Why You’ll Love It
- Flavor & Texture: The combination of cinnamon-kissed oats with juicy blueberries creates a breakfast that’s both cozy and bright. A lightly crisp top gives way to a soft, comforting interior.
- Ease & Prep: Mix, bake, and serve — no special equipment required. It’s an ideal centerpiece for slow weekend mornings or a time-saving weekday dish you can reheat.
- Health Benefits: Rolled oats provide soluble fiber (beta-glucan) linked to heart health and sustained energy; blueberries add antioxidants and vitamins. This recipe uses maple syrup as a natural sweetener and plant-based milk to keep it lighter than many custard-style breakfasts.

Step-by-Step Instructions
Ingredients
- 2 cups rolled oats
- 2 cups almond milk (or any plant-based milk)
- 1 cup fresh or frozen blueberries
- 1/4 cup maple syrup or agave syrup
- 1 teaspoon baking powder
- 1 teaspoon cinnamon
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
Optional ingredients and substitutions
- 1 mashed banana (adds natural sweetness and moisture)
- 1/4–1/2 cup chopped nuts (walnuts, pecans) for crunch
- 1/4 cup Greek yogurt stirred into individual servings for extra protein (will change the “healthy” profile slightly)
- Use gluten-free certified oats to make the dish gluten-free
- Swap almond milk for cow’s milk or soy milk for higher protein content
Method
- Preheat the oven to 350°F (175°C).
- In a large mixing bowl, combine rolled oats, baking powder, cinnamon, and salt.
- In another bowl, whisk together almond milk, maple syrup, and vanilla extract.
- Pour the wet ingredients into the dry ingredients and stir until well combined.
- Gently fold in the blueberries.
- Pour the mixture into a greased baking dish (8×8-inch or similar).
- Bake for about 30–35 minutes or until the top is golden brown and the center is set (a toothpick inserted should come out mostly clean).
- Let it cool slightly before serving. Enjoy your healthy breakfast!
Practical tips
- Avoid overmixing once the wet and dry ingredients meet; overworking can make texture gummy.
- If using frozen blueberries, do not thaw — fold them in frozen to minimize color bleeding.
- Check doneness around 28–30 minutes if your oven runs hot; every oven is different.
- For a creamier interior, slightly underbake by 2–3 minutes; for a firmer texture, bake a few minutes longer.
- For other baked grain inspiration, check a few variations of baked breakfast classics like this baked breakfast roundup.
Best Pairings
- Serve warm with a spoonful of plain yogurt or a dollop of ricotta for creaminess.
- A light spread of nut butter (almond or peanut) on top adds richness and protein.
- Fresh fruit on the side (sliced banana, extra blueberries, or warm stewed apples).
- Drink pairings: bright coffee, a milky latte, or a soothing cup of chamomile tea.
- Portable option: cool, slice into squares, wrap individually for a healthy snack or breakfast-on-the-go.
Keeping it Fresh
- Room temperature: If kept covered, consume within 1 day (best practice is to refrigerate).
- Refrigeration: Store in an airtight container for up to 4–5 days. Reheat in the microwave for 45–90 seconds or warm a portion in a 350°F oven for 8–10 minutes.
- Freezer: Freeze in individual portions (wrap in parchment and foil or use freezer-safe containers) for up to 2–3 months. Thaw overnight in the fridge and reheat.
Chef’s Advice
- Use old-fashioned rolled oats for the best texture; quick oats can become mushy and steel-cut oats won’t set correctly without extra liquid and longer cooking.
- Let the baked oatmeal rest for 10–15 minutes after removing from the oven — it continues to set and is easier to slice.
- Balance sweetness to taste: start with 1/4 cup maple syrup; you can reduce to 2–3 tablespoons if you prefer less sugar, especially if adding a mashed banana.
- For golden top and deeper flavor, brush the top lightly with a teaspoon of melted coconut oil or a sprinkle of turbinado sugar before baking.
- Adjust cinnamon level to taste; add a pinch of nutmeg for cozy autumnal notes.
Fun Flavor Ideas
- Lemon-Blueberry Brightness: Add 1 teaspoon lemon zest and swap half the cinnamon for a teaspoon of vanilla bean paste. Finish with a drizzle of lemon glaze (optional).
- Chocolate-Almond: Stir in 2 tablespoons cocoa powder to the dry mix, fold in 1/4 cup dark chocolate chips, and top with sliced almonds.
- Apple-Pecan Spice: Replace blueberries with 1 cup peeled, chopped apples, add 1/4 teaspoon ground nutmeg, and fold in 1/3 cup chopped pecans.
- Protein Boost: Stir 1/2 cup Greek yogurt into the wet ingredients and add 2 tablespoons chia seeds; use cow’s milk or soy milk for higher protein.
Common Questions & Answers
Q: Can I make this dairy-free and vegan?
A: Yes — use plant-based milk (almond, oat, soy) and agave or maple syrup; the base is already vegan-friendly.
Q: My baked oatmeal is too dry or too wet. What do I adjust?
A: If too dry, increase milk by 1/4 cup next time or add a mashed banana. If too wet, bake 5–8 minutes longer or reduce the milk by 2 tablespoons.
Q: Can I use frozen berries?
A: Yes. Fold them in frozen to reduce color bleeding; you may need an extra minute or two of baking time.
Q: How can I increase protein?
A: Use soy or cow’s milk, add Greek yogurt to servings, fold in protein powder (vanilla works well), or top with nut butter.
Q: Is it safe to freeze and reheat?
A: Absolutely — freeze in individual portions for up to 2–3 months and thaw in the fridge or reheat from frozen in the oven.
