Homemade Marshmallow Fluff

My family loves marshmallow fluff.  We make Nutter Fluffer Sandwiches.  Think PBJ with marshmallow fluff instead of jelly.  Sweet, gooey, wonderful stuff!  (My family was also known to mix peanut butter with syrup for sandwiches.  Let’s just say we aren’t the most health conscious bunch you ever met!)  We are also fans of all the sweet goodies that Marshmallow Fluff goes into.

Imagine my surprise when I learned you can make Marshmallow Fluff at home. It is AMAZING!  And for about a quarter of the cost of buying it at the store.  I am told that this Marshmallow Fluff can be used in recipes – though I haven’t made it that far myself.  I have used it for my Nutter Fluffers, and as a filling for Whoopie Pies (and I will be sharing that recipe with you next week!).

Here is all you need:

  • 3 egg whites at room temperature
  • 2 cups light corn syrup
  • 1/2 teaspoon salt
  • 2 cups sifted powdered sugar
  • 1 tablespoon vanilla extract

Put the first three ingredients in a large bowl and mix on high for 5 minutes.  My KitchenAid stand mixer with the whisk attachment did a great job with this.  The eggs will emulsify and the mixture will turn white and double in volume.  Add the powdered sugar and mix in well on low.  Add the vanilla and mix on low again, just until combined.

This made a large batch.  I used some to fill 10 large Whoopie Pies, and still had 2 1/2 pints left over.  It will keep in your fridge for up to two weeks. If you don’t want such a big batch, you can try dividing the recipe – but I’d suggest you share a jar or two with friends.  Friends don’t let friends miss out on Nutter Fluffer Sandwiches!
