Preheat oven to 425°F (220°C).
Lightly flour a work surface and unroll both pie crusts.
Sprinkle the pie crusts evenly with turbinado sugar and cinnamon.
Gently roll over the dough with a rolling pin to press the sugar and cinnamon into the crust.
Using a 2½-inch round cookie or biscuit cutter, cut circles from the dough.
Press each circle into ungreased mini muffin tin cups.
Re-roll scraps as needed until approximately 48 pastry circles are formed.
Bake for 10 minutes or until golden brown.
Cool in the pan for 15 minutes, then transfer to a wire rack to cool completely.
Meanwhile, prepare the Mini Cannoli Cups filling by beating ricotta, powdered sugar, granulated sugar, citrus zest, and vanilla until smooth and creamy.
Transfer filling to a large zip-top bag and refrigerate until ready to serve.
Just before serving, snip a corner from the bag and pipe about 1 tablespoon of filling into each cooled pastry cup.
Garnish with mini chocolate chips or chopped pistachios.
Dust lightly with powdered sugar and serve immediately.
