Heat about 3 tablespoons of heavy cream in a bowl in the microwave for a minute or on the stovetop in a sauce pan just until hot.  Remove from heat source and stir in 1 cup of chocolate chips (I prefer semi sweet) with fork or whisk until the chocolate is melted and smooth, then spread on top of the cooled cake.

Recipe Notes

  • The cake in the photo on this post  is topped with this frosting.
  • When baking a cake in a Bundt pan, it took me a LONG time to figure this out: Generously grease the pan- key word generously. I use PAM, a cooking spray. Any type of cooking spray, or brushing the pan with oil will work as well. I don't use solid shortening bc it may leave a white film on the baked goods after they cool. Spray the pan right before you fill with batter.
  • This recipe works with any combo of: choc cake/choc pudding, choc cake/vanilla pudding, yellow cake/choc pudding.
  • Works with low fat sour cream, but better texture with regular sour cream.
  • You can make this in two 9 inch loaf pans. Start checking for doneness at the 45 min mark. Line the bottom of the pan with parchment or wax paper, grease paper.
  • Great with or without the frosting. Stores well for about 5 days if covered.
