This slice sits somewhere between a cake and baked oatmeal in texture, lovely and sturdy and filling too, which is exactly what I was looking for in a good plane snack. The little pops of blueberry are awesome and I reckon next time I'm gonna try it out with raspberries to counteract the sweetness of the slice, maybe swapping in brown rice syrup for the honey too. I use quinoa flakes for a 100% gluten-free slice, however if you tolerate oats by all means use them. I'm thinking buckwheat flour or quinoa flour would also work as great substitutes for the brown rice flour if that's what you've got.
