Sharing is caring!

If you’ve ever made a recipe that calls for marshmallow fluff and realized you don’t have any on hand, don’t worry—making your own is easier than you think!

This light, fluffy, and sweet spread comes together in less than 15 minutes with pantry staples. Plus, it tastes way better than the store-bought version.

Homemade marshmallow fluff is perfect for making fluffernutter sandwiches, swirling into brownies, topping hot chocolate, or layering into s’mores-inspired desserts. Once you make it from scratch, you’ll never go back to the jarred stuff!

Ingredients You’ll Need

• 2 large egg whites, room temperature
• 1/2 cup granulated sugar
• 2/3 teaspoon pure vanilla extract
• 1/3 teaspoon of cream of tartar

Step-by-Step Instruction

Step 1: Prepare a heat-safe mixing bowl

Combine all the ingredients in a heat-safe bowl.

Step 2: Heat the mixture

Set the bowl over a saucepan of simmering water (double boiler style). Whisk constantly until the sugar dissolves completely and the mixture reaches about 160°F. This ensures the egg whites are safe to eat.

Step 3: Whip until fluffy

Transfer the mixture to your stand mixer. Using the whisk attachment, beat on high speed for 7–9 minutes until stiff, glossy peaks form. The mixture should appear thick and pillowy, almost like meringue.

Step 4. Store

Transfer the marshmallow fluff to a clean, airtight container. Store in the fridge for up to 2 weeks.

Tips for Success

• Use room temperature egg whites – they whip up faster and give the fluff more volume.
• Keep whisking while heating – you don’t want scrambled eggs! Constant movement keeps the mixture smooth.
• Flavor it up – swap the vanilla for almond extract, peppermint extract, or even maple syrup for a fun twist.

How to Use Homemade Marshmallow Fluff

• Spread between peanut butter sandwiches for a classic Fluffernutter.
• Stir into hot cocoa for a creamy topping.
• Swirl into fudge or brownies for a gooey, decadent treat.
• Use as filling for cakes, cupcakes, or whoopee pies.

Once you try this homemade version, you’ll see just how versatile and delicious marshmallow fluff can be. It’s sweet, soft, and melts perfectly into desserts.
