Cake Ingredients:

  • 1 cup 2 sticks butter, room temperature
  • 1/2 cup sugar
  • 1/2 cup light brown sugar
  • 2 eggs
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon ground cloves
  • 1 teaspoon cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/2 cup vanilla ice cream melted
  • 1/2 cup rum I prefer to use a dark or spiced rum, but any rum you have on hand would work.
  • 1/2 teaspoon vanilla extract

Spiced Whipped Cream Frosting Ingredients:

  • 1 cup heavy whipping cream
  • 1/2 cup powdered sugar sifted
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon cinnamon
  • 1/2 teaspoon ground cloves
  • 1/2 teaspoon vanilla extract


Cake Directions:

  • Preheat oven to 350 F.
  • Cream the butter and sugar.
  • Mix in the eggs.
  • In a separate bowl, whisk together the flour, baking soda, baking powder, cloves, cinnamon, and nutmeg.
  • Add the dry ingredients to the butter/sugar mixture and mix until just combined.
  • Stir in the vanilla ice cream, rum, and vanilla extract.
  • Fill mugs with batter to about 1/3 full.
  • Baking time will vary depending on the depth and thickness of your mugs. Begin checking on them at around thirty minutes. They should bounce back when touched lightly and a toothpick inserted into them should come out dry.

Whipped Cream Frosting Directions:

  • Whip heavy whipping cream until it’s light and fluffy.
  • Mix in all other ingredients until just combined.
