Homemade Marshmallow Fluff

Homemade Marshmallow Cream

Marshmallow fluff is a spreadable marshmallow cream that closely resembles a whipped and sweetened cloud. Food for angels.

Marshmallow fluff is most famous for being half of the duo that makes up the beloved fluffernutters. Peanut butter and fluff sandwiches. You can also use it to make moon pies, broiler s’mores or to frost a cake since it’s almost identical to Italian meringue.

A gooey dollop dropped into hot cocoa is heavenly bliss. Of course if none of this suits your fancy you can always eat it off a spoon. . . it’s pretty hard not to.

The process of making fluff is not at all complicated, but requires a candy thermometer and a stand mixer. Corn syrup and sugar is heated to the softball stage and drizzled into egg whites that have been beaten into stiff peaks. They are whipped together on high speed resulting in billowy mounds of super sweet fluff.

This recipe uses corn syrup, a product that has been around since the late 1800’s. Our ancestors recognized it as food. It is not the same thing as high fructose corn syrup. I’m not afraid to use it. Or eat it. Occasionally.

Update: The Strawberry Fluff is finally here! Eggless and Corn Syrup Free. I also have one for Gingerbread Fluff!

Homemade Marshmallow Fluff

Marshmallow fluff is a spreadable marshmallow cream that closely resembles a whipped and sweetened cloud!


3 large egg whites
2/3 cup plus 2 tablespoons sugar
3/4 cup light corn syrup
1 teaspoon pure vanilla extract


  1. Beat egg whites together until light and frothy using an electric stand mixer with the whisk attachment. With the mixer running, slowly pour in 2 tablespoons sugar; beat until soft peaks form.
  2. In a large saucepan, combine 1/3 cup water, corn syrup, and remaining 2/3 cup sugar. Place over medium heat and cook until boiling. Start cooking over medium heat stirring occasionally but never taking your eyes off it. Raise heat to medium high and continue cooking until mixture reaches the soft-ball stage, about 240 degrees F on a candy thermometer, it will take about 10-15 minutes. (The hot syrup may bubble up the sides, turn heat down briefly or remove pan from heat, once the syrup goes back down raise heat and continue cooking.)
  3. Drape an old, clean kitchen towel over the front and side of the mixer, leaving one side open to pour in the syrup. With the mixer on low, slowly add hot syrup to egg-white mixture ( make sure kids and pets are not nearby, this could scar you for life, people(!) and scares the living daylights out of me!). Increase mixer speed to high and continue beating for 6-8 minutes. Add vanilla and continue to beat until mixture looks like marshmallow cream, 2-4 minutes more.
  4. Allow to cool, spoon and store in tightly sealed jars in the refrigerator up to a month.

    Going to try out the fluff, bc I can’t find a successful marshmallow recipe made without gelatin. If you know of one can you email it to me. Thank you :)

      Hi Judith! I experimented over and over again with making fluff without gelatin and all my recipes fell flat. If I do find one I will let you know.

        Thank you so much!! By the way I just made your fluff and it was fantastic and now I’m sick bc I ate to much. Its delicious, I was unsure when I was boiling the sugar mixture, the term a “softball”. I didn’t know what that meant, so I just guessed it as it was getting thicker. I would raise my spatula and it would almost make a triangular shape as it dripped down and stay like that. Then I turned it off and brought it over to the whipped eggwhites mixture and mixed as you stated in the instructions. This was so fun to make as we came to the final results. Very pleased, it could also be used like cake frosting.

        Hi Judith! I’m so glad the fluff turned out well for you! It is fun to make! And to eat! :-) It doesn’t compare to the type you buy. It’s so much better. Thanks for making it!

    Can this be use as frosting for cupcakes or will it fall flat? I tried using marshmallow fluff as frosting but it fell flat. Hope you can help! Thanks

    I just finished this trying to make something different and trying my hand at handmade sweets. I substituted maple syrup(the real stuff) for the corn syrup and HOLY COW! This stuff is amazing! It’s not too sweet and it was so easy to make! I can’t wait to make more.

    Thanks so much! This is fantastic! I’m using it in a Sweetapolita recipe for a dark chocolate cake with raspberry buttercream and marshmallow filling.

      Hi Amanda! I think you have golden syrup there? You can use that instead. I’ve used honey before too although it does affect the taste a little.
