These step-by-step instructions will guide you to create the amazing Classic Cannoli Squares effortlessly:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and line an 8×8 inch baking pan with parchment paper.

2. Make the Cannoli Shell Crust: In a bowl, combine the crushed cannoli shells or graham cracker crumbs, all-purpose flour, sugar, salt, cinnamon, and softened butter. Mix until crumbly.

3. Press the Crust: Press the mixture evenly into the bottom of the prepared baking pan. This will form the crust for your squares.

4. Bake the Crust: Place the pan in the preheated oven and bake for about 10 minutes or until lightly golden. Remove from the oven and set aside to cool.

5. Prepare the Filling: In a mixing bowl, combine the ricotta cheese, powdered sugar, vanilla extract, almond extract, and mini chocolate chips. Blend until smooth and creamy.

6. Spread the Filling: Once the crust has cooled, evenly spread the ricotta filling over the crust using a spatula.

7. Bake Again: Return the pan to the oven and bake for an additional 20 minutes, or until the filling is set and slightly golden on top.

8. Cool Completely: Allow the pan to cool at room temperature for about 1 hour. Then, refrigerate for at least another hour to ensure the filling has set properly.

9. Slice the Squares: Once cooled and set, lift the dessert from the pan using the parchment paper overhang. Slice into squares.

10. Dust and Serve: Before serving, dust the squares with additional powdered sugar for a beautiful finish.
