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 – Provides sweetness and structure for the fluff.
Water – Helps dissolve the sugar and create the syrup base.
Corn Syrup – Adds smoothness and prevents crystallization, keeping the fluff creamy. I used light corn syrup.
Egg Whites – Whipped to give the fluff its light, airy texture.
Cream of Tartar – Stabilizes the egg whites and helps maintain the fluffy consistency.
Vanilla Extract – Adds a sweet, classic flavor to the marshmallow spread.

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.

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.

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 your stand mixer bowl and whisk are completely clean and free of grease. Any residual grease can prevent the egg whites from whipping properly.
Don’t Skip the Cream of Tartar: Cream of tartar is essential for stabilizing the egg whites. It cannot be substituted if you want light, fluffy fluff.
Careful When Combining Ingredients: The hot corn syrup mixture must be added slowly and carefully to the whipped egg whites. Pouring too quickly can deflate the eggs or cause splattering.
Flat Fluff Fix: If your fluff ends up flat, don’t worry! You can re-whip it by hand or with a mixer to restore its airy texture.
Whisk Corn Syrup Properly: While heating the sugar and corn syrup, avoid constant whisking. Over-mixing can create sugar crystals, resulting in a grainy texture.
Use Room Temperature Ingredients: Room temperature egg whites and other ingredients incorporate more easily, ensuring a smooth, consistent texture.
Patience is Key: Whipping the egg whites to stiff peaks and slowly adding the syrup takes time, but it ensures a stable, glossy, and fluffy marshmallow spread.
Storage Tip: Fluff tends to firm up slightly after sitting. Simply stir or re-whip gently before using if needed.
