In a small bowl mix flax meal, oat milk, vanilla and cinnamon. Set it aside for 10 to 15 minutes for it to thicken.
Submerge the bread into the flax egg mixture to coat it evenly on both sides.
Heat a griddle or large nonstick pan with the oil or butter over medium heat. Add the bread and cook on each side for about 3-4 minutes.
I use oat milk to make this French toast sticks recipe but you can also use almond milk, cashew milk, or different nut milk if you do not have to be nut-free.
Avoid soaking the bread in the flax mixture for too long or the French toast sticks will turn mushy and fall apart.
I like serving this with a bit of berry yogurt sauce so my little ones can practice dipping their foods. Cook some berries with a little water and lemon zest until soft and glossy, let it cool, and stir in a couple of tablespoons of yogurt to make a sauce. Be sure to use a non-dairy yogurt if you want to keep this recipe vegan-friendly.
