Preheat oven to 375°F (190°C) and line baking sheets with parchment paper.
In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
In a large bowl, beat butter and sugar until light and fluffy.
Mix in eggs one at a time, then stir in lemon juice, lemon zest, and vanilla extract.
Gradually add dry ingredients to the wet mixture, stirring until just combined.
Drop spoonfuls of dough onto baking sheets, leaving 2 inches apart.
Bake for 10–12 minutes or until edges are golden.
Cool cookies on the baking sheet for 5 minutes, then transfer to a wire rack. Dust with powdered sugar.
