Step-by-Step Marshmallow Fluff Royal Icing Instructions
Preparing Your Marshmallow Fluff Royal Icing
With just a 15-minute total time, this Marshmallow Fluff Royal Icing comes together in a snap. You’ll need a stand mixer or hand mixer to whip up the ingredients to the perfect fluffy consistency.
1- Start by adding the softened unsalted butter to your mixing bowl. Beat the butter on medium-high speed until it’s light and creamy, about 2-3 minutes.
2- Next, add the marshmallow fluff to the bowl and continue mixing until the two are fully incorporated, creating a smooth, uniform mixture.
3- Gradually add the powdered sugar, 1 cup at a time, beating well after each addition. Scrape down the sides of the bowl as needed.
4- Once all the powdered sugar is incorporated, the icing should be thick, smooth, and glossy. Stir in the vanilla extract and salt until evenly distributed.
5- Using a spatula or spoon, the Marshmallow Fluff Royal Icing is now ready to be spread, piped, or dolloped onto your favorite cakes, cupcakes, or cookies.
6- For the best presentation, use an offset spatula to create swirls or peaks in the icing. Serve and enjoy your masterpiece!
Pro Tips for Success
- Make sure your butter is truly softened to room temperature before starting. This will ensure the icing comes together smoothly.
- Gradually add the powdered sugar to prevent a cloud of white dust in your kitchen. Scrape down the sides of the bowl as needed.
- Don’t over-mix the icing once the powdered sugar is incorporated. This can cause the icing to stiffen and become difficult to work with.
- For a lighter, fluffier texture, beat the icing on high speed for an extra minute or two after all the ingredients are combined.
