Ingredients
2 cups cooked and mashed sweet potatoes (about 2 medium sweet potatoes)
1 cup unsalted butter, softened
1 ½ cups granulated sugar
4 large eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
2 teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
1 teaspoon ground cinnamon
½ teaspoon ground nutmeg
½ cup milk or buttermilk
Optional Toppings:
Cream cheese frosting
Powdered sugar
Chopped pecans or walnuts
Instructions
1. Prepare the Sweet Potatoes
Peel and cube the sweet potatoes, then boil or steam until tender. Mash them until smooth and set aside to cool slightly.
2. Preheat the Oven
Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or line it with parchment paper.
3. Cream Butter and Sugar
In a large mixing bowl, beat the softened butter and sugar together until light and fluffy. This step ensures your cake is airy and soft.
4. Add Eggs and Vanilla
Beat in the eggs one at a time, followed by the vanilla extract. Mix until well incorporated.
5. Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
6. Mix Wet and Dry Ingredients
Gradually add the dry ingredients to the butter mixture, alternating with milk or buttermilk. Fold in the mashed sweet potatoes until the batter is smooth and creamy.
7. Bake the Cake
Pour the batter into the prepared pan and spread evenly. Bake for 45–55 minutes, or until a toothpick inserted into the center comes out clean.
8. Cool and Frost
Allow the cake to cool in the pan for 10–15 minutes, then transfer to a wire rack. Frost with cream cheese frosting if desired, or simply dust with powdered sugar and sprinkle with chopped nuts for a rustic finish.
Tips for the Perfect Sweet Potato Cake
Use naturally sweet potatoes: Varieties like Beauregard or Garnet are perfect.
Mash thoroughly: No lumps for a smooth, consistent batter.
Room temperature ingredients: Butter, eggs, and milk at room temperature ensure a better rise and texture.
Spice it up: Adjust cinnamon, nutmeg, or even a pinch of ginger for extra warmth.
Make ahead: This cake tastes even better the next day as the flavors develop.
