*I found the flours to be quite interchangeable. When I didn't have any rice flour on hand, I used sorghum flour for the rice flours and used either
millet or
quinoa flour in place of the sorghum flour. If using quinoa flour at all, I recommend increasing the sweetener to 1½ tablespoons as it does add notable bitterness if the sweetener is not increased.
**The mixture is quite sticky but thick enough that you might be able to bake it free-form (I haven't tried this yet) without it spreading too much. Plop four mounds onto a parchment or silicone mat-lined baking sheet and shape them with damp hands to rounds that are just over 4 inches in diameter.
