Instructions

1. Preheat oven to 475 degrees.
2. Create a water bath by placing a large pan filled with about 1/2-inch of water into the oven while it preheats.
3. Combine the raspberry preserves with 1/4 cup water in a medium microwave-safe bowl. Heat for 1 1/2 minutes on high in your microwave. Stir until smooth. Strain to remove the raspberry seeds, then let the strained preserves sit to the side to cool.
4. Measure 1 1/2 cups chocolate cookie crumbs into a medium bowl. Mix in 1/3 cup melted margarine. Press the crumb into a 9-inch spring form pan that has been lined on the bottom and side with parchment paper. Use the bottom of a drinking glass to press the crumb mixture flat into the bottom of the pan and about 2/3 the way up the side.
5. Wrap a large piece of foil around the bottom of the pan to keep the cheesecake in the water bath. Put the crust in your freezer until the filling is done.
6. Use an electric mixer to combine the cream cheese with the sugar, sour cream, and vanilla. Mix for a couple minutes or until the ingredients are smooth and creamy. Be sure to scrape down the sides of the bowl. Whisk the eggs in a medium bowl and then add them to the cream cheese mixture. Blend the mixture just enough to incorporate the eggs.
7. Remove the crust from the freezer and sprinkle 4 ounces of white chocolate chunks onto the bottom of the crust.
8. Pour half of the cream cheese filling into the crust. Drizzle the raspberry preserves over the entire surface of the filling. Use a butter knife to swirl the raspberry into the cream cheese. Pour the other half of the filling into the crust.
9. Carefully place the cheesecake into the water bath in the oven. Bake for 12 minutes at 475 degrees, then turn the oven down to 350 degrees and bake for 50 to 60 minutes or until the top of the cheesecake turns a light brown or tan color.
10. Remove the cheesecake from the oven to cool. When the cheesecake is cool, use the foil from the bottom to cover the cheesecake and chill it in the refrigerator for at least 4 hours.
11. Before serving, sprinkle the entire top surface of cheesecake with 2 ounces of shaved white chocolate.
