You're back to Essene Bread again.

But you need a dehydrator with air/fan control besides heat control to get the best product, some dehydrators just don't make a decent Essene Bread.

Your other alternative for "Pancake Flavour" is to use a Solar Oven, but then its not raw. Unless you are lucky enough to live in an arid dessert and simply place the dough on a rock {as in traditional unleavened bread}.

And from above I am not sure how such a little amount of Baking Podwer would do any good unless you cooked them? However yeast/sourdough,or Rejuvelac and/or patience {just depends on your view of yeast though}.
