Why You’ll Love This Cake
What I love most about this sweet potato butter cake is how it captures the essence of fall in every slice. The sweet potatoes add incredible moisture and natural sweetness, while the warm spices like cinnamon and nutmeg create that cozy, comforting flavor. It’s similar to sweet potato pie but in cake form!
This cake stays moist for days and actually tastes better the next day as the flavors meld together. It’s also incredibly versatile – delicious on its own or dressed up with glazes and toppings.
Ingredients You’ll Need
-
1 cup unsalted butter, softened
-
2 cups granulated sugar
-
4 large eggs, room temperature
-
1½ cups mashed sweet potatoes (cooled)
-
2½ cups all-purpose flour
-
2 teaspoons baking powder
-
½ teaspoon baking soda
-
½ teaspoon salt
-
1 teaspoon ground cinnamon
-
½ teaspoon ground nutmeg
-
¼ teaspoon ground cloves
-
1 teaspoon vanilla extract
-
½ cup whole milk
Step-by-Step Instructions
Prepare the Sweet Potatoes
First, I peel and cube 2-3 large sweet potatoes, then boil them in salted water for 15-20 minutes until fork-tender. I drain them completely and mash until smooth, then let them cool to room temperature. This is important so they don’t melt the butter!
Mix the Batter
I preheat my oven to 350°F and generously grease and flour a bundt pan or 9×13 inch pan. In a large bowl, I cream together the softened butter and sugar until light and fluffy – about 3-4 minutes. This creates the perfect texture!
Then I add eggs one at a time, beating well after each addition. I mix in the mashed sweet potatoes and vanilla extract until well combined.
In a separate bowl, I whisk together the flour, baking powder, baking soda, salt, and all the spices. I add the dry ingredients to the wet mixture alternately with the milk, beginning and ending with the dry ingredients. I’m careful not to overmix!
Bake to Perfection
I pour the batter into my prepared pan and smooth the top. I bake for 55-65 minutes until a toothpick inserted in the center comes out clean. The cake should be golden brown and spring back when lightly touched.
I let it cool in the pan for 10 minutes, then invert onto a wire rack to cool completely before glazing or serving.
Serving Suggestions
This cake is amazing on its own, but I love serving it with a brown butter glaze, maple pecan topping, or simple powdered sugar glaze. A scoop of vanilla ice cream on the side takes it to the next level! It’s perfect with hot coffee or spiced chai tea.
Tips for Customization
-
Add ½ cup chopped pecans to the batter for extra crunch
-
Use roasted sweet potatoes instead of boiled for deeper flavor
-
Try a cream cheese frosting instead of glaze
-
Add a tablespoon of orange zest for brightness
-
Swap half the all-purpose flour with whole wheat for nuttier flavor

Make sure your butter is properly softened and cream it well with the sugar. Also, don’t overmix the batter once you add the flour.
