This baked blueberry oatmeal is a warm and cozy breakfast that’s super easy to make! With juicy blueberries and hearty oats, it’s like a hug in a bowl.
You can enjoy it fresh from the oven or save some for later. I love having it with a splash of milk on top—so good! Plus, it makes my mornings feel special without any fuss.
Key Ingredients & Substitutions
Old-fashioned rolled oats: These oats provide the perfect texture for baked oatmeal. Quick oats can be used if that’s all you have, but they may result in a mushier texture.
Baking powder: Essential for making the oatmeal rise and become fluffy. If you run out, you can use baking soda instead, but increase the acid (like a splash of vinegar or lemon juice) in the recipe.
Cinnamon: This adds warmth and depth of flavor. If you’re not a fan of cinnamon, you can swap it out for nutmeg or simply leave it out entirely.
Maple syrup or honey: Both sweeteners work well here. If you prefer, you can use agave nectar or a sugar substitute like stevia, adjusting the amount to taste.
Butter or coconut oil: These fats help keep the oatmeal moist. Use whichever you prefer! For a dairy-free version, go with coconut oil.
How Do I Ensure My Baked Oatmeal Comes Out Perfectly Set?
To get that nice, set texture for your baked oatmeal, follow these steps:
- Mix your wet and dry ingredients separately and then combine them gently. Don’t over stir—this can make the oats gummy.
- Make sure to keep an eye on the baking time. Ovens can vary, so check if the edges are slightly golden and the center is firm.
- If you’re using frozen blueberries, there’s no need to thaw them. Just fold them in while they’re still frozen to avoid excess moisture.
Allow the oatmeal to cool a bit before slicing; it will continue to firm up as it cools. Enjoy your cozy breakfast!

- 1/4 teaspoon salt
- 2 large eggs

How Much Time Will You Need?
This recipe takes about 10 minutes of prep time and 35-40 minutes to bake. After baking, you’ll want to let it cool for a few minutes before slicing. Altogether, you’re looking at around 50 minutes to enjoy this delicious breakfast treat!
Step-by-Step Instructions:
1. Preheat and Prepare:
Start by preheating your oven to 375°F (190°C). Grease or line an 8×8-inch baking dish with parchment paper to prevent sticking.
2. Combine Dry Ingredients:
In a large bowl, mix the rolled oats, baking powder, ground cinnamon, and salt. Make sure everything is well-combined for even flavor throughout the oatmeal.
3. Whisk Wet Ingredients:
In another bowl, whisk together the eggs, milk, maple syrup (or honey), vanilla extract, and melted butter (or coconut oil) until everything is smooth and well blended.
4. Mix It Together:
Pour the wet mixture into the bowl with the dry ingredients. Stir gently until everything is mixed. Don’t overmix—just blend until there are no dry patches left.
5. Fold in Blueberries:
Gently fold in the blueberries, making sure to save a handful to sprinkle on top before baking. This will make for a pretty presentation!
6. Bake:
Pour the mixture into your prepared baking dish and smooth the surface with a spatula. Sprinkle the reserved blueberries on top, and pop it into the oven.
7. Cool and Serve:
Let the baked oatmeal cool for about 5-10 minutes before slicing it into squares. Serve warm, and feel free to add a splash of milk or a dollop of yogurt for extra creaminess!
Enjoy your hearty and delicious baked blueberry oatmeal—perfect for a cozy morning! It’s sure to become a breakfast favorite!
Can I Use Quick Oats Instead of Rolled Oats?
Yes, you can use quick oats, but keep in mind that the texture may be softer and less chewy compared to using rolled oats. Adjust the baking time slightly, as quick oats might cook a bit faster.
How Can I Store Leftover Baked Blueberry Oatmeal?
Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. You can reheat it in the microwave or oven, adding a splash of milk to keep it moist.
Can I Make This Recipe Vegan?
Absolutely! To make it vegan, simply replace the eggs with flaxseed eggs (1 tablespoon flaxseed meal mixed with 2.5 tablespoons of water per egg) and use a plant-based milk and coconut oil instead of butter.
What Other Fruits Can I Use in This Recipe?
You can easily swap out blueberries for other fruits like raspberries, chopped apples, or bananas. Just ensure that any fresh fruit you use is well-drained to avoid excess moisture.
