Grandma’s Famous Sweet Potato Butter Cake

Ingredients

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

For the Butter Glaze (optional but delicious):

  • 1/4 cup (1/2 stick) unsalted butter
  • 1/2 cup granulated sugar
  • 1/4 cup water
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour a bundt pan or a 10-inch tube pan.
  2. Cream the butter and sugar in a large bowl until light and fluffy, about 3-5 minutes.
  3. Add eggs one at a time, beating well after each addition.
  4. Mix in the mashed sweet potatoes and vanilla extract until fully incorporated.
  5. In a separate bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
  6. Add the dry ingredients to the sweet potato mixture alternately with the milk, starting and ending with the flour. Mix just until combined — do not overmix.
  7. Pour batter into the prepared pan and smooth the top.
  8. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean.
  9. Make the glaze (optional): In a small saucepan, melt butter, sugar, and water over medium heat. Bring to a boil, stirring constantly, then remove from heat and stir in vanilla.
  10. When cake is done, let it cool in the pan for 10–15 minutes. Invert onto a wire rack. While warm, slowly spoon the butter glaze over the cake so it soaks in.
  11. Cool completely, slice, and enjoy Grandma’s sweet, buttery masterpiece!
