A light, fluffy, and irresistibly sweet strawberry frosting made with marshmallow fluff and real strawberry preserves. Perfect for piping on cupcakes or frosting a layer cake.

Ingredients

Scale

1 cup unsalted butter, softened
1 1/2 cups marshmallow fluff
1/3 cup strawberry preserves
1 1/2 to 2 cups powdered sugar, sifted
1/2 teaspoon vanilla extract
1 pinch salt
Optional: a few drops red or pink food coloring
Optional: 1 teaspoon freeze-dried strawberry powder

Instructions

  1. Allow your butter to come to room temperature for smooth blending.
  2. Using a hand or stand mixer, beat the butter on medium-high for 3–4 minutes until light and fluffy.
  3. Add the marshmallow fluff and mix on medium until well combined and fluffy.
  4. Mix in the strawberry preserves or puree until the frosting turns a light pink.
  5. Gradually add the powdered sugar while mixing on low, then increase to medium-high. Adjust sugar to achieve desired consistency.
  6. Add vanilla extract and salt, then mix just until combined.
  7. Taste and adjust with more preserves or powdered sugar if needed.
  8. If the frosting is too soft, chill for 10–15 minutes before piping or spreading.
  9. Use immediately or store in an airtight container in the fridge for up to 5 days.
  10. Re-whip before using if refrigerated.

Notes

  • For the best texture, ensure butter is softened but not melted.
  • Sift powdered sugar to prevent lumps in the frosting.
  • For a stronger strawberry flavor and color, add freeze-dried strawberry powder.
  • Frosting can be made 2 days ahead; re-whip before using.
