I have never been a fan of store-bought fondant, especially if it has an almond flavor to it! Marshmallow fondant is SO MUCH BETTER and made with only marshmallows, powdered sugar and water. That’s it! Just like our marshmallow fluff, this fondant recipe is also a great way to cover cakes.

Considering most people like marshmallows, this three-ingredient fondant is easy to make, just takes some kneading and a little mess which can be cleaned up.
