Step 1: Preheat & Prepare the Baking Sheet

• Preheat your oven to 350°F (175°C).
• Line a baking sheet with parchment paper or lightly grease it.

Step 2: Mix the Dry Ingredients

• In a medium bowl, whisk together:
  • Flour
  • Baking powder
  • Baking soda
  • Salt

Set aside.

Step 3: Cream the Butter & Sugar

• In a large mixing bowl, beat the butter and sugar together until light and fluffy (about 2 minutes).
• Add the egg, lemon zest, lemon juice, and vanilla extract, and mix until combined.

Step 4: Combine & Chill the Dough

• Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
• Cover the dough and chill for at least 30 minutes for best results (this helps the cookies hold their shape).

Step 5: Shape & Bake

• Scoop 1 ½ tablespoon-sized dough balls and place them 2 inches apart on the baking sheet.
• Bake for 10-12 minutes, or until the edges are set and slightly golden.
• Let cool on the baking sheet for 5 minutes, then transfer to a wire rack.

Step 6: Make the Lemon Glaze

• In a small bowl, whisk together powdered sugar, lemon juice, and lemon zest until smooth.
• Drizzle the glaze over the cooled cookies.

Step 7: Serve & Enjoy!

• Allow the glaze to set for 15 minutes, then enjoy these buttery, tangy, and sweet lemon cookies!
