This is an easy and VERY tasty recipe! I used this for the Baby Shower Cake and everyone thought it tasted great!
16 ounces white mini-marshmallows (use a good quality brand)
2 to 5 tablespoons water
2 pounds icing sugar (please use C&H Cane Powdered Sugar for the best results)
1/2 cup Crisco shortening (you will be digging into it so place in a very easily accessed bowl)
Melt marshmallows and 2 tablespoons of water in a microwave or double boiler: Put the bowl in the microwave for 30 seconds, open microwave and stir, back in microwave for 30 seconds more, open microwave and stir again, and continue doing this until melted. It usually takes about 2 1/2 minutes total. Place 3/4 of the powdered sugar on the top of the melted marshmallow mix.
Now grease your hands GENEROUSLY (palms, backs, and in between fingers), then heavily grease the counter you will be using and dump the bowl of marshmallow/sugar mixture in the middle.
Start kneading like you would bread dough. You will immediately see why you have greased your hands. At this stage, you will swear this is a huge mistake, but hang in there!
Keep kneading, it will continue to be VERY stickey. Add the rest of the powdered sugar and knead some more. Re-grease your hands and counter when the fondant starts sticking. If the mix is tearing easily, it is to dry, so add water (about 1/2 tablespoon at a time and then knead it in). It usually takes me about 8 minutes to get a firm smooth elastic ball so that it will stretch without tearing when you apply it to the cake.
It is best if you can let it sit, double wrapped (in saran wrap), overnight (but you can use it right away if there are no tiny bits of dry powdered sugar). If you do see them, you will need to knead and maybe add a few more drops of water.
Prepare the fondant icing for storing by coating it with a good layer of Crisco shortening, wrap in a plastic-type wrap product and then put it in a re-sealable or Ziploc bag. Squeeze out as much air as possible.
This marshmallow fondant icing will hold very well in the refrigerator for weeks. Take advantage of the fact that this fondant icing can be prepared well in advance!
