Lightly spray a 9-inch springform pan with cooking spray and set aside. This helps in easy removal of the cheesecake after it sets.
Place the OREOs in a food processor and pulse until only fine crumbs remain. The texture should resemble sand. Drizzle in the melted unsalted butter and pulse several times until completely incorporated; this mixture will be the base of your crust.
Transfer the crumbs to the springform pan and press firmly into the bottom and evenly up the sides of the pan. Ensure there are no gaps, as this will hold the cheesecake filling. Refrigerate for 30 minutes until the crust is firm.
Melt the semi-sweet chocolate chips together with the heavy whipping cream in a small saucepan over low heat. Stir until smooth and no lumps remain, creating a silky ganache.
Pour the ganache over the cooled crust and spread evenly with an offset spatula. The ganache will add a rich flavor and a beautiful sheen.
Refrigerate for at least 30 minutes to set the ganache.
Beat another cup of heavy whipping cream until stiff peaks form. Set aside; this whipped cream will lighten the filling.
In a separate bowl, beat the cream cheese for 2 to 3 minutes on medium-high speed until light and fluffy. It should be creamy and free of lumps.
Beat in the powdered sugar until no lumps remain; the mixture will become even sweeter and creamier.
Beat in the sour cream until nice and creamy, blending all the flavors together seamlessly.
Gently fold in the whipped cream and strawberry preserves, careful to keep the mixture airy and fluffy. You want this to be light and full of flavor.
Pour the cheesecake filling into the springform pan and spread into an even layer. Cover with plastic wrap and refrigerate for at least 4 hours or until the cheesecake is firm.
As the cheesecake sets, melt the semi-sweet chocolate chips together with the heavy whipping cream in a small saucepan over low heat. Stir until smooth.
Drizzle the ganache over the top of the cheesecake, creating a beautiful finish. Top with fresh strawberries and keep refrigerated until ready to serve. This adds an inviting touch and a burst of freshness.
