Yes, most definitely!
Marshmallow Fondant
16 oz Mini Marshmallows
2-5 tablespoons Water
2 lbs Confectioner's Sugar
1/2 cup Shortening
Melt marshmallows and water (I used 4 tbsp.) in a large microwavable bowl at 30 second intervals. Once melted, place 3/4 of the confectioner's sugar on top of the marshmallows. Grease your hands VERY generously with the shortening. Grease your countertop and dump the marshmallow/sugar mix on your greased surface. (I think if I were to do it again, I would have mixed the sugar a little more into the marshmallow before dumping). CAUTION: Melted marshmallow is extremely hot!
Knead the mixture and gradually add the rest of the bag of sugar or to consistency that isn't too sticky. Knead about 8 minutes. If your fondant is too dry and rips, try adding one tablespoon of water at a time. It is a very messy and sticky ordeal, yes, very sticky!!!
You can use the fondant right away or you may place it in the fridge wrapped in plastic with a layer of shortening placed on it so it doesn't dry out. To make it more workable after refrigeration I microwaved it for 5 seconds.
I had no trouble with my fondant drying out and it came together beautifully, I looked like a professional and this was my first time with fondant!
Good luck to her, I'm sure they will turn out great!
