Preheat oven to 375°F (190°C). Grease and flour a mini muffin tin.
In a medium bowl, whisk together the flour, granulated sugar, and salt.
Cut in the cold butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs.
Gradually add the ice water, 1 tablespoon at a time, mixing until the dough just comes together. Do not overmix.
Turn the dough out onto a lightly floured surface and gently form it into a disc. Wrap in plastic wrap and chill for at least 30 minutes.
Roll out the chilled dough to about 1/8-inch thickness. Use a round cookie cutter (about 2.5 inches in diameter) to cut out circles.
Gently press each circle of dough into the greased mini muffin cups, pressing it up the sides.
Bake for 12-15 minutes, or until golden brown and slightly puffed. Let cool in the tin for a few minutes before transferring to a wire rack to cool completely.
While the cups are cooling, prepare the filling. In a medium bowl, combine the drained ricotta cheese, powdered sugar, and vanilla extract. Mix until smooth.
Gently fold in the mini chocolate chips and chopped candied orange peel (if using).
Once the cannoli cups are completely cooled, spoon or pipe the filling into them. Garnish with extra chocolate chips or a dusting of powdered sugar if desired.
Notes
For best results, make sure your ricotta cheese is drained very well to avoid a watery filling. These are best served fresh, within a few hours of filling.
