In a large bowl, mix the ground flax with the water to make a "flax egg". Let sit for 5 minutes.
In a medium bowl, whisk together all the dry ingredients.
Add the remaining wet ingredients to the flax egg and mix well.
Add the dry ingredients to the wet ingrdients and mix until combined.
Let the batter sit for 15 minutes.
Preheat the oven to 375 degrees Farenheit and line a muffin tray with liners.
Divide the batter into the 12 muffins liners. They'll fill up almost to the top.
Bake in a preheated oven for 20 minutes, or until a knife comes out clean.
Let cool, then enjoy!
