01 - In a large mixing bowl, blend unsalted butter and granulated sugar with an electric mixer until pale and fluffy, approximately 2 minutes.
02 - Add honey and finely chopped lavender buds to the mixture, beating until well combined.
03 - Sift all-purpose flour, cornstarch, and salt together, then gradually add to the wet mixture, blending on low speed until a soft dough forms.
04 - Turn dough onto a lightly floured surface and gently knead until just combined. Form into a disk and wrap in plastic wrap.
05 - Refrigerate wrapped dough for at least 1 hour to facilitate easier rolling and cutting.
06 - Set oven to 350°F (175°C). Line a baking sheet with parchment paper.
07 - Roll the chilled dough to 1/4-inch thickness and cut into desired shapes using cookie cutters.
08 - Place cookies on prepared sheet and bake for 12 to 15 minutes, or until edges are light golden.
09 - Allow cookies to cool on the sheet for 5 minutes before transferring to a wire rack to cool fully.
