Combine butter and cream cheese in a large mixing bowl and mix together until well combined and smooth.
Add mint and vanilla and mix well.
Gradually add the powdered sugar, and check for consistency of stickiness.
Separate the dough into bowls for however many colors you're using and add the color and stir until desired color is achieved.
Roll into 1" balls and roll into powdered sugar.
Place on a baking sheet that's lined with parchment paper and dip a fork into powdered sugar and flatten the balls using the fork.
Allow to sit out and dry or place baking sheets in refrigerator to dry out before storing in an airtight container. At this point I flash freeze them and then store in a freezer safe bag so they don't stick together.
