1. Place 1 cup of frosting in a microwave safe shallow dish.

2. Heat in the microwave for 10-12 seconds or until liquid.

3. Dip the top of each cookie until covered. Let sit at room temperature for 1-2 hours or until the surface is firm and dry to the touch. This will give you your white canvas base.

4. Mix one or two drops of food coloring with two teaspoons of water in a small dish. Use a separate dish for each color.

5. You can add more water or color to achieve the right shade. Mix with a toothpick until no clumps remain.

6. Paint your cookies using clean paint brushes.

7. Let them dry for roughly 1 hour or until the cookies are dry to the touch.
