Line 3 rimmed cookie sheets or baking sheets with parchment paper or wax paper. Set aside.
Place 1/2 cup of the powdered sugar in a small bowl, and set it aside for later.
In a large bowl with a hand or stand mixer, beat the cream cheese and butter until creamy, fluffy, and well whipped. About 2 minutes.
1 bar (8 oz) full-fat cream cheese, 3 tablespoons salted butter
Add 4 cups of powdered sugar, peppermint extract, and vanilla extract and beat until combined and smooth.
1½ teaspoons peppermint extract, ¼ teaspoon vanilla extract, 8½ cups powdered sugar
Add the remaining 4 cups of powdered sugar, one cup at a time, beating well after each addition until the dough resembles a play dough like consistency.
Divide the dough into 3 equal portions and place each portion in a separate bowl.
Color one portion of the dough green, one portion red, and leave the third portion as white. Cover the bowls with lids or plastic wrap, and refrigerate for at least 2 hours or up to overnight.
red & green gel food coloring
Use a 1 teaspoon measuring spoon to scoop some dough and roll it into a ball. Roll the ball in the powdered sugar (set aside from earlier) until it's well coated. Place the balls onto the prepared baking sheets. Repeat with all the remaining dough.
Dust the tins of a fork with powdered sugar and press the fork into the cream cheese mint balls to flatten them into a coin shape.
Allow the cream cheese mints to dry at room temperature for 3 to 4 hours or until the outside hardens and they lift easily off the parchment paper.*If the bottom of the mints are still damp, turn them over and allow them to continue to dry at room temperature. I prefer serving the cream cheese mints chilled but you can also serve them at room temperature (but they do get softer in texture as they sit out).Keep the mints stored in the refrigerator, for up to 7 days, in an airtight container.
