Combine milk, cream, powdered sugar, mint extract, and green food coloring in a large glass mixing bowl with a spout. Stir until powdered sugar is completely dissolved.
Crumble Thin Mints into mixture, leaving some larger pieces according to taste.
Fill popsicle molds or small paper cups with mixture (*note: if using small paper cups, you will need to wait until mixture is partially set to insert popsicle sticks.)
Freeze until firm.
To remove, place popsicle molds in lukewarm water until popsicles become loosened from the sides of the molds.
