Preheat the Oven: Set your oven to 350°F (175°C). Line two baking sheets with parchment paper for easy cleanup and to prevent sticking.
Prepare the Ricotta Mixture: In a medium-sized mixing bowl, combine the ricotta cheese, powdered sugar, vanilla extract, lemon zest, and ground cinnamon. Use a whisk or handheld mixer to blend until the mixture is smooth and creamy, ensuring all ingredients are well incorporated.
Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt until evenly mixed. Gradually add the dry mixture into the ricotta blend, stirring gently until just combined – be careful not to overmix.
Add Chocolate Chips: Gently fold in the mini chocolate chips, ensuring they are evenly distributed throughout the dough without breaking up too much.
Shape the Cookies: Using a tablespoon, scoop out portions of the dough and place them onto the prepared baking sheets, leaving adequate space (about 2 inches) between each ball to allow for spreading while baking.
Flatten Slightly: Lightly press down on each cookie ball to flatten them slightly so they bake evenly.
Brush with Egg Wash: Using a pastry brush, coat the tops of the cookies with the beaten egg to achieve a beautiful golden color as they bake.
Decorate with Extra Chocolate Chips: Sprinkle a few additional mini chocolate chips on each cookie for an appealing presentation.
Bake: Place the baking sheets in the preheated oven and bake for 12-15 minutes, or until the edges of the cookies are lightly golden and the centers are set.
Cool and Garnish: Once baked, remove the cookies from the oven and allow them to cool on a wire rack. Before serving, generously sprinkle the chopped pistachios on top for added texture and flavor.
Notes
Serve on a decorative platter and drizzle with melted chocolate for extra decadence.
