Step 1: Prepare Your Ingredients
- Soften the Butter: Ensure your unsalted butter is softened to room temperature. This helps create a smooth frosting. If you’re in a hurry, you can cut the butter into small pieces to soften it faster.
Step 2: Beat the Butter
- Cream the Butter: In a large mixing bowl, use an electric mixer to beat the softened butter on medium speed until it’s creamy and smooth, about 2-3 minutes. Scrape down the sides of the bowl as needed.
Step 3: Add the Marshmallow Fluff
- Incorporate the Fluff: Add the marshmallow fluff to the butter. Beat together on medium speed until well combined, about 1-2 minutes. The mixture should be fluffy and light.
Step 4: Add Powdered Sugar
- Gradually Add Sugar: With the mixer on low speed, gradually add the powdered sugar, one cup at a time. This will help prevent a powdered sugar cloud in your kitchen. Mix until incorporated.
Step 5: Add Vanilla and Cream
- Mix in Vanilla: Once all the powdered sugar is added, add the vanilla extract and mix until combined.
- Adjust Consistency: Add heavy cream or milk, one tablespoon at a time, mixing on medium speed until you reach your desired frosting consistency. You can add more or less depending on how thick or thin you want your frosting.
Step 6: Add a Pinch of Salt
- Season to Taste: Add a pinch of salt to balance the sweetness. Mix well to incorporate.
Step 7: Frost Your Cake or Cupcakes
- Frosting Cakes: Once your frosting is ready, use it immediately to frost cakes, cupcakes, or cookies. You can pipe it using your favorite piping tips or simply spread it with a spatula.
Storage
- Store in the Refrigerator: If you have leftover frosting, store it in an airtight container in the refrigerator for up to 1 week. When ready to use, bring it back to room temperature and rewhip to restore its fluffy texture.
- Freezing: You can also freeze the frosting for up to 3 months. Thaw it in the refrigerator overnight and rewhip before using.
Tips for the Perfect Marshmallow Buttercream Frosting
- Use Quality Ingredients: The flavor of your frosting will largely depend on the quality of the butter and vanilla extract you use.
- Whip it Good: For a lighter frosting, whip the butter longer. The more air you incorporate, the fluffier your frosting will be.
- Flavor Variations: You can add other flavors such as almond extract, chocolate cocoa powder, or food coloring to customize your frosting.
