You take the milk and mix it with vinegar. Set it aside (you'll get vegan buttermilk).
Combine rice and oat flour with baking soda, baking powder, salt, vanilla powder, and xanthan.
Then take your mixer and whisk aquafaba till you can notice beautiful firm stiff peaks. Add sugar and mix for another minute or two on high speed.
Take buttermilk and mix it with dry ingredients. You'll get thick batter - it's okay.
Little by little, few spoons at once by using the spatula incorporate aquafaba mixture into the batter. Let it rest for about 10 minutes.
Heat a non-stick pan over medium-low, melt some coconut oil, and grease the pan. Pour batter onto the pan and let it spread out into a round pancake. Cook it until bubbles appear, then flip and cook until golden.
NOW, ENJOY!
