Chocolate Cheesecake

2 cups graham cracker crumbs

2 tablespoons white sugar

1/3 cup melted butter

1 cup chocolate chips

3 (8 ounce) packages cream cheese, softened

1 cup white sugar

3 eggs

1/2 cup sour cream

3 tablespoons all-purpose flour

2 teaspoons vanilla extract

Prepare crumb crust by combining crackers, butter, and two tsp sugar. Press mixture into bottom and sides of two pie tins (may have to double the crust ingredients). Refrigerate. Melt chocolate chips and set aside. Beat cream cheese and one cup sugar in large bowl until smooth and creamy. Blend in eggs. Gradually pour in chocolate mixture, beating on low speed until well-blended. Add ½ cup sour cream, flour and vanilla. Blend until smooth. Pour into prepared crust. Bake in preheated oven at 350 for 55-60 minutes until filling is firm. Turn off oven and cool cheesecake for one hour without opening the oven door. Cool completely. Chill several hours or overnight.
