Easy Homemade Marshmallow Fluff

For whatever reason, marshmallows always seemed like something that would be difficult to make at home. But, after making my homemade marshmallows and strawberry marshmallows, I quickly realized that was not the case. 

Now that I know just how easy homemade marshmallows are, I pretty much never buy them from the store. So I decided it was about time I put together a marshmallow fluff recipe. That way I have all my marshmallow bases covered! 

This recipe is so simple, so much better than the store-bought stuff, and is ready in under half an hour!

Marshmallow Fluff Ingredients

  • Corn Syrup, Granulated Sugar, and Water: The base of our marshmallow fluff. I recommend using light corn syrup for this recipe. It has a more mild flavor than dark corn syrup. 
  • Vanilla Extract: Adds a touch of flavor depth. 
  • Egg Whites and Gelatin: The combination of egg whites and gelatin gives the marshmallow creme structure.

  1. In a saucepan, combine corn syrup, sugar, water, and vanilla. Cook with a candy thermometer over medium-high heat, stirring occasionally, until the temperature reaches 240ºF. 
  2. Using a stand mixer, whisk the egg whites and gelatin until frothy, then slowly drizzle in the sugar mixture, mixing on low speed.

Tips and Notes

  • Use a candy thermometer. The thermometer is key to make sure the sugar mixture reaches just the right temperature. Once it reaches 240ºF, pull it off the heat!
  • Whip the egg whites and gelatin well. This is what gives the marshmallow fluff its structure and light, fluffy texture. I recommend using a stand mixer to yield the best results. 
  • This is not meant to replace store bought marshmallow fluff in any recipe that may call for it. It’s not the same consistency as the marshmallow creme you may purchase at the store, so it won’t work the same way. 

How to Serve Marshmallow Creme

Room Temperature: This homemade marshmallow creme can be stored in an airtight container at room temperature for up to 1 week.  

Freezer: For longer storage, you can keep this marshmallow fluff in an airtight container in the freezer for up to 3 months. When you’re ready to use it, simply thaw it at room temperature, then enjoy. 

Are Melted Marshmallows the Same as Marshmallow Fluff?

Not quite, no. Regular marshmallows are made using a number of different stabilizing ingredients not usually found in marshmallow fluff—all of which help them hold their shape. 

These ingredients can include powdered sugar, cornstarch, and gelatin.
