Ingredients

  • Cake
  • 1 medium sweet potato
  • 1/2 cup butter
  • 3/4 cup sugar
  • 1/2 cup light brown sugar
  • 1/2 cup dark brown sugar
  • 4 eggs, room temperature
  • 3 cups flour
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 1/2 cup milk
  • Irish Whiskey Glaze
  • 1 cup Irish whiskey
  • 2 tablespoons brown sugar
  • 2 tablespoons confectioners' sugar
  • 1 tablespoon butter

Method

  • Preheat oven to 325°F Grease and flour a standard tube pan.
  • Cook sweet potato in boiling water until tender; or, for richer flavor, bake in the oven. Cool, peel and mash until you have 1 cup puree.
  • Cream butter together with sugars in a large mixing bowl. Mix in sweet potato puree. Add eggs, 1 at a time, beating well after each addition.
  • Sift flour, baking powder and salt together and add alternately with milk. Pour into pan and bake 60 to 70 minutes.
  • While cake is baking, make Irish Whiskey Glaze:
  • Combine whiskey, sugar and butter in a small saucepan. Bring to a boil to dissolve sugar.
  • When cake tests done remove to a rack. Pour a portion of glaze over hot cake in pan. Let soak in a little before adding all the glaze. Cool completely in pan and gently remove to a plate.
