In a medium saucepan over low to medium heat, melt the butter slowly. Stir constantly to prevent it from burning. As the butter melts, it will begin to foam and release a nutty aroma. Once you see light brown solids forming at the bottom of the pan, immediately remove it from the heat. Transfer the brown butter to a heat-safe bowl and let it cool to room temperature. Brown butter can burn quickly, so keep an eye on it during this step.

In a large bowl or stand mixer, combine the white sugar, brown sugar, and cooled brown butter. Beat the mixture until it’s fully combined and has a texture resembling wet sand. Add the eggs, one at a time, mixing well after each addition until the mixture is smooth and glossy.

Sift the flour, matcha powder, baking powder, and salt into a separate bowl to remove clumps and evenly distribute the matcha. Gradually add the dry ingredients to the wet mixture, mixing until a thick dough forms. Be careful not to overmix, as this can make the cookies dense instead of soft and chewy.

Cover the dough tightly with cling wrap and refrigerate for at least 1 hour or overnight for best results. Chilling the dough is crucial—it firms up the butter, prevents the cookies from spreading too much, and enhances the flavors.

When ready to bake, preheat your oven to 350°F (180°C). Line a baking sheet with parchment paper.

Using a round spoon or ice cream scoop, portion out 2-inch dough balls. Roll each ball first in white sugar to create a caramelized base layer, then coat generously in icing sugar for the signature crinkle effect.

Arrange the coated dough balls on the prepared baking sheet, leaving about 2 inches of space between each cookie to allow for spreading. Bake for 10-12 minutes, or until the cookies puff up and develop crinkles on the surface. The centers should still look slightly soft—they’ll firm up as they cool.

Transfer the cookies to a wire rack and let them rest for at least 5 minutes before serving. Enjoy warm for a gooey texture, or allow them to cool completely for a chewier bite. Either way, these Brown Butter Matcha Crinkle Cookies are a treat to savor!
