Orange Rum Cake Recipe (Makes two 8 inch round cakes)

  • 8 tablespoons butter
  • 2 cups sugar
  • 6 large eggs
  • zest of two large oranges
  • 1/2 teaspoon salt
  • 2 1/2 cups flour
  • 3 teaspoons baking powder
  • 2/3 cup heavy cream
  • 2 tablespoons orange juice
  • 1 cup dark rum

Meringue Buttercream Frosting

  • 1 cup sugar
  • 4 large egg whites
  • 3 sticks butter room temp
  • 1 tablespoon dark rum


Orange Rum Cake Recipe

  • Prepare two 8 inch round cake pans with parchment paper and butter.
  • Preheat the oven to 375 degrees.
  • In a large mixing bowl, beat the room temperature butter until pale yellow and thick.
  • Add in the sugar and eggs and beat again until fully incorperated.
  • Add in the orange zest and salt and beat, scraping down the sides of the bowl.
  • Sift flour and baking powder in a bowl and set aside.
  • Add orange juice to the heavy cream and set that aside.
  • With the mixer on medium speed, add the flour mixture and heavy cream into the batter, alternating between the two.
  • Divide batter between the prepared baking pans.
  • Bake for 25 to 30 minutes, do not overcook.
  • When you remove, puncture holes all over the top of the cakes and spoon 1/2 cup of rum over each of them. Let them cool before removing.

Meringue Buttercream Frosting

  • Add the sugar and the egg whites into a heatproof mixing bowl.
  • Fit the bowl over a pan of simmering water. Whisk constantly until the mixture is hot, sugar is dissolved and the egg whites are a little frothy. Do this for about 4 minutes. It should look like a shiny marshmallow cream.
  • With the whisk attachment, beat eggs on medium speed until cooled and thicker for about 5 minutes.
  • Switch to the paddle attachment and one at a time, add in one stick of room temperature butter beating until smooth. Enjoy the deliciousness!
