In a large bowl using an electric mixer beat the mascarpone cheese for about 10 seconds, add the ricotta cheese and beat on medium speed until well combined and smooth.
16 ounces Mascarpone cheese, 15 ounces Whole milk ricotta cheese
Add the granulated sugar, vanilla, all-purpose flour, cinnamon, orange zest, and kosher salt. Beat until well combined, scraping down the sides of the bowl as needed.
1 1/4 cup Granulated sugar, 3 tbsp All-purpose flour, 1/4 tsp Ground cinnamon, 1 tsp Fresh orange zest, 1 1/2 tsp Vanilla extract, 1/2 tsp Kosher salt
Beat the eggs in one at a time until combined. Toss the chocolate chips with the remaining 1 tablespoon of flour. Fold in 1/4 cup of the chocolate chips.
4 large Eggs, 3/4 cup Mini chocolate chips
Pour half the batter over the cooled crust, and spread it out evenly. Sprinkle 1/4 cup of the chocolate chips on top of the cheesecake batter. Repeat with the remaining batter and remaining chocolate chips.
Place the cheesecake in the roasting pan. Place it in the center of the preheated oven. Slowly pour boiling water into the roasting pan until the water is halfway up the sides of the springform pan.
Bake the cannoli cheesecake for 1 1/2 hours or until light golden brown, the edges are set but still jiggly in the middle. Check the cheesecake after about 70 minutes of baking time. Not all ovens are the same.
Turn the oven off, crack the oven door, and let the cheesecake slowly cool in the oven while still in the water bath for one hour. At this time you can sprinkle a few more chocolate chips over the top of the cheesecake.
Remove the roasting pan from the oven, then carefully remove the springform pan to a wire rack to cool completely to room temperature.When the cheesecake is cooled completely cover the springform pan with a large paper towel and then wrap it tightly in plastic wrap and refrigerate for 6 hours but overnight is best.
