Step-by-Step Marshmallow Fluff Royal Icing Instructions

Preparing Your Marshmallow Fluff Royal Icing

With a prep time of just 5 minutes and no cooking required, this Marshmallow Fluff Royal Icing couldn’t be easier to make. All you’ll need is a large mixing bowl, a hand mixer or stand mixer, and a few simple ingredients.

1- Start by separating the egg whites from the yolks, making sure there’s no trace of yolk in the whites. This will ensure the icing whips up light and fluffy.
2- In the mixing bowl, beat the egg whites on high speed until they’re glossy and stiff peaks form. This may take a few minutes, so be patient and let the mixer do its work.
3- With the mixer still running, gradually add in the powdered sugar, one spoonful at a time. This will help the sugar incorporate smoothly and prevent any lumps.
4- Once all the sugar has been added, the icing should be thick, creamy, and glossy. Give it a quick taste and add the vanilla extract, mixing until it’s fully incorporated.
5- Finally, gently fold in the 1/2 cup of marshmallow fluff, being careful not to deflate the airy meringue.
6- And just like that, your Marshmallow Fluff Royal Icing is ready to spread, pipe, or enjoy straight off the spoon!

Pro Tips for Success

  • Make sure all your equipment is grease-free and your mixing bowl is spotlessly clean – any traces of fat can prevent the egg whites from whipping properly.
  • Use room temperature egg whites for best results – they’ll whip up lighter and fluffier than cold egg whites.
  • Go slowly when adding the powdered sugar to prevent it from flying everywhere. Patience is key for a silky smooth icing.
  • Don’t overmix the icing once the marshmallow fluff is incorporated, or you could end up deflating all that lovely air you just whipped in.
  • For the prettiest piped designs, use a piping bag fitted with your favorite decorative tip.
