Preheat your oven to 350f and line two baking sheets with parchment paper.
In a medium-sized bowl combine the flour, baking soda, baking powder, and salt and set aside.
In a large bowl, or the bowl of a stand mixer fitted with a paddle attachment, cream the butter and sugar on medium speed (about 2 minutes). Scrape down the sides of the bowl if needed.
Add both eggs, 1 at a time, and continue to beat on medium until incorporated.
Add the ricotta cheese, vanilla extract, and lemon zest and continue to beat until incorporated, scraping down the sides of the bowl if needed.
Begin to add the flour mixture to the ricotta and butter mixture a little at a time while beating on a low speed until the mixture just until everything is incorporated. Don't overmix. The dough will be sticky and thick.
Using a scooper or spoon, begin to drop 1 1/2 tablespoon-sized balls of the dough onto the parchment paper and bake for 12-14 minutes or until lightly golden on the edges.
Remove the cookies from the baking sheet and allow them to cool on a wire rack.
