In a large bowl, beat the cream cheese until creamy and smooth with a hand mixer. Add the heavy cream and powdered sugar. Mix until there are no lumps.
Add 3 drops of green food coloring, peppermint extract, and vanilla extract into the bowl. Mix together. (You can add more food coloring until your desired color is reached.) Fold in the chocolate chips by hand.
Transfer the cheesecake mixture to a large piping bag with the end cut off. (see note)
Fill six 8-ounce jars or dessert cups 1/4 full with the crushed Oreo cookies. Then lightly press down or shake to flatten the cookie crumbs. Pipe in enough cheesecake cheese mixture to fill the jars halfway. Repeat the layers.
Top the cheesecake jars with any garnishes you like and then serve. If prepared ahead fo time, cover with the jar lid (or plastic wrap) and chill until ready to serve.
Notes
If you don't have piping bags, you can use a food storage bag with one corner cut off. Just be sure the opening is wide enough for the chocolate chips to fit through.
Want to make a whole cake? Mix the crushed Oreos with 4 tablespoons of melted butter. Press the Oreo mixture into a pie plate or cake pan. Cover with the mint chocolate chip cheesecake mixture and spread it into an even layer. Chill in the fridge until the cheesecake is set. Decorate the edges with whipped cream dollops and any other garnish you like before slicing.
