Make the flax egg by combining water and ground flaxseed in a small bowl, then set aside for 10-15 minutes, until the mixture has a gel-like consistency.
Preheat the oven to 350°F and prepare your baking dish by lightly spraying it with cooking spray.
Add the coconut oil to a large microwave-safe mixing bowl, then melt it in the microwave. Add in milk, maple syrup, flax eggs, and vanilla and whisk together.
Add the oats, baking powder, cinnamon, and nutmeg and mix until combined. Stir in any mix-ins you’d like, then pour the mixture into the prepared baking dish.
Bake for 23-30 minutes, or until the baked oats are golden brown and baked in the middle. The centre should no longer be jiggly. Sprinkle with more toppings if desired, let cool for 5 minutes, and enjoy!
