• Preheat the oven to 350 degrees F

Crust

• Line a 9x9 inch baking dish with parchment paper.
• Break cannoli shells up into smaller pieces, then add to a food processor and pulse until they became crumbs. Pour the crumbs into a separate bowl and add in the melted butter and sugar and mix until ingredients are combined together. Press mixture into the bottom of the prepared pan.
• Bake crust for 8 minutes in the preheated oven.

Filling

• Mix the cream cheese and ricotta cheese together in a mixing bowl until well combined. Stir in the sugar, eggs, vanilla, orange zest, and cinnamon. Pour the mixture into the prepared pan over the crust. Sprinkle chocolate chips over batter.
• Bake in the preheated oven for 1 hour until the edges are golden brown and the center is set. Cool, then refrigerate for at least 4 hours. Sprinkle powdered sugar over bars before serving if preferred.
