Lightly grease the bottom and sides of a 9-inch springform pan with non-stick spray. Mix together the Oreo baking crumbs and melted butter and press into the bottom of the pan to form a crust. Refrigerate while making the filling.
To make the Filling:
Whisk together the boiling water and raspberry Jello until fully dissolved. Let cool to room temperature (but do not refrigerate or allow to set).
Place the softened cream cheese and powdered sugar in a large mixing bowl and beat with an electric handheld mixer, starting on low and increasing to highspeed for 2 minutes or until fluffy and smooth. Add the vanilla extract and lemon juice and mix until incorporated.
Next, add the room temperature Jello mixture and mix at low speed until combined. Lastly, add the whipping cream and mix, starting at low speed and increasing to high as the mixture comes together. Beat at high speed for 1 minute or until fluffy and slightly thickened (it will still be quite runny but it will set in the fridge). Pour into the pan over the prepared crust and tap the pan on the counter a few times to release air bubbles.
Cover and refrigerate for at least 4 hours or until set before serving. Serve with whipped cream and fresh raspberries, if desired. Enjoy!
Notes
You may use Oreo chocolate cookie crumbs instead to make the crust for this recipe. Crush up just the cookies without the icing if using Oreos.
Unsalted butter works instead in the crust. Add ¼ teaspoon of salt to the butter in the crust if you like a salty/sweet-tasting crust.
Mix the jello powder with boiling water until fully dissolved. Then, allow the mixture to cool at room temperature until it is only slightly warm before adding to the cheesecake batter. Don't let the jello mixture cool for too long because it will start to set and you will end up with lumps of jello in the cheesecake batter
Fresh or bottled lemon juice works here. You have to mix the lemon juice in with the cream cheese and sugar. It must be incorporated before the jello mixture is added so that it doesn't interfere with the gelatin.
