Ingredients
  

Frosting Ingredients
  • 1 cup unsalted butter, softened Adds rich flavor and creamy texture; don’t use margarine for best results.
  • 1 cup marshmallow fluff The star ingredient that gives the frosting its delightful sweetness and airy consistency.
  • 3-4 cups powdered sugar Adjust based on desired sweetness; a sifter helps avoid lumps.
  • 1 teaspoon vanilla extract Adds a warm, inviting flavor; use pure vanilla extract for the best taste.
  • 1-2 tablespoons heavy cream or milk Incorporate as needed for consistency; almond milk works well for a lighter alternative.

Method
 

Preparation
  1. In a large mixing bowl, beat the softened butter until creamy.
  2. Add the marshmallow fluff and vanilla extract, and beat until well combined.
  3. Gradually add powdered sugar, one cup at a time, mixing well after each addition until the frosting is light and fluffy.
  4. If the frosting is too thick, add heavy cream or milk, one tablespoon at a time, until the desired consistency is reached.
  5. Use the frosting immediately on cakes, cupcakes, or other desserts.

Notes

Common mistakes include not softening the butter adequately which can lead to a lumpy frosting, adding too much powdered sugar at once, and forgetting to aerate your frosting by mixing well. Pro tips: Use food coloring for vibrant colors, add flavors like almond or lemon extract, and serve chilled for a firmer texture if piping decorations.
