2 1/4 pounds fondant


  • ¼ cup butter

  • 1 (16 ounce) package miniature marshmallows

  • ¼ cup water

  • 1 teaspoon vanilla extract

  • 2 pounds confectioners' sugar, divided


  1. Place butter in a shallow bowl and set aside.

  2. Place marshmallows in a large microwave-safe bowl and microwave on high to start melting the marshmallows, 30 seconds to 1 minute.

  3. Carefully stir water and vanilla into hot marshmallows; stir until the mixture is smooth. Slowly beat in confectioners' sugar, 1 cup at a time, until you have a sticky dough. Reserve 1 cup confectioners' sugar for kneading. The dough will be very stiff.

  4. 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.

  5. Form the fondant into a ball, wrap it tightly in plastic wrap, and refrigerate, 8 hours to overnight.

  6. To use, allow the fondant to come to room temperature and roll it out onto a flat surface dusted with confectioners' sugar.
