Preheat oven to 350 degrees. Line baking sheets with silicone mats or parchment paper and set aside. In a large mixing bowl, cream the butter and sugar together until light and fluffy. Add the vanilla, egg, lemon juice and lemon zest. Beat until well combined. Set aside.
In a separate bowl, whisk together the flour, salt, baking powder and baking soda. Add the dry ingredients to the wet ingredients and stir just until they are combined. Place the powdered sugar in a small bowl and set aside.
Scoop about a tablespoon of the cookie dough and roll into a ball. Roll in the powdered sugar and then place on the cookie sheet. Repeat with the rest of the dough. Bake for about 10 minutes, or just until the bottoms of the cookies begin to brown and the cookies are no longer shiny. Remove from the oven and let rest for a minute or two before transferring to a wire rack. Store in an airtight container when completely cooled. Enjoy!
