Blackberry Cheesecake Recipe

Directions

Preheat oven to 300° degrees F. Combine crumbs, sugar, cinnamon and butter.  Press onto bottom of springform pan.  A little oil on your fingers helps to keep the crust from sticking to your fingers. 

Blend in cream cheese and add eggs one at a time, whipping after each addition.  Gradually add sugar and mix. 

Pour over crust.  Bake 45 minutes.  Remove from oven and place on a wire rack. 

Whip sour cream, sugar and vanilla.  Pour on top of baked cake and bake for 10 more minutes. 

Remove and chill until firm.  When ready to serve, heat jam and blackberries.  Pour hot over the cake slices or entire cake.  Serve your Blackberry Cheesecake Recipe.
