Ingredients:
- 2 1/2 cups flour (300g)
- 1 tablespoon baking powder
- 1 teaspoon baking soda
- 2 teaspoons ground cinnamon
- 2 cups sugar
- 1 cup vegetable oil
- 4 large eggs
- 3 cups grated raw sweet potatoes (about 450g, 1 to 2 medium sweet potatoes)
- 1 1/2 cups chopped pecans
Directions:
Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch (23x33cm) baking pan.
In a large bowl, whisk together the flour, baking powder, baking soda, and ground cinnamon. Set aside.
In a stand mixer, beat together the sugar and vegetable oil until well combined. Add the eggs one at a time, beating well after each addition.
Gradually add the flour mixture to the wet ingredients, mixing on low speed until just combined.
Gently fold in the grated sweet potatoes and chopped pecans, reserving a few pecans for sprinkling on top.
Pour the batter into the prepared pan and smooth the top. Bake for 50 to 60 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely before frosting.
Marshmallow Buttercream Frosting:
In a stand mixer, beat the butter until smooth and creamy.
Add the marshmallow cream and mix until well combined.
Gradually add the powdered sugar and a pinch of salt, mixing until smooth and fluffy.
Spread the heavenly buttercream frosting on top of the cooled cake, and for an extra touch of elegance, sprinkle the remaining pecans and a dash of cinnamon on top.
Notes:
- For a nut-free version, you can omit the pecans or replace them with toasted coconut flakes for a delightful twist.
- Feel free to experiment with different spices like nutmeg or ginger to add your own personal touch.
