Prepare the Crust: Preheat your oven to 325°F (160°C). In a medium bowl, mix the Oreo cookie crumbs and melted butter until well combined. Press the mixture firmly into the bottom of a 9-inch springform pan to form an even crust. Bake for about 10 minutes, then remove and let cool.
Make the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese with an electric mixer on medium speed until creamy and smooth. Gradually add the granulated sugar, mixing until fully incorporated.
Add Flavorings: Mix in the vanilla extract, eggs (one at a time), and sour cream, continuing to beat on low speed until just combined. Be careful not to overmix.
Incorporate Color and Flavor: Sift the cocoa powder into the mixture, then add the red food coloring. Blend until the color is even and a rich red hue is achieved.
Combine with Oreo Crumbs: Gently fold in the crushed Oreos to the cheesecake mixture, ensuring they're evenly distributed throughout.
Bake the Cheesecake: Pour the cheesecake filling over the cooled crust in the springform pan. Smooth the top with a spatula. Bake in the preheated oven for about 45-50 minutes, or until the edges are set but the center still has a slight jiggle.
Cool Down: Turn off the oven and crack the door open, allowing the cheesecake to cool slowly in the oven for about 1 hour. Afterward, remove from the oven and let it cool to room temperature. Then, refrigerate for at least 4 hours or overnight.
Serve: Before serving, top the cheesecake with whipped cream and sprinkle the crushed Oreos over the top. Garnish with fresh mint leaves for a touch of color.
