1️⃣ Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
2️⃣ Cream the butter and sugar: In a large bowl, beat the softened butter and powdered sugar until light and fluffy.
3️⃣ Add flavorings: Mix in the lemon zest, lemon juice, and vanilla extract until well combined.
4️⃣ Combine dry ingredients: In a separate bowl, whisk together the flour and salt.
5️⃣ Form the dough: Gradually add the flour mixture to the butter mixture. Mix until a soft dough forms.
6️⃣ Shape the cookies: Scoop 1-tablespoon portions of dough and roll into balls. Place them on the prepared baking sheet about 2 inches apart.
7️⃣ Flatten gently with the bottom of a glass or your palm.
8️⃣ Bake for 12–14 minutes, or until the edges are just turning golden. Let cool on the sheet for 5 minutes, then transfer to a wire rack.
9️⃣ Prepare the glaze: Whisk together powdered sugar, lemon zest, and lemon juice until smooth.
🔟 Glaze and set: Once cookies are completely cool, spoon or brush the glaze over the tops. Allow to set before serving.
