1 cake


  • 1 large sweet potato, peeled and cut into chunks

  • 1 ½ cups all-purpose flour

  • 1 cup white sugar

  • 1 teaspoon baking powder

  • 2 eggs

  • 2 teaspoons vanilla extract

  • ¾ cup butter

  • ½ cup pumpkin seeds

  • ½ cup brown sugar

  • 3 large ripe bananas, mashed

  • ½ cup golden raisins (Optional)


  1. Preheat oven to 350 degrees F (175 degrees C). Grease a 5x8-inch baking dish.

  2. Place sweet potato into a large pot and cover with water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain and mash sweet potato until smooth.

  3. Sift flour, white sugar, and baking powder together in a large bowl. Whisk eggs and vanilla extract together in another large bowl.

  4. Melt butter in a saucepan over medium heat; cook and stir pumpkin seeds and brown sugar in hot butter until brown sugar is melted, 1 to 2 minutes. Stir bananas and mashed sweet potato into pumpkin seed mixture. Remove from heat and cool slightly.

  5. Stir banana mixture into egg mixture until well-combined. Pour banana-egg mixture into flour mixture and stir until batter is just combined; stir in raisins. Pour into prepared baking dish.

  6. Bake in the preheated oven until a toothpick inserted into the center of the cake comes out clean, about 1 hour.
