Add the Butter and Granulated Sugar to a large mixing bowl and cream them together for about 2 to 3 minutes, or until they are light and fluffy. 1/2 cup Unsalted Butter, 3/4 cup Granulated Sugar
Add in the Ricotta Cheese, Egg, Lemon Juice, Lemon Zest, and Vanilla Extract, and mix until just combined. The mixture may look a little curdled and chunky from the lemon juice, but its okay. 3/4 cup Whole Milk Ricotta Cheese, 1 large Egg, 1 TBS Fresh Lemon Juice, 2 tsp Fresh Lemon Zest, 1 tsp Vanilla Extract
Add in the dry ingredients, flour, baking powder, and salt and mix until just combined. Don't keep mixing or you will end up with dense cookies. 2 1/4 cups All Purpose Flour, 1 tsp Baking Powder , 1/2 tsp Salt
Cover the cookie dough and chill it in the fridge for at least 2 hours, up to overnight.
Preheat the oven to 350 degrees Fahrenheit. Line a cookie sheet with parchment paper.
Scoop the cookie dough into 1.5 Tablespoon portions (I measured mine out to be about 25g of dough) and roll into a smooth ball. Place the cookie dough balls onto the cookie sheet at least 2 inches apart.
Bake the cookies for 11 to 13 minutes, or until the tops of the cookies are set and the bottoms are lightly golden brown.
Let the cookies cool on the cookie sheet for 5 minutes, then transfer to a wire cooling rack to cool completely.
