Ingredients

Scale

Frosting Ingredients

  • ½ cup (1 stick / 113 g) unsalted butter, softened
  • ½ teaspoon strawberry extract
  • 1 pinch kosher salt
  • 2 cups (250 g) confectioners’ sugar
  • 1 jar (7.5 ounces) strawberry marshmallow creme or fluff

Instructions

  1. Beat Butter Until Fluffy: In a large bowl, use a handheld mixer to beat the softened butter on medium speed for about 2 minutes until it becomes light and fluffy.
  2. Mix in Extract and Salt: Add the strawberry extract and a pinch of kosher salt to the butter and continue mixing to incorporate these flavorings evenly.
  3. Add Confectioners’ Sugar Gradually: Slowly add the confectioners’ sugar, about ½ cup at a time, mixing well after each addition to keep the mixture smooth and lump-free.
  4. Beat on High Speed: After all the sugar is incorporated, beat the mixture on high speed for 2 to 3 minutes until the frosting is smooth, fluffy, and fully combined.
  5. Fold in Strawberry Marshmallow Creme: Using a spatula, gently fold in the strawberry marshmallow creme until it is fully blended with the frosting, creating a light and airy texture with a strawberry flavor.

Notes

  • Ensure the butter is softened to room temperature for easier mixing and a smoother frosting.
  • Do not overbeat once the marshmallow creme is added to avoid deflating the airy texture.
  • This frosting is best used immediately or stored in the refrigerator and brought to room temperature before spreading.
  • For a stronger strawberry flavor, adjust the strawberry extract quantity according to taste.
