Ingredients

For the Cake Batter:

  • 1 cup mashed sweet potatoes (cooked and cooled)
  • 1/2 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 cup whole milk, room temperature
  • 1 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt

For the Cinnamon Swirl:

  • 1/3 cup brown sugar, packed
  • 1 1/2 teaspoons ground cinnamon
  • 2 tablespoons melted butter

For the Glaze:

  • 3/4 cup powdered sugar
  • 12 tablespoons milk
  • 1/2 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9-inch round cake pan or line it with parchment paper.
  2. In a mixing bowl, cream together softened butter and sugar until light and fluffy.
  3. Beat in eggs one at a time. Add vanilla and mashed sweet potatoes. Mix until smooth.
  4. In a separate bowl, whisk together flour, baking powder, baking soda, cinnamon, nutmeg, and salt.
  5. Gradually add dry ingredients to wet mixture, alternating with milk. Mix just until combined.
  6. In a small bowl, mix brown sugar, cinnamon, and melted butter to form the swirl.
  7. Pour half of the batter into the cake pan. Add half of the cinnamon swirl and lightly swirl it in with a knife.
  8. Repeat with remaining batter and cinnamon swirl.
  9. Bake for 35–40 minutes, or until a toothpick comes out clean. Let cool 10–15 minutes before transferring to a rack.
  10. Mix glaze ingredients and drizzle over the cooled cake.
