Combine cream cheese and butter in a large mixing bowl and mix until smooth.
8 ounces cream cheese,, 4 tablespoons salted butter
Add 1 cup of powdered sugar and mix until smooth.
2 pounds powdered sugar
Add the mint extract and mix until combined.
½ to 1½ teaspoons mint extract
Gradually, add the remaining powdered sugar until smooth and consistent. You can do this with a stand mixer, hand mixer, food processor or by hand. The dough will get quite stiff towards the end.
Separate the mixture into four separate bowls, or however many different colors you want.
Add a small amount of food color to each bowl and stir in until the color is uniform.
gel food coloring
Cover and refrigerate for 2 hours or until firm enough to handle. You don't want it sticking to your hands.
Line two quarter sheet pans with parchment paper and liberally dust with powdered sugar. Set aside.
Pinch off small amounts of the dough and form into a 1-inch balls.
Roll each ball in powdered sugar and place on prepared sheet pans.
½ cup powdered sugar
Gently press the tines of a fork into the top of each ball. (You can also use the bottom of a shot glass if you don't want the lines. Just dip the bottom of the glass into powdered sugar to keep it from sticking.)
Let stand, uncovered, for at least 4 hours or until the mints are firm. If the bottoms have any moisture, flip over and let stand again until the bottoms of the mints are also firm.
