Equipment

  • 9x13 baking pan

Ingredients

  • 1 cup mashed baked sweet potato about 2 medium sized
  • 4 large egg
  • 1 cup sour cream
  • 3/4 cup vegetable oil
  • 1 yellow box cake mix

Center Swirl

  • 1 cup light brown sugar
  • 2 teaspoon cinnamon
  • 1/4 teaspoon nutmeg
  • 1 cup pecans, chopped

Icing

  • 1.5 cup powdered sugar
  • 1/4 cup milk
  • 1 teaspoon vanilla extract

Instructions

  • Bake the sweet potatoes until tender. Allow them to cool enough to handle, remove the skins, and mash until smooth. Measure 1 cup for the recipe.
  • Preheat the oven to 350°F. Prepare a 9×13-inch baking dish with nonstick spray.
  • In a large bowl, mix together the mashed sweet potato, eggs, sour cream, and vegetable oil. Add the yellow cake mix and stir until combined.
  • In a separate bowl, combine the brown sugar, cinnamon, nutmeg, and chopped pecans.
  • Spread half of the cake batter into the prepared baking dish. Sprinkle the brown sugar mixture evenly over the batter, then spread the remaining cake batter over the top.
  • Run a knife gently through the layers a few times to create a swirl. Do not completely mix the layers together.
  • Bake for 30–35 minutes, or until the center is cooked through and a toothpick inserted into the cake comes out clean.
  • While the cake cools briefly, whisk together the powdered sugar, milk, and vanilla until smooth.
  • Spread the glaze over the cake while it is still warm. The glaze will spread easily and set into a thin icing as the cake cools.
  • Allow the cake to cool and the icing to set before slicing and serving.
