DIY 3 Ingredient Marshmallow Fondant Recipe and Tutorial from Mandy’s Recipe Box. 4 ingredients if you count the food coloring. This is such a good DIY because you are walked through making this recipe and then the cake decorating by someone who has never done it before and she comes up with this polka dot cake with fondant (there is also a photo at the link of what a cake decorator can do with marshmallow fondant).
