Preheat your oven to 350°F (175°C). In a mixing bowl, combine Oreo cookie crumbs with melted butter until well mixed. Press this crumb mixture firmly into the bottom of a greased springform pan to create a solid base. Bake the crust in the preheated oven for 10 minutes until set and golden; then allow it to cool completely before proceeding.

Prepare your red velvet cake batter following the package instructions or your favorite recipe. Once mixed, carefully pour the batter over the cooled Oreo crust in the springform pan. Bake the layered cake in the oven for 25–30 minutes or until a toothpick inserted in the center comes out clean. Let the red velvet layer cool completely on a wire rack before adding the cheesecake layer.

In a large mixing bowl, beat the room temperature cream cheese using a hand mixer until smooth and creamy. Gradually add granulated sugar, vanilla extract, and eggs one at a time, blending well after each addition. Finally, mix in sour cream until fully incorporated, creating a rich cheesecake batter that's ready to be poured over the cooled red velvet layer.

Pour the cheesecake batter gently over the red velvet cake in the springform pan. To prevent cracks, bake in a water bath at 325°F (163°C) for 50–60 minutes, until the edges are set but the center is slightly jiggly. Once done, turn off the oven, crack the door, and let the cheesecake cool gradually for about an hour before transferring to the refrigerator to chill for at least 4 hours, or preferably overnight.

Melt white chocolate chips in a microwave-safe bowl in 30-second intervals, stirring until smooth. Once melted, add red gel food coloring a little at a time, stirring to achieve your desired shade. Allow the mixture to cool slightly until it's pourable but not too hot, ensuring a perfect consistency for the drip.

Remove the chilled Oreo Red Velvet Cheesecake from the springform pan and place it on a serving platter. Carefully pour the prepared red chocolate drip around the edges of the cheesecake, letting it cascade beautifully down the sides. Decorate the top with delightful swirls of whipped topping or buttercream and garnish with whole Oreo cookies to complete your stunning dessert.

Once decorated, slice your Oreo Red Velvet Cheesecake Drip Cake into generous pieces. Serve each slice chilled, enjoying the layers of crunchy Oreo, moist red velvet, and creamy cheesecake.
