Ingredients
Dry Ingredients
- 3 cups rolled oats (certified gluten-free if needed)
- 1 1/2 teaspoons baking powder
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 3-4 servings vanilla or plain protein powder (optional)
Wet Ingredients
- 2 1/4 cups dairy-free milk
- 2 large eggs
- 1/4 cup maple syrup
- 2 teaspoons vanilla extract
Fruit
- 1 1/2 cups fresh or frozen blueberries
Instructions
- Preheat oven and prepare pan. Preheat the oven to 350°F and line a 9×9-inch square baking dish with parchment paper to prevent sticking and ensure easy removal.
- Mix wet ingredients. In a large mixing bowl, whisk together the dairy-free milk, eggs, maple syrup, and vanilla extract until smooth and combined, creating the base for the oatmeal mixture.
- Add dry ingredients. Gradually stir in the rolled oats, baking powder, ground cinnamon, salt, and optional protein powder using a rubber spatula or wooden spoon until thoroughly combined.
- Incorporate blueberries. Gently fold in the blueberries, reserving about 1/2 cup to sprinkle on top for added texture and visual appeal before baking.
- Transfer to baking dish. Pour the oatmeal mixture into the prepared pan, smoothing the surface, and then evenly scatter the reserved blueberries on top.
- Bake the oatmeal. Place the baking dish in the preheated oven and bake for 45-50 minutes, checking at 30 minutes to cover the edges with foil if they appear too brown, until the center is set and the top is golden.
- Cool and serve. Allow the baked oatmeal to cool for 10-15 minutes. Cut into squares and serve warm or at room temperature, optionally topped with nut butter, Greek yogurt, chopped nuts, or additional fresh fruit.
Notes
- Use certified gluten-free oats if you need to keep the recipe gluten-free.
- Maple syrup adds natural sweetness, but you can adjust sweetness to taste or substitute with honey if preferred.
- Protein powder is optional but adds an extra nutritional boost; choose vanilla or plain flavor.
- Frozen blueberries can be used without thawing for convenience.
- Covering the edges with foil partway through baking prevents over-browning.
- For a creamier texture, let the baked oatmeal set longer before cutting.
