Preheat oven to 375 F.
Line two rimmed baking sheets with parchment paper and set aside.
In a medium bowl, whisk together the oat flour, hemp protein powder, cinnamon, salt and baking soda until all dry ingredients are evenly distributed. Set aside.
In another bowl, whisk the oils with the maple syrup, the flax meal, water, and vanilla, until well blended.
Pour the moist ingredient mixture into the dry one and whisk until well incorporated. Switch to a spatula and mix in coconut, nuts, chocolate chips, seeds, oats, and popped grain. Make sure all the add-ins are evenly distributed. If possible, let cookie dough rest for 20 minutes, it will set and become more of a dough than a batter, and will be easier to work with it.
With mini ice cream scoops or 2 spoons, scoop out dough balls (about 1-inch diameter) onto prepared baking sheets, leaving 1 inch in between each ball. Flatten each ball lightly with your palms and bake for about 9 to 11 minutes until cookies brown a bit and smell amazing. Cool on a rack and repeat until all the dough has been used.
