What is Marshmallow Fluff?

Marshmallow fluff is usually in a jar at the store. But after a little research I discovered how easy it is to make at home. The best part is it taste better. Marshmallow fluff is light and fluffy texture similar to melted marshmallows.

It is stretchy, sticky and airy similar to the inside of a marshmallow.

How to Whip Egg Whites?

The most important part of Marshmallow Fluff is whipping the egg whites.

  • Making stiff peaks – This is the key in making the fluff with cloud-like texture.
  • Cream of Tartar – This is added to keep the air locked in the egg whites.
  • Hot Sugar Water – Combining the water with the eggs makes the Marshmallow Fluff stretchy and full of flavor. 


Ingredients - sugar, water, corn syrup, egg whites, cream of tartar, vanilla extract
  • Sugar
  • Water
  • Corn Syrup
  • Egg Whites
  • Cream of Tartar
  • Vanilla Extract

Get the complete ingredient list at the bottom.

Ingredient Substitution Ideas

  • Meringue – Instead of the egg whites, you can use 3 tablespoons meringue powder and 5 tablespoons of water.
  • Honey – Instead of the corn syrup, you can use honey, glucose syrup, or rice malt syrup. If you use one of these substitutions, your marshmallow fluff will probably be a different color.

Step by Step Instructions

Sauce pan of water with bowls of sugar and corn syrup on the side

Step 1 – First you will need to combine the water, sugar and corn syrup in sauce pan over medium heat. Whisk the mixture occasionally.

Combining the ingredients in a stand mixer

Step 3 – Place a candy thermometer in the mixture and heat the sugar syrup mixture until the candy thermometer reaches 240 degrees F.

Beat egg whites with the cream of tartar

Step 3 – Next, while the sugar mixture is heating to the desired temperature, beat the egg whites and cream of tartar in bowl of a stand mixer with the whisk attachment.

Continue beating mixture

Step 4 – Beat on medium high and continue to whip the egg whites until soft peaks form (about 2 minutes). When the sugar mixture reaches 240 degrees F, remove from heat.

Slowly add the sugar mixture into the egg white mixture

Step 5 – Keep the mixer running on low, then slowly add sugar mixture to the egg whites.

Pour in vanilla into the cream mixture

Step 6 – Once all of the sugar mixture is added, turn the mixer to medium-high speed and whip until stiff peaks form, about 7-9 minutes scraping down of the sides of the bowl occasionally. Add the vanilla into the mixing bowl during last minute of whipping. The mixture will be thick and glossy white.

Variation Ideas

I usually make a classic version of this homemade marshmallow creme recipe by using the vanilla to flavor the fluff. However, you can easily add in different ingredients to change up the flavor.

  • Lemon – Stir in lemon juice or zest once it’s ready to give it a citrus flavor.
  • Cocoa – Stir in ¼ cup of cocoa to the final few minutes of the mixing time to make a chocolate marshmallow fluff.

Expert Tips

  • Clean Mixing Bowl – Make sure that your stand up mixer bowl is clean and grease free. If there is any grease on the bowl, it will prevent the egg whites from whipping properly.
  • Cream of Tartar – The only ingredient that you can NOT substitute for this recipe is the cream of tartar. It is a necessary ingredient for this marshmallow fluff recipe.
  • Combining Ingredients – Be very careful when working with the heated corn syrup mixture as it will be very hot. Carefully and slowly add it into the whipped eggs white.
  • Flat Fluff – If the marshmallow fluff becomes flat. The fluff can be re-whipped by hand or you can add it back into the mixer to re-whip it again to make it fluffy.
  • Whisking Corn Syrup – Do not whisk the corn syrup and sugar mixture constantly while it’s heating. As this could cause sugar crystals to form which will give your marshmallow fluff a grainy texture.
  • Room Temperature Ingredients – It’s best to use room temperature ingredients as they combined better when mixing.
