Ingredients

Scale

Sweet Potato Cupcakes

  • 2 medium sweet potatoes (about 1 cup mashed)
  • 1 1/2 cups all-purpose flour
  • 1 cup granulated sugar
  • 2 large eggs

Marshmallow Frosting

  • 1 cup marshmallow fluff or marshmallow creme
  • 2 tablespoons unsalted butter, softened
  • 1/2 teaspoon vanilla extract
  • Optional: pinch of salt

Instructions

  1. Prepare the Sweet Potatoes: Preheat your oven to 350°F (175°C). Pierce the sweet potatoes with a fork and bake them directly on the oven rack or on a baking sheet for about 45-60 minutes, until tender. Allow them to cool, then peel and mash to yield about 1 cup of mashed sweet potato.
  2. Make the Cupcake Batter: In a large mixing bowl, whisk together the flour and sugar. Beat in the eggs, then fold in the mashed sweet potatoes until the batter is smooth and well combined.
  3. Bake the Cupcakes: Line a cupcake pan with paper liners and fill each about two-thirds full with the batter. Bake in the preheated oven for 20-25 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and let cool completely.
  4. Prepare the Marshmallow Frosting: In a bowl, beat the softened butter until creamy. Gradually add the marshmallow fluff and vanilla extract, continuing to beat until smooth and fluffy. Add a pinch of salt if desired to balance sweetness.
  5. Frost the Cupcakes: Once the cupcakes have cooled completely, spread or pipe the marshmallow frosting evenly over the tops. Serve immediately or refrigerate until ready to serve.

Notes

  • You can prepare the sweet potatoes ahead of time and refrigerate the mashed sweet potatoes for up to 3 days.
  • For a more spiced flavor, add cinnamon or nutmeg to the cupcake batter.
  • The cupcakes keep well in an airtight container in the refrigerator for up to 3 days.
  • Allow cupcakes to come to room temperature before serving for best texture and flavor.
