In order to make French toast without eggs or dairy, you need to create a custard-like finish that will bake and hold shape in the oven. In place of eggs, you can use corn starch, or a flax egg (1 tbsp ground flax + 2.5 tbsp water) to thicken the custard. The milk replacer in this recipe is coconut milk. You can use different dairy-free milk such as almond milk, cashew milk, or soy milk.
