Perhaps in tribute to my absolute favorite part of this recipe, it should be called Triple Chocolate Cheesecake. Because the chocolate-hazelnut crust is a different chocolate flavor from the cake itself, or the ganache topping. And this crust is to - die - for! Seriously, I could just spoon it up and eat it by itself. (Or it could make a really nice ice-cream topping.)

CRUST:
2 cups Nabisco Famous Wafer crumbs
1 cup hazelnuts, toasted
1 Tbsp. sugar
1/4 cup melted butter
FILLING:
10 oz. white chocolate
1/2 cup + 2 Tbsp. sugar
5 large eggs
5 Tbsp. heavy whipping cream
5 Tbsp. sour cream
2 Tbsp. flour
1 1/2 tsp. vanilla
GANACHE TOPPING:
12 oz. dark chocolate, finely chopped (no pieces bigger than 1/4-inch)
1 cup heavy cream
Line the bottom of a 9 to 10-inch springform pan with foil; tuck foil
underneath pan bottom, assemble pan, then tighten the foil up the sides of the pan. Cut a circle of parchment paper, the size of the pan bottom, and place in the bottom of the pan. Spray lightly with cooking spray.For the crust: In food processor, blend crumbs, nuts and sugar until hazelnuts are ground fine. Add butter and combine well. Press into bottom and halfway up sides of prepared pan. Bake at 325-degrees for 10 minutes. Remove from oven and set aside to cool.
For the filling: In a large bowl, beat the cream cheese until light and fluffy. Add sugar and beat in eggs, one at a time, beating well after each addition. Beat in the flour and the vanilla.
In a separate bowl, melt the white chocolate; stir until smooth. In a slow stream, add the melted chocolate to the cream cheese mixture, beating, until filling is well combined.
Pour the cream cheese mixture into the crust. Place the cheesecake into a roasting pan [actually I use my deep-dish pizza pan]. Set the roasting pan in the oven and pour in enough boiling water to come halfway up the outside of the springform pan. Bake for about one hour--until a thin knife comes out pretty darn clean. Turn off the heat and keep the oven door ajar, leaving the cake in the oven for one more hour.
Remove the pan from the water bath and fold the foil down away from the sides of the pan. Place on a cooling rack and let cake cool to room temperature.
Now you can put it into the fridge.
For the topping: Place the chocolate pieces in a medium, heat-proof bowl. Heat the cream in a small saucepan over medium heat, but do not let it boil. Immediately pour the hot cream over the chocolate pieces. Tap the bowl on the counter to settle the cream into the chocolate, then let it sit for 1 minute. Using a rubber spatula, slowly stir, being careful not to incorporate a lot of air into the ganache. Stir until all the chocolate is melted, about 2 minutes.
Let the ganache cool--so it's cool to touch, but not set-up.
Do not remove the sides from the springform pan until the cake is topped, and the ganache has a chance to set up!
Pour ganache over the top of the cooled cheesecake; spread evenly.
Refrigerate until the topping is set (give it a couple of hours), then remove the springform sides. Return to refrigerator until 1/2 to 1-hour before serving.
Thoroughly decadent!
