Spicy Cream Cheese Rum Frosting

  • 4 ounces cream cheese softened

  • 1/8 teaspoon ground allspice
  • 1/8 teaspoon ground nutmeg
  • 1/8 teaspoon ground cloves
  • 2 cups confectionery or powdered sugar
  • heavy whipping cream About 8 tablespoons or enough so that you can spread frosting easily or pour from a small pitcher on top of cake


  • Whisk together all-purpose flour, salt, baking soda, baking powder, cinnamon, nutmeg and ginger. Make sure this is mixed well and set aside. In a large bowl beat the butter, eggs, white sugar, brown sugar, sweet potatoes, buttermilk, sour cream and vanilla extract together. Add the flour mixture to the creamed mixture and mix well. Stir in nuts and raisins.
  • Spray a 10 inch bundt pan with cooking spray, pour in batter. Bake in preheated 350 degree oven for 55 to 60 minutes testing for doneness as ovens vary. Remove from oven and let cool for 15 minutes before removing from pan. Frost cake with your favorite frosting once totally cooled

Frosting Instructions

  • Whip cream cheese and butter with mixer. Add rum, allspice, nutmeg, cloves and powdered sugar. Whisk in whipping cream until you get the spreading consistency you want.


You could just put regular cream cheese frosting or any other frosting on this cake you like. We like the spices and rum in the frosting.
