Instead of cooking the topping for the prune cake, it also taste great with a cream cheese frosting. A batch of cream cheese frosting can be simply made after the cake cools by combine these simple ingredients:

  • 3-ounces of cream cheese
  • 1 cup of powdered sugar
  • 1 teaspoon of vanilla extract
  • Milk

Beat the cream cheese on high with an electric mixer. Then add in the powdered sugar and vanilla extract. Beat until well blended. Add in the milk, while continuing to beat, a little at a time until the frosting reaches a just right spreading consistency. Spread immediately on the cooled cake made from the old fashioned prune cake recipe.
