Baked Oatmeal Gluten-Free with Mixed Berries: Step-by-Step Guide

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your Baked Oatmeal Gluten-Free with Mixed Berries bakes evenly.
Step 2: Prepare the Baking Dish
Grease your 9×9-inch baking dish with a bit of coconut oil or butter to prevent sticking.
Step 3: Combine Dry Ingredients
In a large mixing bowl, combine the rolled oats, half of the chopped walnuts, baking powder, and ground cinnamon. Stir until well mixed.
Step 4: Mix Wet Ingredients
In another bowl, whisk together the maple syrup, almond milk, beaten egg, melted coconut oil or butter, and vanilla extract until smooth.
Step 5: Combine Everything
Pour the wet mixture over the dry ingredients and stir until all the oats are well coated. Gently fold in the sliced bananas and mixed berries, being careful not to mash the berries.
Step 6: Bake
Spread the oatmeal mixture evenly in the prepared baking dish. Sprinkle the remaining chopped walnuts on top for added crunch. Bake for 30-35 minutes or until the top is golden brown and the center is set.
Step 7: Cool and Serve
Once baked, remove the dish from the oven and let it cool for a few minutes. Cut into squares and serve warm. This dish is delightful on its own or topped with additional maple syrup or a dollop of yogurt.
Swap Guide

- Oats: You can substitute with steel-cut oats, but adjust the cooking time as they will take longer to bake.
- Nuts: If you have nut allergies, feel free to use seeds like sunflower or pumpkin seeds instead.
- Milk: Any plant-based milk, such as oat milk or soy milk, can be used in place of almond milk.
- Sweetener: Honey or agave syrup can replace maple syrup for a different flavor profile.
What Not to Do
- Do not skip the baking powder; it helps the oatmeal rise and gives it a fluffy texture.
- Avoid overmixing the batter once you’ve added the wet ingredients; this can lead to a dense final product.
- Don’t forget to grease your baking dish, or you’ll end up with a stuck mess.
- Be cautious with the baking time; underbaking may result in a soggy center, while overbaking will lead to dry oatmeal.

For longer storage, consider freezing portions in individual containers. To reheat, simply microwave a serving for about 30-60 seconds, or until warmed through.
