Ingredients Needed

The ingredients for marshmallow fluff are super simple. You also probably have them all on hand! Whenever a recipe calls for marshmallow fluff and you don’t have any, it’s so easy to make this instead! If you are looking for exact measurements, they can be found below in the recipe card.

Water: This little bit of H2O is essential to help dissolve the sugar and corn syrup and create the base of our marshmallow fluff.
Granulated Sugar: Sugar makes everything better, including marshmallow fluff! It’s what gives the fluff its signature sweetness. If you’re looking for a healthier alternative, you can try using honey or maple syrup instead. You can also use stevia to make sugar-free marshmallow fluff!
Corn Syrup: The glue that holds the marshmallow fluff together! It also gives it a sticky, gooey texture.
Egg Whites: Egg whites are the secret to giving marshmallow fluff that light and fluffy texture. They act as a stabilizer and help the fluff hold its shape.
Cream of Tartar: Cream of tartar is another stabilizer that helps our marshmallow fluff hold its shape. It also helps the egg whites whip up faster and taller.
Vanilla Extract: Vanilla extract adds a delicious flavor to marshmallow fluff. It’s the finishing touch that makes the fluff taste so good! Try using pure vanilla extract or make your own blend for the best flavor possible! If you don’t have any vanilla extract, you can try using almond extract or any other flavoring you like.

How to Make Homemade Marshmallow Fluff

Making homemade marshmallow fluff is a breeze – it’s so easy, you’ll wonder why you ever bought it from the store! Just whip up some egg whites, sugar, a few other ingredients, and then you’ve got yourself a batch of airy, delicious marshmallow fluff! It’s perfect for spreading, dipping, or just eating straight from the bowl. Let’s get started!

Sugar Mixture: Add the water, sugar, and corn syrup to a small saucepan and cook over medium heat until all the sugar dissolves and the mixture reaches 240 degrees Fahrenheit on a candy thermometer.
Clean Bowl: Wipe down the bowl to a stand mixer and the whisk attachment with white vinegar or lemon juice to eliminate any grease.
Whisk: Add the egg whites and cream of tartar to the cleaned bowl and whisk on medium speed until soft peaks form, about 2 minutes.
Remove From Heat: Once the sugar mixture reaches 240 degrees Fahrenheit, remove it from the heat.
Combine: Turn the mixer to low speed and slowly pour the sugar syrup into the egg whites. Once all the syrup has been added, increase the speed to medium high and whip until you reach stiff peaks.
Add Vanilla: Add in the vanilla and mix until combined. Store in an airtight container for up to 2 weeks.

Tips and Tricks

Incorporate these simple tips into your next batch, and you’ll be making marshmallow fluff like a pro! It’s so good, you’re going to want to eat it straight from the jar.

Whip It: The key to perfect marshmallow fluff is to whip the egg whites and other ingredients until they’re super fluffy and light. Make sure to reach stiff peaks! Don’t be afraid to whip it for a few extra minutes – it’s worth it!
Use a Candy Thermometer: When you’re heating up the sugar and corn syrup, make sure you don’t overheat it. If it gets too hot, it can affect the texture of the fluff. Use a candy thermometer to make sure it reaches the right temperature.
Egg White Mixture: When you’re whipping the egg whites, make sure you’re doing it at a low speed to start. Once they start to froth up, you can increase the speed. Don’t rush it – it takes a little time to get that perfect marshmallow fluff texture.
Switch Up the Flavor: Don’t be afraid to get creative with your marshmallow fluff! Add some food coloring for a fun twist, or mix in some chocolate, white chocolate, or peanut butter for a delicious flavor. The possibilities are endless!
