Ingredients

  • 2 cups all-purpose flour
  • 1.5 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1.5 teaspoons ground cinnamon
  • 1.5 cups mashed sweet potatoes (cooked and cooled)
  • 1 cup granulated sugar
  • 1/2 cup brown sugar
  • 1/2 cup vegetable oil
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup buttermilk
  • 1/4 cup brown sugar (for the cinnamon swirl)
  • 1 teaspoon ground cinnamon (for the cinnamon swirl)
  • 1 cup powdered sugar (for the glaze)
  • 2-3 tablespoons milk (for the glaze)
  • 1/2 teaspoon vanilla extract (for the glaze)

Instructions

  • Preheat the oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  • Mix dry ingredients: In a bowl, whisk together flour, baking powder, baking soda, salt, and 1.5 teaspoons ground cinnamon.
  • Combine wet ingredients: In a large bowl, blend mashed sweet potatoes, granulated sugar, brown sugar, and vegetable oil until smooth.
  • Add eggs and liquids: Add eggs one at a time, mixing briefly after each. Stir in vanilla extract and buttermilk.
  • Combine mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined.
  • Prepare cinnamon swirl: In a small bowl, mix 1/4 cup brown sugar and 1 teaspoon ground cinnamon.
  • Layer the cake: Pour half the batter into the pan. Spread half the cinnamon swirl mixture over the batter. Add remaining batter and swirl the other half of the cinnamon mixture into the top.
  • Bake for 35-40 minutes, or until a toothpick inserted comes out clean.
  • Prepare the glaze: Whisk powdered sugar, milk, and vanilla extract until smooth. Spread over the cooled cake.

Notes

Ensure the sweet potatoes are fully cooled before mixing to avoid curdling the batter.
Storage: Keep in an airtight container at room temperature for up to 3 days.
Variation: Add chopped pecans or raisins to the cinnamon swirl for added texture.
