Preparation

  2. Whisk together the 2 cups flour, 1/2 teaspoon baking powder, and 1/4 teaspoon salt in a bowl until evenly combined.

  1. Beat 1/2 cup softened butter with 1 cup granulated sugar until light, add 1 large egg, 1 teaspoon vanilla, and the lemon zest; mix until smooth.
  2. Fold dry ingredients into the wet until just combined, scoop tablespoons of dough onto sheets, flatten slightly, and bake 8–10 minutes until edges are set; cool completely.
Buttercream Assembly
  1. Beat 1/2 cup softened butter with 2 cups powdered sugar, 1 tablespoon ground lavender, 2 tablespoons heavy cream, and 1 teaspoon vanilla; add purple food coloring if desired.
  2. Spread on a cookie, sandwich gently with another, and garnish with a thin lemon slice or lavender sprig for an elegant finish.

Notes

Use finely ground culinary lavender to avoid gritty texture. Chill dough for 15–20 minutes if too soft. Store in an airtight container for up to 3 days at room temperature or 1 week in the refrigerator.
