THE BEST and EASIEST chocolate cake/ cupcakes OF ALL TIME!!!!!

ok, super built up title. but  NO lie i have tried many many variations of your basic chocolate cake, and this one trumps them all by FAR!! even better than any ive tried from scratch. I've made it now at least 3 times for Dicks birthday, and gretas and mothers day. LOVE.

1 box devil’s food cake mix
1 small pkg Jello instant chocolate pudding mix
1 cup sour cream
1 cup vegetable oil
4 eggs, beaten
1/2 cup milk
1 tsp vanilla
2 cups mini chocolate chips (or substitute with chopped up reece peanut butter cups- awesome)

Preheat oven to 350 degrees F. In a very large bowl, mix together everything except chocolate chips. Batter will be thick. Stir in the chocolate chips. Pour batter into cake pan of choice (I normally use two 9-inch pie pans). For cooking time, I use the cooking times on the back of the devil’s food cake box as a guide and usually add 10 mins to whatever it says. Then I do the toothpick check, and if it’s not done, I check on it every 5 mins after that. It usually takes around 45 mins for two, 9-inch pie pans.
