Chocolate Cheesecake

I found this recipe somewhere on the Internet, but I can’t remember where. All I can remember is that it’s by a guy called Glenn. I’ve changed it slightly (metricised the units, added a little more in-depth explanation). Ingredients Crust 1 1/4 cups chocolate cookie crumbs 1/4 cup melted butter Filling 700g cream cheese 1 cup sugar 3 eggs 1/2 cup sour cream 1 tablespoon vanilla essence 300g chocolate chips Topping 1/2 cup double cream 150g cooking chocolate Method For the crust, mix the cookie crumbs with the melted butter. Press the mix onto the bottom of a 9 inch cake tin. Blind bake the crust in a preheated oven for 5 minutes at 160oC. For the filling, beat the cream cheese and sugar until smooth. Beat in the eggs one at a time, followed by the sour cream and vanilla essence. Stir in the chocolate chips. Pour this mixture over the crust and bake for 45 min or until the cheesecake is set. Turn off the oven, open slightly and leave the cake in the oven for 30 minutes. Remove from the oven and let the cake cool completely. For the topping, bring the cream to a boil over medium heat. Pour this over chopped chocolate (which should be in a mixing bowl) and stir until smooth. Pour this over the top of the cake.
