Marshmallow Frosting

Oct 24, 2026 (Leave a Comment)

If you're in need of a frosting that doesn't use eggs, butter, or oil, marshmallow frosting is a great option. It's the same recipe you use for making marshmallows except that you work with it while it's fluid (before it sets) to frost cakes and cupcakes.

And here's a cool little tip. If the marshmallow fluff firms up before you've had a chance to frost with it you can gently melt marshmallows to get it fluid again. I use a microwave on a low setting for 10 to 15 seconds, or place them in a warm oven for several seconds.

Marshmallow frosting takes the shape of the surface it's added to. If you prefer a bit more shape, try my meringue recipe using egg whites. They're great for adding to the top cupcakes and cakes, like my ghostly cupcakes.

Marshmallow Frosting

If the marshmallow fluff firms up before you've had a chance to frost with it you can gently melt marshmallows to get it fluid again. I use a microwave on a low setting for 10 to 15 seconds, or place them in a warm oven (not hot but around 200 degrees F or so).
For SCD use honey.

Equipment

  • standing mixer with whisk attachment or a hand mixer with whisk attachment

Ingredients
 
 

  • 3 tablespoons gelatin
  • 1 cup maple syrup or honey
  • 1 teaspoon vanilla extract

Instructions
 

  • Place the gelatin in the bowl of a standing mixer with a whisk attachment (or hand mixer).
  • Pour ½ cup of the water over the gelatin and put it aside for a few minutes to absorb the water.
  • Add the ½ cup of the remaining water and maple syrup or honey to a saucepan and place it on a medium heat.
  • Bring to a steady boil without letting it foam over the saucepan. Boil the mixture for about 10 minutes, or use a candy thermometer to bring it to about 240℉.
  • Carefully pour the hot mixture over the gelatin and then add the vanilla extract.
  • Start whisking the mixture and slowly increase the speed to medium-high and let it go for about 10 minutes.The mixture will go from a dark liquid to creamy white while still being fluid.
  • Use the marshmallow to frost cupcakes, cakes, and of course make more marshmallows.
