Description

A light, fluffy, and sweet marshmallow buttercream frosting made with butter, powdered sugar, almond extract, and marshmallow fluff. Perfect for cakes, cupcakes, and cookies.


Ingredients

  • 1 cup (2 sticks / 227 g) unsalted butter, softened
  • 4 cups (500 g) confectioners’ sugar
  • ½ teaspoon almond extract
  • 2 jars (7 ounces each) marshmallow creme or fluff

Instructions

  1. In a stand mixer fitted with the paddle attachment, beat the softened butter on medium speed for about 2 minutes until light and fluffy.
  2. Add the almond extract and mix until combined.
  3. Gradually add the confectioners’ sugar, about ½ cup at a time, starting on low speed. Once all is added, increase to high speed and beat for 2–3 minutes until creamy and smooth.
  4. Gently fold in the marshmallow creme by hand to maintain the fluffy texture. Use immediately or refrigerate for later use.

Notes

  • For a nut-free version, substitute almond extract with vanilla or imitation almond extract.
  • Chill frosting before use if piping intricate designs or for warm climates.
  • Re-whip chilled or thawed buttercream to restore fluffiness.
