Get a large, shallow dish big enough for holding a large slice of bread and add the oat milk
Add ground flaxseed, baking powder, cornstarch, and cinnamon
Whisk the mixture until you have no lumps, then dip one slice of bread in mixture, turn it over and dip the other side
Heat a nonstick frying pan for several minutes until hot, (no oil needed) then put in 2 or 3 slices of coated bread .Cook for 3 minutes. Once browned, turn over and cook for 3 minutes. You may need adjust the cook time, depending on the temperature of your pan. If the French toast is not cooked enough it may stick to the bottom of the pan.
You may add unsweetened applesauce, sprinkle on more cinnamon, fresh fruit, or a tiny amount of maple syrup on the French toast. I like to put a little syrup on the plate and dip my toast into the syrup. Enjoy!
