I can't vouch for how well these cookies will turn out with any other gluten free multipurpose flour mix besides
King Arthur Flour Company's*. KAF gluten free flours are truly superior, without any of the bitter flavors or gritty texture characteristic of many GF blends. In addition, I've noticed that KAF flour absorbs much more moisture than others, so using another flour blend may require that you experiment with the amount of milk or butter sticks.
