Preparation Steps

• In a medium bowl, combine the flour and salt. Set aside.
• In a large mixing bowl, beat the butter and confectioners' sugar together until light and fluffy, about 3-4 minutes.
• Add the lemon zest, thyme, and vanilla extract to the butter mixture, mixing until fully incorporated.
• Slowly add the flour mixture to the wet ingredients, stirring until a soft dough forms.
• Roll the dough into a log shape, wrap in plastic wrap, and refrigerate for at least 1 hour.
• Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
• Slice the dough into 1/4-inch thick rounds and place on prepared baking sheets, 2 inches apart.
• Bake for 13-15 minutes, or until the edges are golden brown.
• Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
