Preheat oven to 350 F.
In a blender or using a food processor, add the cashews, dates, vanilla, coconut oil, cinnamon, salt, egg whites and if using dried egg whites add them with 2 tablespoons water and honey if using it.
Blend and pulse until smooth.
Pour onto a parchment paper or a lined or greased cookie sheet and spread out evenly into a large square that is about 1/2 inch thick.
Bake for 13-15 minutes or until bars feel slightly firm, they will firm up more once out of the oven.
Slice into desired bars, I usually do 12 large squares,
You do not need to refrigerate these but it will improve the shelf life. I also freeze them in individual bags.
