Beat the cream cheese on medium speed until light and creamy with a stand mixer or hand mixer.
Next, add the heavy cream. Beat on medium speed until the mixture has thickened.
Add ricotta cheese, powdered sugar and cinnamon. Mix until well combined but do not overmix.
Fold in chocolate chips by hand until combined.
Spread the filling into the graham cracker pie crust.
Refrigerate for at least 4 hours but overnight is best. This gives the flavors time to blend and the filling to set fully.
When ready to serve, prepare the topping. Beat the heavy whipping cream with a hand held mixer or stand up mixer until stiff peaks form.
Mix in the powdered sugar and vanilla. Mix until combined.
Serve each slice topped with the whipped cream and mini chocolate chips. Enjoy!
