350 for 55 minutes.
This is SOO good. It doesn't even need frosting. I sprinkled powdered sugar over it to make it look nice.
