Preheat oven to 350° F. Line baking sheets with parchment paper.
In a large bowl, beat butter and sugar together until light and fluffy, about 2 minutes.
Beat in the egg. Mix in ricotta, vanilla extract, and orange zest until smooth.
In a separate bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon. Gradually add to the wet mixture and stir until just combined.
Fold in the mini chocolate chips.
Drop rounded portions of dough onto prepared baking sheets using a 2 tablespoon cookie scoop, spacing about 2 inches apart.
Bake for 12 to 14 minutes, until the edges are set and the centers look slightly springy. The cookies will not brown much on top.
Let cool completely on the baking sheet before transferring.
Garnish with powdered sugar, extra mini chocolate chips, chopped pistachios, or a drizzle of melted chocolate before serving.
