Preheat your oven to 350 degrees F. Line the bottom of a 7 inch springform pan with a parchment paper.
Mix your oreo crumbs with your melted butter. Add the crumbs to your prepared springform pan and firmly pat down to get an even layer on the bottom and sides. Bake for 8 to 10 minutes. Set aside.
Fill a deep baking dish with water and carefully place it on the bottom rack of your oven.
Cheesecake:
Mix your instant coffee granules into 1 tbsp of hot water, it does not need to fully dissolve but this helps the process. Set aside.
Reduce your temperature to 325 degrees F. Using a stand mixer with a paddle attachment, beat your cream cheese, sugar, heavy cream, sour cream, vanilla, and salt until smooth. Scrape down the sides of your bowl. Mix in your coffee/water mixture. Add in your eggs one at a time, mixing until the egg is just combined.
Bake at 325 degrees F for 75 minutes. Turn off the oven and slightly crack open the oven door. Let the cheesecake slowly reduce in temperature for one hour then remove it from the oven.
Allow your cheesecake to cool to room temperature and then place in your fridge for at least 4 hours. Once done chilling, slice and enjoy!
