Mix cream cheese, butter, confectioners sugar, and extract until well-combined and a dough is formed. Roll into small balls. Place on parchment paper. Press each ball with tines of fork dipped in confectioners sugar. Allow to stand at room temperature for 2 1/2 hours. Store in an airtight container and refrigerate up to 2 weeks.
Notes
To make with a cookie press: Make dough as directed and then put dough into cookie press fitted with shape of choice. Press mints onto a baking sheet (without parchment paper!) and allow to dry for 2 1/2 hours. Carefully remove from sheet pan with metal spatula.
