Step 1: Melt the marshmallows in the microwave.

Step 2: Pour about half the powdered sugar in the melted marshmallows and mix in with a greased spatula.

Step 3: Grease the countertop and your hands with shortening.

Step 4: Knead the mixture while adding the remaining powdered sugar. If it starts to tear rather than stretch, add a tsp of water and continue mixing.

Step 5: Once fully mixed, your fondant is ready to be rolled out and used. Or it can be stored in the fridge for a few weeks. If storing, grease it and bag it.
