This video introduces a recipe for crunchy rice flour matcha cookies made without eggs or butter. The dough is made by mixing rice flour, cornstarch, powdered sugar, matcha powder, and rice oil. It's then shaped into a log and cut into approximately 1cm wide slices. After rolling them into balls and baking in the oven, they are cooled and then coated with a mixture of non-melting powdered sugar and matcha powder. Adding cornstarch prevents the cookies from becoming too hard, resulting in a crisp, gluten-free treat. Tips for making the dough and finishing touches are also carefully explained.
