Prepare the Crust: Preheat your oven to 325°F (160°C). In a medium-sized bowl, thoroughly combine the Oreo cookie crumbs with the melted butter, ensuring that all crumbs are evenly coated. Firmly press this mixture into the bottom of a 9-inch springform pan to create a solid, even crust. Place the pan in the oven and bake for approximately 10 minutes. Once done, remove it from the oven and allow it to cool completely.
Make the Cheesecake Filling: In a large mixing bowl, use an electric mixer on medium speed to beat the softened cream cheese until it achieves a creamy and smooth consistency. Gradually add the granulated sugar, continuing to mix until fully combined and there are no lumps.
Add Flavorings: Add the vanilla extract to the cream cheese mixture. Then, introduce the eggs one at a time, mixing on low speed after each addition until just combined. Finally, mix in the sour cream gently, taking care not to overmix the ingredients.
Incorporate Color and Flavor: Sift the unsweetened cocoa powder into the cheesecake filling and add the red food coloring. Blend the mixture until the color is uniformly distributed, resulting in a rich red hue throughout.
Combine with Oreo Crumbs: Gently fold the crushed Oreos into the cheesecake mixture using a spatula, ensuring they are evenly spread out within the batter.
Bake the Cheesecake: Carefully pour the cheesecake filling over the cooled crust in the springform pan. Use a spatula to smooth the surface. Bake in the preheated oven for 45 to 50 minutes, or until the edges are set and only the center has a slight jiggle when gently shaken.
Cool Down: After baking, turn off the oven and crack the door open to allow for a slow cooling process. Let the cheesecake cool in the oven for about 1 hour. Once the hour is up, remove it from the oven and let it cool completely to room temperature. Once cooled, refrigerate the cheesecake for at least 4 hours or preferably overnight to set firmly.
Serve: Just before serving, generously dollop the cheesecake with whipped cream and sprinkle the crushed Oreos on top for a crispy finish. Add fresh mint leaves as a vibrant garnish to enhance the presentation.
Notes
For best results, refrigerate overnight to allow the cheesecake to set firmly.
