Follow these steps to create your Pink Oreo Cheesecake:

1. Preheat the Oven: Preheat your oven to 325°F (165°C). This temperature is ideal for baking cheesecakes.
2. Prepare the Crust: In a medium bowl, combine the crushed Oreos and melted butter. Mix until evenly combined. Press the mixture into the bottom of a 9-inch springform pan to form a crust.
3. Bake the Crust: Place the pan in the oven and bake for about 10 minutes. Remove and allow to cool while preparing the filling.
4. Make the Filling: In a large mixing bowl, beat the softened cream cheese until creamy. Add the granulated sugar and vanilla extract, continuing to mix until smooth.
5. Add Whipped Cream: In another bowl, whip the heavy cream and powdered sugar together until stiff peaks form. Gently fold this whipped cream into the cream cheese mixture.
6. Color the Mixture: Gradually add in the pink food coloring, mixing until you achieve your desired shade. Ensure the color is consistent throughout.
7. Combine: If using, dissolve the gelatine in a small amount of warm water and mix it into the cheesecake mixture. This step can enhance the texture.
8. Pour into the Crust: Carefully pour the cheesecake filling over the cooled Oreo crust, spreading it out evenly.
9. Bake: Bake the cheesecake in the preheated oven for 30-35 minutes, or until the edges are set but the center is still slightly jiggly.
10. Cool: Remove the cheesecake from the oven and let it cool at room temperature for about 30 minutes. Then, refrigerate for at least 4 hours, or overnight if possible, to set completely.
11. Remove from Pan: Once chilled and set, carefully remove the cheesecake from the springform pan.
