What you’ll need

  • mini marshmallows- 16 oz
  • water 3-5 tablespoons
  • 2 lbs powdered sugar
  • microwave

This will be sticky, if you mix by hand, place shortening or oil on your hands. This will make kneading it easier. If the fondant “tears” the fondant is too dry, add 1/2 teaspoon of water until it’s smooth.

Once it’s blended well, put it onto a smooth work surface.

I like making it the night before I use it, so the colors develop well.

Put a little shortening or oil on the exterior of the fondant, store it in a plastic zipper bag, and remove as much air as possible.

Keep at room temperature for up to a week, and then it can be put in the fridge for 2 another two weeks.

  1. Possibly stupid question. If you don’t add the food dye right away will the color still turn out right?

  2. Okay, I officially hate you. If I made those chicks, they'd come out looking like they just had a mammogram.

  3. This is the second time in as many weeks that I've seen posts for Marshmallow Fondant. Mostly I'm decorating cookies with royal icing. Last week I frosted and "decorated" a cake with buttercream frosting for only the second time in my life. This weekend I frosted cupcakes with the leftover buttercream. I've never used fondant and I will at some point try both cakes and cookies with this fondant. I can't believe that you can leave this out on the counter for a week! Thank you for the recipe

  4. That is super easy…and super cute!!! LOVE the easy step by step – and the adorable photos!
