These Matcha Shortbread Cookies are the easiest cookies to make that yield to tender, crisp, buttery shortbread cookies with the unique flavor of matcha.
In a medium bowl, mix the flour, matcha powder, and salt until well combined. Set aside.
Using a hand mixer or stand mixer fitted with a paddle attachment, cream together butter, confectioners sugar, and vanilla extract until incorporated.
Scrape the bowl down and sift in the dry ingredients. Mix with a spatula until the dough starts to come together. It will look crumbly at first, but the dough will come together as you continue mixing.
Wrap the dough with plastic wrap. Chill the dough for at least 30 minutes in the refrigerator or until it is firm enough to cut through.
Preheat oven to 350℉/180℃ and line two baking pans with parchment paper.
Take the dough out of the refrigerator and open the plastic wrap. Roll the dough into a 1/5-inch (5 mm) thick slab. Cut the dough with a 1.5-inch (4 cm) cookie cutter. Place the cut dough on baking sheets, spaced at least an inch apart. Re-roll the scraps and refrigerate for a few minutes until firm again. Repeat the process until all the dough is used.
Use a skewer to poke holes in the cookies (optional).
Chill in the refrigerator for another 30 minutes if the dough has warmed up.
Bake for 13-16 minutes or until the bottom edges of the cookies are golden brown in color.
Transfer to a wire sheet to cool completely.
Notes
Use cake flour for light, crisp, and tender cookies. Use all-purpose flour for softer and chewier cookies.
