CHOCOLATE FROSTING:

Instructions

PREP OVEN AND PAN:

  • Move the oven rack to the middle position and preheat the oven to 350 degrees F.

MAKE FROSTING:

  • While the cake is baking, melt butter in a medium saucepan over medium heat.
  • Whisk in sugar, Dr Pepper, cocoa powder, and vanilla.
  • Stir constantly until the mixture comes to a boil. Then, reduce the heat and boil for 1 minute.

Notes

● Cherry Dr Pepper could be used for a fruity flavor twist.
● Chocolate frosting could be substituted for a whipped cream or buttercream frosting.
● The cake is not overly sweet - the frosting is what makes this cake sweet.
● Nuts or sprinkles can be added on top of the frosting before it cools.
● This cake can be stored for up to 3 days at room temperature.
