Step 1: Preheat and Prepare: Heat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
Step 2: Mix Wet Ingredients: Cream butter and sugar until light and fluffy. Add eggs, lemon juice, and zest, mixing until smooth.
Step 3: Combine Dry Ingredients: In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
Step 4: Form the Dough: Gradually add dry ingredients to the wet mixture. Stir until a soft dough forms.
Step 5: Shape and Bake: Scoop tablespoon-sized dough, roll into balls, and place on the baking sheet. Flatten slightly. Bake for 10–12 minutes or until edges are set.
Step 6: Cool: Let cookies cool on the sheet for 5 minutes, then transfer to a wire rack.
Step 7: Prepare the Glaze: Whisk powdered sugar and lemon juice until smooth. Add zest if desired.
Step 8: Glaze Cookies: Drizzle or spread glaze over cooled cookies. Let set before serving.
