Corn Syrup Free Marshmallow Fluff

July 3, 2017

Marshmallow fluff is fun & nostalgic. But since I’m older and have kids I now read labels and YIKES! there is some scary stuff listed on the label. We also try not to eat corn syrup. Did you know there is a substitute for corn syrup? Well there is and it’s simple, just water and sugar.

I wanted to make a s’mores cake for my husband, Aaron’s, birthday and of course you need marshmallow for that. So I thought I’ll make homemade fluff; it turned out great.

This marshmallow fluff is glossy, light, airy, sticky, sweet, fun, and most importantly super easy to make. There is no candy thermometer needed.

How will you eat this? In my family they just wanted it by the spoonful! Top your ice cream with it, make a s’mores, put in hot chocolate or in a milkshake, or of course just take a spoonful of it.

This is also versatile, you can make different flavors.  You can also make and give as gifts.

How do you eat marshmallow fluff? I would love to get some new ideas!

Please share:
  1. Hello, your recipe looks wonderful. I would love to know if you can use your marshmallow fluff to cover a Baked Alaska dessert I would like to make for our Christmas dessert. Wondering how it would stand up in the freezer cause I wish to make it a day before I plan to serve it and obviously it has to be kept frozen.
    Then either torched or baked for a few minutes in a very hot oven to brown the meringue before serving.
    The picture on your site looks much like a Swiss Meringue recommended for Baked Alaska recipes along Italian and ordinary meringues but like that one doesn’t have to use a thermometer or heat over a stove.
    Very impressive fluff!

    1. Thanks for the nice words, Deena! I do not know how it would stand up in the freezer. I can tell you that I had mine in the refrigerator for 2 weeks and it maintained it’s form, it didn’t deflate, melt or separate. I think it would be fine to place in the freezer. Please let me know how it worked for you. I’ve never had a Baked Alaska but have always wanted to try one.

      1. Thanks so much for your reply Allison! Great hearing from you!
        I look forward to trying your recipe very much.
        Happy Holidays to you and yours!
