How to Make It
Preheat an oven to 375 degrees.
In a small bowl, mix ground flax seed with three tablespoons warm water. Set aside.
In separate bowls, mix all dry ingredients together (cake flour through sugar) and then mix wet ingredients (coconut oil through vanilla extract). Combine the two bowls and flax mixture. Stir together, taking care to not over mix the batter.
Carefully spoon (or use a pastry bag to pipe) batter into an oiled doughnut pan.
Bake 9-11 minutes or until a toothpick comes out clean.
Let sit for 5 minutes, then place doughnuts on a cooling rack. If using, in a small bowl mix glaze ingredients together. Once the doughnuts are cool, they can be finished by dipping in glaze or sprinkling powdered sugar atop.
