Chai cookies are soft, thick and chewy sugar cookies made with nutty brown butter and warm chai spice. They're rolled in a chai spiced sugar coating can be topped with a chai glaze.
Make the brown butter. Cool for the butter about 15 minutes at room temperature. Transfer the butter to the fridge to cool for another 15 - 20 minutes.
In a large mixing bowl, whisk in the cooled browned butter with the light brown and granulated sugars until well combined. Whisk in the egg, egg yolks and vanilla extract until smooth and well combined. Stir the dry ingredients into the wet until just combined.
Using a medium cookie scoop (2 tablespoons, 30 ml), scoop the chai sugar cookie dough, roll the dough ball into the spiced sugar and place the cookie dough balls onto the lined baking sheet about 3 inches (8 cm) apart.
