Preheat oven to 350 degrees Fahrenheit. Combine all ingredients to form dough and crumb topping.
Place two thirds of the mixture in a 9 1/2 inch springform pan. Press down to form an even crust. Bake until golden, approximately 25 minutes. Remove from oven and allow to cool.
Bake remaining third of crumbs in separate pan for 25 minutes. Remove crumb topping from pan and reserve in a plastic bag. Crush to form fine crumbs. Set aside.
Whip heavy cream with sugar. Set aside.
Beat the cheeses, confectioners’ sugar, and vanilla sugar. Combine cheese mixture with heavy cream by hand; folding gently.
Pour mixture over crust in springform pan. Sprinkle with remaining fine crumbs. Refrigerate for at least 12 hours.
