Marshmallow Fondant

Kiele Briscoe

"This is a very easy (and a little sticky at times) way to make a delicious fondant. It's great on cakes, cookies, or just for your little ones to play with! Leftovers will save in a tightly sealed container for a few weeks."

  1. Place the butter in a shallow bowl, and set aside.
  2. 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.
  3. 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.
  4. 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.


  • Tip
  • Aluminum foil can be used to keep food moist, cook it evenly, and make clean-up easier.
