Ingredients You’ll Need
For the Cupcakes
- 1 cup mashed sweet potato (cooked and cooled)
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1/2 cup unsalted butter, softened
- 1 cup brown sugar
- 2 large eggs
- 1/2 teaspoon vanilla extract
- 1/2 cup buttermilk
For the Marshmallow Fluff Frosting
- 1 cup marshmallow fluff
- 1/2 cup unsalted butter, softened
- 2 cups powdered sugar
- 1 teaspoon vanilla extract
- Optional: toasted marshmallows or crushed graham crackers for garnish
How to Make Sweet Potato Cupcakes with Marshmallow Fluff Frosting
Step 1: Prepare the Cupcake Batter
- Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
- In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg. Set aside.
- In a large bowl, cream the butter and brown sugar until light and fluffy. Beat in the eggs, one at a time, then stir in the mashed sweet potato and vanilla extract.
- Gradually add the dry ingredients to the wet mixture, alternating with the buttermilk, and mix until just combined.
Step 2: Bake the Cupcakes
Divide the batter evenly among the cupcake liners, filling each about 2/3 full.
Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Allow the cupcakes to cool completely before frosting.
Step 3: Prepare the Marshmallow Fluff Frosting
- In a large bowl, beat the butter until smooth and creamy.
- Gradually mix in the powdered sugar until well combined.
- Add the marshmallow fluff and vanilla extract, then beat on high speed until the frosting is light and fluffy.
Step 4: Frost and Decorate
Using a piping bag or a spatula, frost each cupcake with the marshmallow fluff frosting.
For extra flair, garnish with toasted marshmallows or a sprinkle of crushed graham crackers.
Tips for Perfect Sweet Potato Cupcakes
- Use fresh sweet potatoes: Baking or steaming sweet potatoes brings out their natural sweetness. Avoid canned sweet potato puree if possible.
- Don’t overmix the batter: Mixing too much can make the cupcakes dense. Stop as soon as the ingredients are combined.
- Toast the frosting lightly: For a fun touch, use a kitchen torch to lightly toast the frosting for a caramelized effect.
