Step 1: Prep and Preheat

1. Preheat your oven to 350°F (175°C).

2. Line your baking sheets with parchment paper or silicone mats and set aside.

Step 2: Make the Cookie Dough

1. In a large bowl, cream the butter and sugar together until light and fluffy (about 2–3 minutes).

2. Beat in the eggs one at a time, mixing well after each addition.

3. Add the lemon zest, lemon juice, and vanilla extract. Mix until well combined.

4. In a separate bowl, whisk together the flour, baking powder, and salt.

5. Gradually add the dry ingredients to the wet mixture, mixing until a soft dough forms. It will be slightly sticky.

Step 3: Shape and Bake

1. Use a tablespoon or small cookie scoop to portion the dough. Roll into smooth balls with lightly floured or damp hands.

2. Place the cookie balls on the prepared baking sheets about 2 inches apart.

3. Bake for 10–12 minutes, or until the bottoms are lightly golden and the tops are set (but not browned).

4. Let the cookies cool for 5 minutes on the sheet, then transfer to a wire rack to cool completely.

Step 4: Prepare the Glaze

1. In a small bowl, whisk together powdered sugar and lemon juice until smooth.

2. Add more lemon juice for a thinner glaze or more powdered sugar for a thicker consistency.

3. Stir in lemon zest if desired.

Step 5: Glaze and Decorate

1. Once the cookies are cool, dip the tops into the glaze or spoon it over each cookie.

2. While the glaze is still wet, decorate with sprinkles if desired.

3. Place cookies on a rack and let the glaze set for 30–60 minutes before serving or storing.
