Mix Dry Ingredients: In a bowl, whisk together the all-purpose flour, baking soda, and salt. This blend lays the foundation for your airy cookies. Set aside as you move on to the next steps.

Prepare Wet Ingredients: In a large mixing bowl, whisk melted butter and granulated sugar until smooth and creamy. Add the egg, egg yolk, vanilla extract, lemon juice, and zest, mixing until well combined for a luscious, flavorful batter.

Combine Mixtures: Gradually stir in the dry ingredients until a dough forms. If needed, don’t hesitate to use your hands to combine everything smoothly. The dough should be slightly sticky but manageable.

Chill Dough: Cover the dough tightly with plastic wrap and refrigerate for 2 to 4 hours. Chilling is key here to allow the flavors to meld and to help the cookies keep their shape while baking.

Preheat & Prepare Baking Sheets: Preheat your oven to 325°F (163°C). Line two baking sheets with parchment paper to ensure easy cleanup and prevent sticking.

Shape Cookies: Roll the chilled dough into 1-inch balls. Next, coat each ball generously with powdered sugar to give them that characteristic snow-dusted look—this is what makes them truly irresistible!

Bake: Arrange the coated balls on the prepared baking sheets, leaving about 2 inches between them. Bake for 10-12 minutes, until the edges are set and the centers are still slightly jiggly for that perfect chewy texture.

Cool: Once baked, allow the cookies to cool on the sheets for a few minutes before transferring them to a wire rack to cool completely. Patience pays off as they finish firming up!
