In Beverly's cookbook called A Family Raised on Sunshine, she gives this recipe for Spring. While it is nice enough just rolled into patties, you can also mold it in a candy mold for pretty shapes.
Knead together with hands*:
8 oz. package cream cheese, room temp
2 lb. package powdered sugar
Color and flavor as desired:
*I use my Kitchen Aid mixer to mix these ingredients.
Either shape into small patties or mold with candy molds. I've seen some candy makers roll these in white sugar immediately after shaping.
You can also just add mint flavoring, form into patties, and dip into dipping chocolate.
