In a large bowl, beat the butter and sugar until light and fluffy, about 3 minutes. Add the eggs, one at a time, and beat until combined. Add the lemon juice, lemon zest and vanilla extract, and beat until combined.
Gradually add the dry ingredients to the wet ingredients, and beat until combined.
Drop by tablespoonfuls onto the prepared baking sheets. Bake for 10-12 minutes, or until the edges are lightly golden.
Let cool on baking sheets for 5 minutes before transferring to a wire rack to cool completely.
Dust with powdered sugar before serving. Enjoy!
