I tried these with millet instead of almond flour.
I had to bake them at 350 for about 45 minutes before they solidified at all. And I used xylitol and they are VERY sweet, though I am sensitive to sweet and salty things. Next time I would use more flour and less xylitol. These make a lovely treat to break up a dull diet!
PS – this recipe made 14 large muffins for me.
