Blueberry Oatmeal Ingredients

- Oats: A mix of old-fashioned rolled oats and quick oats gives the best texture.
- Milk: Unsweetened almond milk or any non-dairy milk keeps it plant-based; use regular milk if preferred.
- Cinnamon: A small amount adds warm flavor without overpowering the berries.
- Maple syrup: Natural sweetener; honey works as an alternative.
- Bananas: Ripe bananas add natural sweetness and moisture.
- Blueberries: Frozen berries are convenient and work well; fresh is fine when in season.
- Vanilla extract: Enhances the overall flavor.
- Baking powder: Gives a light lift—make sure it’s fresh.
- Salt: A pinch brightens the flavors.
- Lemon zest: A little zest complements the berries.
- Toppings: Fresh fruit or whipped topping are optional finishes.
How To Make Blueberry Oatmeal Bake
- Preheat and prepare: Preheat the oven to 375°F and spray a baking dish with nonstick spray.

- Make the wet mixture: Mash the bananas, then stir in the almond milk, maple syrup, and vanilla.
- Mix the dry ingredients: In a separate bowl, combine rolled oats, quick oats, cinnamon, lemon zest, salt, and baking powder.

- Combine and fold: Stir the wet and dry ingredients together until combined, then gently fold in the blueberries.

- Bake: Transfer the mixture to the prepared dish, top with extra frozen blueberries if desired, and bake 30–35 minutes until set and golden at the edges.
- Rest and serve: Let the bake cool for a few minutes before serving warm, or allow it to cool completely. Top with fresh fruit or whipped topping if you like.
Tips To Make Baked Oatmeal with Blueberries
- Use a balance of rolled and quick oats for the nicest texture; avoid instant oats.
- Do not thaw frozen blueberries before folding them in to prevent the batter from turning purple or watery.
- Fresh berries can be used when available for a brighter fruit flavor.
- Add extra berries or chopped nuts on top before baking for added texture.
- This bake stores well in the fridge for several days and freezes nicely for up to three months.
- Allow the oatmeal to rest 5–10 minutes before serving so it firms up and slices cleanly.
