In a large bowl, whisk together flour, baking powder, and salt. Set aside.
To the bowl of a stand mixer fitted with the paddle attachment, add sugar, butter, and orange zest. Mix on medium speed until light and fluffy, about 3-5 minutes.
Add egg. Mix well. Add ricotta and vanilla. Mix until well combined.
Stop the mixer and add the flour mixture. Mix on low until just combined.
Add chocolate chips and mix until just combined.
Cover and chill dough in the refrigerator for 1-2 hours, or until the dough is no longer sticky.
When ready, preheat oven to 350°F. Line 3 large baking sheets with parchment paper.
When the dough is sufficiently chilled, using a 1 tablespoon cookie scoop, drop the dough onto prepared baking sheets, leaving about an inch between each cookie.
Bake for 13-14 minutes, or until almost set.
Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to finish cooling.
While the cookies are cooling, prepare the glaze. In a medium bowl, whisk together confectioners' sugar and fresh orange juice.
Drizzle the glaze over the cooled cookies.
