Process the cookies in a food processor until they're cookie crumbs.
Combine the cookie crumbs with the melted butter, and press the mixture into the mini pie pans.
Combine the cream cheese, powdered sugar, whipped topping and mint oil in a medium mixing bowl.
Pour the cheesecake mixture over the top of the cookie crumb mixture and put the pan into the refrigerator to chill for several hours.
Remove the mint mini cheesecakes from the oven just before you're ready to serve them and sprinkle crushed mint candies over the top.
Cut the mini cheesecakes into about 4 slices and add them to your holiday dessert buffet.
