Preheat oven to 350oF. In a large bowl mix buckwheat flour, cinnamon, egg whites, and a pinch of salt. Mix it until a smooth dough. Roll it out in a little buckwheat flour until 1⁄3” thick. Use a cutter and turn them into cookies. Brush a thin layer of coconut oil on each side and place them on a parchment covered baking rack. Bake until dry and crisp. Mix together all the spices in a small bowl and sprinkle a little on each cracker while they are warm.
