To make the cookies: Preheat the oven to 350ºF. Line 2 baking sheets with parchment paper or nonstick silicone liners.
Combine the flour, baking soda and salt in a small bowl.
Combine the butter and granulated sugar in the bowl of a stand mixer fitted with the paddle attachment and beat on high speed until light and fluffy. Add the ricotta, eggs and vanilla extract, and beat until thoroughly incorporated. Reduce the mixer speed to low and add the flour mixture, beating until just combined. Refrigerate dough if not baking right away.
