Ingredients

Scale
  • 1 1/2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup buttermilk
  • 1/2 cup vegetable oil
  • 1 cup hot water
  • For the Marshmallow Frosting: 1 cup unsalted butter, softened
  • 3 cups powdered sugar
  • 1/2 cup marshmallow fluff
  • 1 teaspoon vanilla extract
  • 2 tablespoons heavy cream or milk
  • Mini marshmallows for topping

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
  2. In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
  3. Add the egg, vanilla extract, buttermilk, and vegetable oil to the dry ingredients. Mix on low speed until just combined. Do not overmix.
  4. Carefully pour the hot water into the batter and mix on low speed until smooth. The batter will be thin.
  5. Divide the batter evenly among the prepared cupcake liners, filling each about two-thirds full.
  6. Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean. Let the cupcakes cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
  7. To make the marshmallow frosting, beat the softened butter in a large bowl until creamy.
  8. Gradually add the powdered sugar, mixing until combined.
  9. Beat in the marshmallow fluff and vanilla extract. Add the heavy cream one tablespoon at a time until the frosting reaches a smooth, spreadable consistency.
  10. Once the cupcakes are completely cool, pipe or spread the marshmallow frosting onto each one.
  11. Top the frosting with mini marshmallows or a light dusting of cocoa powder before serving.

Notes

  • For an extra cozy flavor, you can use hot cocoa mix in place of some of the cocoa powder in the cake batter.
  • If you want a toasted marshmallow look, briefly place the frosted cupcakes under a broiler for 30 seconds, watching closely to prevent burning.
  • These cupcakes taste best when served the day they are made.
