Preheat your oven to 325°F (163°C). In a mixing bowl, combine crushed Oreo cookies with melted butter. Mix until crumbs are fully coated. Press mixture firmly into the bottom of a 9-inch springform pan to form an even layer.
Bake the crust in the preheated oven for about 10 minutes. Remove and let cool while preparing the cheesecake filling.
In a large mixing bowl, beat cream cheese and granulated sugar together with an electric mixer until smooth and creamy, about 2-3 minutes. Add eggs one at a time, mixing well after each addition. Add vanilla extract and mix until fully incorporated.
In a separate bowl, whip heavy cream until stiff peaks form. Gently fold whipped cream into cream cheese mixture until no streaks remain for a light and fluffy texture.
Pour cheesecake filling over cooled Oreo crust in springform pan. Smooth the top with a spatula to create an even surface.
Bake cheesecake in the oven for 55-60 minutes or until edges are set and center is slightly jiggly. Turn off oven and crack door, allowing cheesecake to cool slowly for 1 hour.
After cooling in the oven, refrigerate cheesecake for at least 4 hours or overnight for best results.
Before serving, drizzle top of cheesecake with homemade salted caramel sauce and sprinkle coarsely chopped dark chocolate sea salt caramel pretzels over the top for added crunch.
