Pour the sugar and dried lavender buds into a food processor. Process for 10-15 seconds. Taste and adjust with more lavender if needed.
¾ cups (150 g) granulated sugar, 1 teaspoon dried lavender buds
Add in the lemon zest and process until the texture of the lavender sugar resembles wet sand.
2 lemons, zested
Using a stand mixer fitted with paddle attachment or electric hand mixer with beaters, beat the room temperature butter and lemon lavender sugar until well combined. This takes about 3-4 minutes on medium speed.
1 cup (226 g) unsalted butter, softened
Mix the flour and salt into the wet ingredients until just combined. Cover the dough and chill in the fridge for 30 minutes.
2¼ cups (270 g) all purpose flour, ¼ teaspoon salt
While the cookies chill, preheat the oven to 350 F (177 C). Line two large baking sheets with parchment paper.
Scoop about 1 tablespoon (15 ml) of cookie dough onto the prepared baking sheet. I like to use a small cookie scoop to get perfectly portioned cookies.
Bake the lavender sugar cookies for 12 - 14 minutes. The bottom of the cookies will be very lightly golden brown. Remove the cookies from the oven onto a cooling rack. After 3 minutes, transfer the cookies off the hot baking sheet and onto the cooling rack to cool to room temperature. Make the lemon glaze for the lavender cookies by mixing 2 - 3 tablespoons (30 ml) lemon juice with 1 - 1 ½ cups (120 - 180 g) of powdered sugar until well combined.
1 - 1½ cups (120 -180 g) powdered sugar, 2 -3 tablespoon lemon juice
Top each cookie with the lemon glaze. Sprinkle very finely chopped dried lavender on top if you like.
¼ teaspoon dried lavender buds
