Preheat oven to 350°F (175°C). Wrap a 9-inch springform pan tightly with heavy-duty aluminum foil to prevent water seepage.

Crush Oreo cookies finely. In a bowl, combine crumbs with melted butter and 2 tablespoons of white sugar. Press mixture firmly into the bottom of the prepared springform pan. Bake for 8-10 minutes. Cool completely on a wire rack.

In a mixer, beat softened cream cheese until smooth. Gradually add ½ cup white sugar, mixing until just combined. Stir in vanilla extract, cocoa powder, and red food coloring until evenly vibrant. In a separate bowl, whip 1 cup of the heavy whipping cream until soft peaks form. Gently fold the whipped cream into the cream cheese mixture until just combined. Fold in ¼ cup Christmas sprinkles. Pour filling over the cooled crust.

Reduce oven temperature to 325°F (160°C). Place the foil-wrapped springform pan into a larger roasting pan. Carefully pour hot water into the roasting pan, reaching halfway up the springform pan's sides. Bake for 1 hour to 1 hour and 15 minutes, or until edges are set but the center still jiggles slightly.

Turn off the oven, leave the cheesecake inside with the door ajar for 1 hour. Remove from oven and water bath; cool completely on a wire rack for 2-3 hours. Run a knife around the edge to loosen, then cover loosely and refrigerate for at least 6-8 hours, preferably overnight, until firm.

Remove springform pan sides. Top cheesecake with whipped cream. Garnish with mini Oreos and extra Christmas sprinkles. For clean slices, use a sharp, hot knife wiped clean between cuts. Store leftovers in the refrigerator.
