Step 1

Preheat the oven to 350?. Line 2 baking sheets with parchment paper.

Step 2

To make the lavender sugar, place the sugar and 1 tablespoon of lavender flowers in a bowl. Mix together with a spoon and set aside.

Step 3

Place the butter, powdered sugar, flour and 1 tablespoon of the lavender sugar in the bowl of a food processor and pulse until the dough comes together to form a ball.

Step 4

Turn the dough out onto a floured worktop and roll to ¼-inch thickness. Cut into rounds using a 2-inch cookie cutter. Roll up the dough scraps and repeat until done. Place on the prepared baking sheets and place in the freezer for 15 minutes.

Step 5

Remove from the freezer and sprinkle generously with lavender sugar. Bake in the preheated oven for 12–15 minutes until golden brown.

Step 6

Remove and cool on a wire rack. When the cookies have cooled, divide them in two. Pipe the vanilla frosting on one cookie and top with the other. Sprinkle with a little more lavender sugar and serve.
