These lavender shortbread cookies bring a gentle floral aroma to classic buttery shortbread, while the honey glaze adds just an extra touch of sweetness.
Cream the butter - Add softened butter, vanilla, honey, sugar and salt to a stand mixer bowl fitted with the paddle attachment. Beat on medium speed until the mixture is thoroughly incorporated and creamy.
8 oz unsalted butter, ⅔ cup granulated sugar, 2 tablespoon honey, 1 teaspoon pure vanilla extract, ¼ teaspoon kosher salt
Grind dried lavender - Add dried lavender flower to a mortar and grind against the bottom and side by twisting the pestle firmly on top of the dried flowers until you get a fine powder. Don’t have a pestle and mortar? Try crushing the flowers in a ziploc bag with a rolling pin.
2 teaspoon dried lavender flower
Incorporate dry ingredients - Sift the flour, cornstarch and lavender powder directly into the creamed butter using a fine mesh sieve, stir to combine. Increase the mixer speed and beat until no trace of flour remains and the dough is formed.
2 ¼ cup all-purpose flour, 2 tablespoon cornstarch
Form the logs - Place a long piece of plastic wrap flat on the countertop. Divide cookie dough into 2 equal portions. Roll each portion on top of the plastic wrap into a log about 6” in length. Wrap it up with the plastic and refrigerate for at least 1 hour. You don’t need additional flour for rolling but you can use some flour if necessary. I usually refrigerate shortbread dough overnight to prep ahead.
Slice the cookies - Use a sharp knife to slice each cookie dough log into 12 cookies about ½” thick. Rewrap in the same plastic and place them into the freezer while the oven preheats. Or you can freeze for longer storage at this point.
Preheat the oven - Set the oven rack in the middle of the oven and preheat to 350°F.
Bake - Place 12 cookies on a large lined baking sheet, about 2 inches apart. Bake 1 batch at a time for 20 minutes, until the outer edges of the cookies are golden.
Cool - Remove the baking sheet from the oven, but allow the cookies to sit on the baking sheet to finish baking from the residual heat for 5-10 minutes before removing them to a wire rack to cool completely.
Make the glaze - When the cookies are completely cool and you’re ready to decorate, make the glaze by adding honey, milk, powdered sugar and salt to a small mixing bowl and whisk until smooth.
2 tablespoon honey, 2 tablespoon milk, 1 cup powdered sugar, A few pinches of kosher salt
Glaze the cookies - Dip cooled cookies, top side down, into honey glaze and place them on a baking sheet. If there are bubbles or imperfections, you can use a toothpick to pop the bubbles or move the glaze around to fix the imperfections.
Decorate - Add a few dried lavender flowers on top of the glazed cookies before the glaze dry to decorate them if you wish. I recommend using a tweezer for exact placement. Then let the glaze dry completely on the baking sheet before storing or stacking the cookies.
