Chocolate Chip Cookie Crust:
4 tablespoons flour
2 cups ground chocolate chip cookies
8 tablespoons unsalted butter, melted
1-1/2 pounds cream cheese, at room temperature
3/4 cup sugar
4 ounces chopped white chocolate
4 ounces chopped chocolate chips
chocolate sauce and sweetened whipped cream
For the crust mix all the ingredients in a bowl, then press the mixture into a 9-inch spring-form pan, pressing well to cover the entire bottom and the sides of the pan.
Preheat oven to 325 degrees.
In a large bowl, beat the cream cheese with an electric mixer, until fluffy, about 2 minutes. Beat in the sugar and the eggs one at the time, beating well after each addition. Fold in the chocolate pieces. Pour the batter into the crust and bake for 1-1/4 hour, or until a knife inserted comes out clean.
Remove from the oven. Cool, cover and refrigerate at least 5 hours or overnight. Remove it from the pan and serve with the optional chocolate sauce and whipped cream.
