Marshmallow Fondant Recipe

Place the butter in a shallow bowl and set aside.

Place the marshmallows in a large microwave-safe bowl and microwave on High for 30 seconds to 1 minute to start melting the marshmallows. Carefully stir the water and vanilla extract into the hot marshmallows and stir until the mixture is smooth. Slowly beat in the confectioners' sugar a cup at a time until you have a sticky dough. Reserve 1 cup of powdered sugar for kneading. The dough will be very stiff.

Rub your hands thoroughly with butter and begin kneading the sticky dough. As you knead the dough will become workable and pliable. Turn the dough out onto a working surface dusted with confectioners' sugar and continue kneading until the fondant is smooth and no longer sticky to the touch 5 to 10 minutes.

Form the fondant into a ball wrap it tightly in plastic wrap and refrigerate overnight. To use allow the fondant to come to room temperature and roll it out onto a flat surface dusted with confectioners' sugar.
