Follow these straightforward instructions to create your delicious Lavo Cannoli:

1. Make the Dough:
– In a large mixing bowl, combine the flour, granulated sugar, cocoa powder, and salt.

2. Mix Wet Ingredients:
– In a separate bowl, whisk together the egg yolk, vinegar, and vegetable oil. Gradually add water while mixing until the dough forms.

3. Knead the Dough:
– On a lightly floured surface, knead the dough until smooth and elastic, about 5-7 minutes. Wrap in plastic wrap and let it rest for 30 minutes.

4. Prepare the Cannoli Forms:
– While the dough rests, prepare your cannoli forms by lightly greasing them to prevent sticking.

5. Roll Out Dough:
– After resting, roll out the dough on a floured surface to about 1/8 inch thickness. Cut into circles measuring about 4-5 inches in diameter.

6. Wrap the Forms:
– Carefully wrap each circle of dough around a cannoli form, sealing the edges with a bit of water.

7. Fry the Shells:
– In a deep pot, heat oil to 350°F (175°C). Fry the wrapped dough until golden brown, about 2-3 minutes. Remove and place on paper towels to drain.

8. Cool the Shells:
– Once cooled, gently remove the shells from the forms. Let them cool completely.

9. Prepare the Filling:
– In a large bowl, combine ricotta cheese, powdered sugar, and vanilla extract. Mix until smooth and creamy. Fold in chocolate chips and cinnamon if desired.

10. Fill the Cannoli:
– Using a piping bag or a spoon, fill each cooled shell with the ricotta mixture.

11. Garnish and Serve:
– Dust with powdered sugar and garnish with chopped pistachios or extra chocolate chips as desired.
