To prepare the crust:
Pre-heat oven to 350 degrees.
Place 20 Oreos including filling in the food processor and mix until fine like sand.
Place the Oreos in a bowl and mix with melted butter.
Place a circle of parchment paper into the bottom of your springform pan (optional, but makes it easier to cut once done).
Pour the mixture into your springform pan, spread it, and press evenly.
Place the crust in the oven and bake it for 8 minutes.
Remove the crust from the oven and sit the pan to the side and allow it to cool.
To prepare the cheesecake filling:
Mix the cream cheese and 1 ½ c of sugar until well blended.
Add the sour cream and vanilla.
Mix the ingredients together until blended.
Add the eggs one at a time, mixing well after each addition.
Using a spatula, mix in the crushed and chopped Oreos.
Wrap the springform pan in foil (see video for instructions).
Pour the filling into the pan and smooth the top of the cheesecake.
Place the pan in the water bath (see video/post for instructions), then place the cheesecake in the oven and bake for 1 hour.
Remove it from the oven, allow it to cool, and then cover and refrigerate overnight or for at least four hours.
To prepare the white chocolate ganache:
Place the white chocolate chips in a heat-proof bowl.
Heat the heavy cream just until it begins to boil.
Pour the hot cream over the white chocolate chips and allow to sit for 2-3 minutes, without stirring, and then whisk until smooth.
Allow the ganache to cool for about 5-10 minutes to thicken.
Then pour the ganache onto the top of the cheesecake and spread evenly.
To make the whipped cream:
Using a hand or stand mixer, mix the heavy whipping cream, powdered sugar and vanilla on high speed until stiff peaks form.
Pipe the whipped cream onto the cheesecake as you desire.
Finish decorating the cheesecake as desired and then refrigerate until ready to serve.
