Preheat Oven: Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
Cream Butter and Sugar: In a large bowl, cream together softened butter and granulated sugar until light and fluffy.
Add Wet Ingredients: Beat in eggs, vanilla extract, lemon juice, and lemon zest until well combined.
Combine Dry Ingredients: In a separate bowl, whisk together flour, baking powder, and salt. Gradually add dry ingredients to wet ingredients, mixing until just combined.
Shape Cookies: Scoop about 1–2 tablespoons of dough and roll into balls. Roll each ball in powdered sugar until coated.
Bake: Place cookies on prepared baking sheet about 2 inches apart. Bake for 10–12 minutes, until edges are set but centers are still soft.
Cool: Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
