01 - Beat softened butter and powdered sugar in a large mixing bowl until pale and fluffy, approximately 3-4 minutes.
02 - Fold in lemon zest, chopped lavender, and salt until evenly distributed throughout the mixture.
03 - Gradually incorporate flour, mixing on low speed just until dough forms and no dry flour remains visible. Avoid overmixing.
04 - Divide dough into two equal portions. Roll each into a 2-inch diameter log, wrap securely in plastic, and refrigerate for 30 minutes until firm.
05 - Set oven to 350°F. Line two baking sheets with parchment paper and set aside.
06 - Cut chilled dough logs into 1/4-inch thick rounds. Place on prepared baking sheets with 1-inch spacing between cookies.
07 - Bake for 14-16 minutes until edges turn golden brown. Cool on sheets for 5 minutes before transferring to wire rack.
08 - Whisk powdered sugar, lemon juice, and zest until smooth and glossy. Adjust consistency with additional lemon juice if needed.
09 - Drizzle or spread glaze over completely cooled cookies. Garnish with lavender buds and allow glaze to set before serving.
