Ingredients

1 cup unsalted butter, softened

1 jar marshmallow creme (7 oz)

3 cups powdered sugar, sifted

2 tablespoons heavy cream

1 teaspoon vanilla extract

1/8 teaspoon salt

Instructions

1. Place the softened butter into a large mixing bowl and beat for 3 to 5 minutes until pale, creamy, and fluffy.

2. Add the marshmallow creme and mix until fully smooth and combined.

3. Slowly add the powdered sugar one cup at a time while mixing on low speed.

4. Add the vanilla extract and salt, then continue mixing until incorporated.

5. Pour in the heavy cream one tablespoon at a time until the frosting reaches your preferred consistency.

6. Beat the frosting for an additional 2 to 3 minutes to create a light and airy texture.

7. Use immediately for frosting cakes, cupcakes, brownies, or cookies.

8. If the frosting becomes too soft, refrigerate for 10 to 15 minutes before decorating.

Notes

Use room-temperature butter for the smoothest and fluffiest texture.

Sift the powdered sugar before mixing to prevent lumps in the frosting.

Chill the frosting briefly if decorating in a warm kitchen to help maintain stability.
