Preheat oven to 350 degrees F (175 degrees C) and line baking sheets with parchment paper.

In a medium bowl, whisk together the flour, baking soda, baking powder, and salt.

In a large bowl, cream together the softened butter and 1.5 cups of sugar until light and fluffy.

Beat in the egg, lemon zest, lemon juice, and vanilla extract until well combined.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Shape the dough into 1-inch balls and roll each ball in the remaining 0.25 cup of sugar.

Place the balls onto the prepared baking sheets about 2 inches apart.

Bake for 8 to 10 minutes or until the edges are lightly golden.

Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
