Ingredients

Lucky Charms Cupcakes

Vanilla Buttercream Frosting

Instructions

Lucky Charms Cupcakes

  • Preheat oven to 350°F. Line a cupcake pan with paper liners.
  • Combine the flour, Lucky Charms crumbs, baking powder, and salt in a small bowl. Set aside.
    3/4 cups all purpose flour, 1/2 cup Lucky Charms cereal crumbs, 1 1/4 teaspoons baking powder, 1/4 teaspoon salt
  • In the bowl of an electric stand mixer fitted with a paddle, add the sugar and butter. Beat until light and fluffy, about 3 to 5 minutes.
    1/2 cup granulated sugar, 1/4 cup unsalted butter
  • Mix in the eggs one at a time, then the vanilla extract.
    2 eggs, 1 teaspoon vanilla extract
  • Gradually alternate adding the flour mixture and heavy cream until everything is just combined.
    1/2 cup heavy cream
  • Fill each cupcake liner about half way full. This is about 2 tablespoons of batter per cupcake.
  • Bake for 15-18 minutes, or until a toothpick inserted into the center comes out clean. Remove from the pan and allow to fully cool.

Vanilla Buttercream Frosting

  • Combine powdered sugar, butter, 2 tablespoons of the heavy cream and vanilla extract in the bowl of an electric mixer fitted with a whisk attachment.
    4 cups powdered sugar, 1/2 cup unsalted butter, 2-3 tablespoons heavy cream, 2 teaspoons vanilla extract
  • Mix on low speed for a minute, then medium speed until everything its well combined and smooth. If needed, add more heavy cream to get a semi-firm consistency.
  • Once the baked cupcakes have cooled, top them with the frosting using a piping bag and tip or a butter knife.
  • Decorate with Lucky Charms marshmallows.

Notes

Tips & Techniques

  • Set the butter and eggs out about an hour before you begin to allow them to come to room temperature. This is important so that they can be easily blended into the batter without lumps.
  • Make Lucky Charms cereal crumbs by adding just the oat part of the cereal (not the marshmallows) to a food processor and pulse until it resembles very fine crumbs.
  • You can add food coloring to turn the frosting any color you would like for it to be or use clear vanilla extract for even whiter frosting.
