Holy chocolate goodness!! Got this recipe from my friend Leslie and it is amazing!! Zac has informed me that they are "the best cupcakes ever!" I made them for a baby shower and sent leftover to work with him the next morning - all with rave reviews!
1 (18.25 oz) pkg devils food cake mix
1 (5.9 oz) pkg instant chocolate pudding mix
1 cup sour cream
1 cup vegetable oil
1/2 cup warm water
2 cups milk chocolate chips (the recipe calls for semi-sweet but I really liked the milk)
In mixer or large bowl, combine all ingredients except chocolate chips. Stir in chocolate chips.
Bake at 350° for 20 minutes (or 50-55 min for 9x13 or bundt cake) until toothpick comes out clean. DO NOT overbake!!
Cool about 20 minutes in pan, then cool completely on rack. Frost or dust with powdered sugar.
UPDATE 10/2013: If you want to increase the yumminess and richness, try using melted butter in place of the oil and warmed milk in place of the warm water. Mmm.
