Using a blender or small food processor, pulse 10 oreos until you have crumbs. Evenly divide the crumbs among 4 glasses.
In a mixing bow, combine the softened cream cheese and sugar. Beat until fluffy with an electric mixer. Add in the peppermint extract and cool whip, mix again until combined. Add in a few drops of green food coloring and mix using a spatula, not the mixer.
Refrigerate the cheesecake mixture in the mixing bowl for 30 minutes.
After 30 minutes, spoon or pipe using a piping bag the cheesecake mixture into the glasses.
