Instructions

1 Preheat your oven to 375°F (190°C) and lightly grease an 8x8 inch baking dish. In a large bowl, combine the gluten-free oat flakes, gluten-free baking powder, ground cinnamon, ground nutmeg, and salt. Whisk these dry ingredients together until well combined and fragrant.
2 In a separate medium bowl, whisk together the eggs until lightly beaten. Then, stir in the milk, maple syrup (or honey), melted butter (or coconut oil), and pure vanilla extract until everything is smoothly incorporated. This mixture should be liquid and aromatic.
3 Pour the wet ingredients into the bowl with the dry ingredients. Gently fold them together with a spatula until just combined, ensuring no dry streaks remain. Be careful not to overmix, as this can result in a tougher texture. The batter should be thick but pourable.
4 Pour the batter evenly into the prepared baking dish. Place the dish in the preheated oven and bake for approximately 30-35 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The oatmeal should be set and slightly puffed.
5 Once baked, carefully remove the dish from the oven and let it cool for about 5-10 minutes before serving. This allows the baked oatmeal to set further. Serve warm, perhaps with fresh berries or a drizzle of extra maple syrup.
