Ingredients
Sweet Potato Cake
- 2 large sweet potatoes or 2 c. sweet potato puree
- 2 sticks butter
- 1 cup brown sugar packed
- 2 eggs
- 1 cup flour
- ¼ cup cornstarch
- 1 teaspoon baking soda
- 1 teaspoon baking powder

- 3 cups powdered sugar
- 2 tablespoons bourbon

Instructions
Sweet Potato Cake
- Peel sweet potatoes and cut into 1” cubes. Bring a large pot of salted water to a boil. Drop in the sweet potato cubes, reduce heat, and simmer 12 to 15 minutes until tender enough to easily puncture with a fork. Drain sweet potatoes and mash until smooth. Let cool.
- Prepare a 9" cake pan (see notes). Preheat oven to 350℉.
- In a large mixing bowl, beat butter and sugar until fluffy. Add egg and beat until incorporated. Beat in cooled sweet potatoes.
- Add in the vanilla and mix.
- Add the flour, cornstarch, baking soda, baking powder, and salt and mix until just incorporated.
- Spread into prepared cake pan and bake for 50-60 minutes. Cool in the cake pan for about 5 minutes then flip out onto a wire rack to cool completely.
Marshmallow Frosting
- Cream butter until fluffy. Add the rest of the frosting ingredients and beat until well combined.
- Spread onto cooled cake, slice, and enjoy!
Notes
To easily line a cake pan, spray the bottom and sides of the pan with nonstick spray. Cut a circle out of parchment paper, place in the bottom of the pan, and then spray the parchment with nonstick spray
This cake can be made as a two layer cake by dividing the batter between two cake pans and reducing the bake time to 35-45 minutes. Once the cakes have cooled, spread the marshmallow frosting between the layers and on top of the top layer.
An 8x8 baking pan can be used in place of a 9" round cake pan.
