Sweet Potato Cupcakes

Light and moist, these cupcakes are flavored with earthy, warm spices, then finished off with an easy toasted marshmallow frosting.
Prep Time:25 minutes
Cook Time:20 minutes
Total Time:45 minutes
Servings:12 cupcakes

Ingredients

For the cupcakes:

  • 1 cup sweet potatoes cooked and mashed
  • 2 cups all-purpose flour
  • 2 eggs at room temperature
  • ½ cup unsalted butter at room temperature
  • ½ cup milk at room temperature
  • 1 ½ cups brown sugar
  • 1 teaspoon vanilla extract
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1 teaspoon ground ginger
  • ½ teaspoon ground nutmeg
  • ¼ teaspoon ground cloves

For the frosting:

  • ½ cup marshmallow creme
  • ¼ teaspoon cream of tartar
  • ⅓ cup granulated sugar
  • 2 egg whites
  • 3 tablespoons cold water
  • 1 teaspoon vanilla extract
  • ⅛ teaspoon salt

Instructions

  • Preheat the oven to 350°F. Prepare a muffin tin and line the cavities with liners.
  • In a large bowl, beat brown sugar and butter. Add eggs one at a time and beat well to combine. Add sweet potatoes and vanilla extract.
  • In a separate bowl, combine flour, cinnamon, ginger, nutmeg, cloves, baking powder and soda, and salt. Add half of this mixture to the batter and stir well to combine. Add milk and remaining flour, and stir well to combine.
  • Add batter to the muffin tin and bake for 20 minutes. Let cool.
  • In a pan, beat the cream of tartar, sugar, egg whites, cold water, and salt and place over boiling water, beat until stiff peaks form. Add marshmallow crème and vanilla extract, then beat well to combine.
  • Top the cooled cupcakes with frosting and enjoy!

Notes

  • Take the time to add each egg one at a time to ensure the best mixture, beating after each one is added.
  • The frosting is simpler to make than you might imagine. Just keep beating it until you have stiff peaks and then it’s ready.
  • Don’t add the frosting until the cupcakes are completely cool. Otherwise, the frosting will start to run and look messy.
  • Not everyone is a marshmallow fan. If that applies to you, a vanilla cream cheese frosting would also be really good here.
