Place the 1/4 cup of water in a small bowl, and sprinkle the Envelope of Gelatin on the water.
Let the Gelatin sit while you mix up the cheesecake filling. (This is letting the Gelatin 'Bloom' - it will absorb all the water, and when added to the cheesecake filling, it helps the cheesecake to set).
In the mixing bowl of a stand mixer, place the softened Cream Cheese, Greek Yogurt, and Heavy Cream, and mix on low until blended. Scrap down the sides of the mixing bowl, and mix until smooth.
Add the sugar, Vanilla, and Lemon Juice, and blend on low until well mixed. Scrape down the bowl again, and mix until all ingredients are smooth and creamy.
Add the Gelatin to the mixing bowl, and blend until completely mixed, and smooth.
Crumble two cookies in the bottom of each Parfait cup, and then place the Cheesecake Filling on top of the cookie crumbs, filling the Parfait dishes about halfway full.
Crumble two to three more cookies on top of the Cheesecake Filling, and then fill the Parfait dish with the Cheesecake filling.
Sprinkle the tops of the Parfait's with the Mini Chocolate Chips, and place an Oreo cookie on the side of the Parfait dish.
Place the Parfait's in the refrigerator for at least 4 hours, or overnight for best results.
Serve, and Enjoy!
