Ingredients
1 cup unsalted butter, softened
7 ounces marshmallow creme
4 cups powdered sugar, sifted
2 teaspoons vanilla extract
2 tablespoons heavy cream or whole milk
1/4 teaspoon salt
Instructions
1. Allow the butter to soften at room temperature for 30 to 45 minutes before starting.
2. Place the softened butter into a large mixing bowl and beat for 3 to 5 minutes until pale and fluffy.
3. Add the marshmallow creme and continue mixing until fully smooth and airy.
4. Slowly add the sifted powdered sugar one cup at a time while mixing on low speed.
5. Add the vanilla extract and salt, then mix until combined.
6. Pour in the heavy cream one tablespoon at a time until the frosting reaches the desired consistency.
7. Increase the mixer speed and whip the buttercream for an additional 3 to 4 minutes until extra light and fluffy.
8. Use immediately to frost cakes, cupcakes, brownies, or cookies.
Notes
Always use softened butter instead of melted butter for the smoothest texture.
Sift the powdered sugar before mixing to avoid lumps in the frosting.
Chill the buttercream for 10 to 15 minutes before piping detailed decorations for cleaner designs.
