In my quest to bake a gluten-free ANZAC biscuit, I have replaced oats (not considered gf in Australia) with rolled quinoa flakes and the flour with a blended gf flour and sorghum flour. I also added in some gf Freedom Foods "Rice Puff" cereal to make them a little lighter (this cereal is like Rice Bubbles). I've made a few batches now making slight changes each time......I'm happy with this version. My family said it's not bad for a gluten-free version....but not quite an Anzac biscuit. Made using Australian cup and spoon measures. I managed to buy some sorghum flour labelled as Jowar flour at a local Indian grocer.
