Cookies topped with fondant

This sweet, simple recipe transforms your cookies into a perfect art canvas.

Equipment:

* Large bowl
* Microwave
* Whisk or egg beater
* Rolling Pin
* Cookie cutter or small glass
* Ripple Maker

Ingredients:
  • 1/4 cup unsalted butter
  • 16 oz (1 package) mini marshmallows
  • 1 tsp vanilla extract
  • 32 oz powdered sugar

Instructions:

Step 1:

Place butter in a shallow bowl. Set aside

Step 2:

Place marshmallows in a large microwave-safe bowl, and microwave on high for 30 seconds at a time, until marshmallows are mostly melted.

Step 3:

Carefully stir the water and vanilla extract into the marshmallows, and stir until smooth.

Step 4:

Reserve 1 cup of powdered sugar. Slowly beat in the remaining powdered sugar, one cup at a time, until mixture forms a sticky dough. The dough will be very stiff.

Step 5:

Rub hands with butter, and begin kneading the dough inside the bowl. As you knead, it will become more pliable.

Step 6:

Dust work surface with powdered sugar. Turn out dough, and continue kneading until the fondant is smooth and no longer sticky to the touch, about 5 or 10 minutes.

Step 7:

Shape the fondant into a ball, wrap tightly in plastic wrap, and refrigerate overnight.

Step 8:

To use, allow fondant to come to room temperature. Dust a flat surface with powdered sugar, and roll out dough to desired thickness.

Step 9:

Cut into rounds, print, and top off your favorite cookies to serve.
