This recipe came with my KitchenAid stand mixer. It's easy as can be...if you have a powerful stand mixer. Otherwise, I think you would need a really, really strong mixing arm and I'm pretty sure I would not attempt it.
1 3-ounce package of light cream cheese
1/4 tsp. peppermint extract
2 drops food coloring (as you can see, I used red and green)
4 1/4 to 4 1/2 cups confectioner's sugar
Mix cream cheese, extract and food color is mixer bowl just til smooth (30 seconds or so).
Keeping mixer on low speed, gradually add the confectioner's sugar and mix until very thick (at least 90 seconds).
Shape teaspoonfuls of the mixture into small balls and roll in the superfine sugar. (It's like playing with play dough. My grand son would love it.) Press flat with fingers or a fork to form patties.
Refrigerate, tightly covered.
