Preheat oven 350F. Mix box of cake mix with eggs, water, and oil and put in a 13x9 baking dish. Bake for 30-35 minutes until cake tests done. Let cake cool.
In a saucepan, warm your chocolate chips with your heavy cream on low to medium heat until a smooth glaze forms. Then pour and spread over top of cake. Let cake set for an hour or two or eat immediately. My family went crazy for this easy dessert.
