Instructions

Cupcakes

  1. Preheat oven to 350 F. Line muffin pan with cupcake liners. Depending on how thick they are, use two cupcake liners in each cup.
  2. In a bowl, combine flour, baking powder, and salt. Set aside.
  3. In a medium bowl, beat butter and sugar together until light and fluffy, 2-3 minutes.
  4. Add in egg, egg white, and vanilla; beat until blended.
  5. On low speed, gradually beat in flour mixture, one third at a time, alternating with milk, beginning and ending with flour.
  6. Divide batter among liners and bake for 18-20 minutes or until a toothpick inserted in the center comes out clean. Cool 10 minutes in the pan. Transfer to a wire rack to cool completely.
  7. Once cupcakes are cooled completely, use an apple corer to cut a hole in the center of each cupcake. Press down the cake inside the hole. Set aside until ready to frost.

Frosting

  1. On medium speed, beat butter until light and fluffy, about 2 minutes.
  2. On low speed, beat in fluff until just combined, about 30 seconds.
  3. Gradually beat in sugar and vanilla; beat on medium until fluffy.
  4. Place about ⅓ cup of frosting into a small bowl. Stir in ⅓ cup of rainbow sprinkles. Transfer to a piping bag fitted with a large round tip.
  5. Place about ¼ cup of frosting into a small bowl. Stir in a few drops of yellow food coloring. Transfer to a piping bag fitted with a grass tip.
  6. Transfer remaining frosting to a piping bag fitted with a large star tip.

Assembly

  1. Pipe the frosting with rainbow sprinkles into the center of each cupcake.
  2. Frost the tops of the cupcakes using the frosting with the star tip. Pipe in a circle to create a party hat shape.
  3. Add rainbow sprinkles to the tops of the cupcakes.
  4. Using the yellow frosting, pipe a small amount on the top of the white frosting hat to make a pom pom.
  5. Add two mini oreo cookies to each cupcake to make Mickey ears.
