1 (10oz) package frozen raspberries
2 tablespoons sugar
2 teaspoons cornstarch
1/2 cup water
25 oreos, crushed
1/4 cup melted butter
2 cups chopped white chocolate (the best quality you can find!)
1/2 cup half & half
3 (8oz each) packages cream cheese, softened
1/2 cup sugar
3 large eggs
1 teaspoon vanilla
1/4 teaspoon salt
2 regular sized Hershey bars, milk or dark chocolate, coarsely chopped
1/2 cup heavy cream
1 cup chocolate chips or chopped dark chocolate
Make the raspberry sauce: Stir together the raspberries, sugar, cornstarch and water in a medium saucepan. Bring to a boil, stirring occasionally, and boil 5 minutes. Pour through a fine-mesh strainer into a small bowl and store in the fridge until you are ready to make the cheesecake. (This step can be done a few days in advance!)
Make the crust: Preheat the oven to 350ºF. Stir together the finely crushed oreos and melted butter in a medium bowl until well mixed. Press into the bottom of a Springform pan and bake for 10-15 minutes, until the crust is set. Remove from the oven, reduce the oven temperature to 325ºF and let the crust cool while you prepare the filling.
Make the filling: In a medium saucepan, heat the half & half to almost simmering. Remove from the heat and stir in the white chocolate until melted and smooth. Set aside.
In a large bowl, beat together the cream cheese and sugar until smooth. Beat in the eggs, one at a time, making sure to blend completely after each one. Beat in the vanilla, salt and the melted white chocolate mixture.
Wrap the pan with the cooled crust in it tightly with foil. Place the foil-wrapped pan in a roasting pan, and put a pot of water on the stove to boil (you will be making a water-bath for the cheesecake to bake in).
Pour half of the filling over the crust. Sprinkle with the chopped Hershey’s bars. Drizzle 4-5 tablespoons of raspberry sauce over the filling and chocolate bits and swirl with the tip of a knife. Pour the rest of the filling on top of that, drizzle with another 4-5 tablespoons of the raspberry sauce and swirl again with the knife.
Place the roasting pan into the oven and pour water into the roasting pan to reach about halfway up the sides of the Springform pan. Bake the cheesecake at 325ºF for 60-70 minutes, until the center is almost set (but still jiggles if you shake the pan).
Remove the roasting pan from the oven, let the cheesecake sit in the hot water for another 30 minutes or so, and then remove the Springform pan from the water onto a cooling rack to cool. Let the cheesecake cool to room temperature and then place in the fridge to chill at least 3 hours.
Make the ganache: In a small saucepan, bring the heavy cream just to a boil. Remove from the heat and stir in the chocolate until smooth. Pour the ganache over the top of the cooled cheesecake, smoothing with a spoon and allowing some of the ganache to drip over the sides of the cheesecake. Return to the fridge to chill an additional 3 hours or until the ganache is shiny and set.
At this point you can wrap the cheesecake tightly in foil and freeze for several months, if desired! Cheesecake is a great make-ahead dessert, as it only tastes better as it chills. If frozen, remove from the freezer and thaw in the fridge for a few hours before serving!
