Kerrygold Lemon-Thyme Shortbread Cookies

Instructions

• Preheat the oven to 350°F (180°C). Line 2 baking sheets with parchment paper.
• In a large bowl, cream together the Kerrygold™ Pure Irish Unsalted Butter and granulated sugar with an electric hand mixer on medium speed until light and fluffy, about 5 minutes.
• Scrape down the sides of the bowl, then add the lemon juice, egg yolk, and lemon zest, and mix until well-combined, about 2 minutes.
• Add the flour, cornstarch, cardamom, salt, and chopped thyme. Mix with a rubber spatula to incorporate, then continue mixing with the hand mixer on low speed until the dough comes together, about 3 minutes. Wrap the dough in plastic wrap and refrigerate for 20 minutes.
• Roll out the dough between 2 sheets of parchment paper to a ¼-inch-thick rectangle. Trim the edges to make a perfect rectangle, roughly 10½ x 6 inches. Using a knife, cut out 28 1½-inch squares.
• Place the cookies on the prepared baking sheets, spacing about 2 inches apart. Press a small sprig of thyme onto the top of each cookie, then sprinkle with coarse sugar. Freeze the cookies on the pans for 10 minutes (this will help them hold their shape while baking).
• Bake the cookies for 12–14 minutes, or until golden around the edges. Remove from the oven and let cool completely, about 30 minutes.
• Enjoy!
