Crush or process graham crackers until fine and mix with remaining crust ingredients. Press into a 9-10 inch foil lined springform pan evenly and up the sides. Bake at 375 for 8 minutes. Remove and set aside.
Cream together (stand mixer reccomended) sugar and cream cheeses. Add eggs/yolk one at a time until incorporated and fluffy. Add ricotta, sour cream, vanilla, flour, cornstarch, and splenda, blend well. Pour in mini chips and stir until incorporated.
Spread evenly into prepared crust. Set in oven on middle rack. Bake at 400 degrees farenheit for 40 minutes. Reduce to 300 and continue baking until 2 inches away from the center is no longer liquid-y.
Meanwhile, make the ganache.
Either use double-boiler method or microwave (for microwave, heat heavy cream until steaming and stir in chocolate with mixing spoon. Mix until chocolate is completely melted) and set aside.
Once the cheesecake is done, remove from the oven and let cool for 5 minutes. Spread ganache over cheesecake and cover with foil. Let cool in fridge for 7-10 hours before eating. Enjoy.
