Ingredients You’ll Need
I absolutely love how the ingredients for Blueberry Baked Oatmeal are straightforward, yet each one brings something special to the table. From the hearty oats that create the foundation, to the bananas and blueberries that provide natural sweetness and vibrant color, every item here has a role in making this breakfast a star.
- Rolled oats: The base of this dish, oats bring chewy texture and earthy flavor while keeping things wholesome and filling.
- Almond butter: Adds rich creaminess and a touch of nutty flavor—feel free to use your favorite nut or seed butter for a twist.
- Bananas: Mashed bananas act as a natural sweetener and binder, making each bite moist and just the right amount of sweet.
- Blueberries: Bursts of juicy, tart sweetness in every bite; you can use fresh or frozen, and any extras make for the perfect topping.
- Optional honey or maple syrup: For those who like it a little sweeter, a drizzle of honey or maple syrup blends right in.
- Milk (if needed): Helps adjust the batter’s consistency for perfect moisture, depending on your bananas or nut butter.
- Mix-ins (like walnuts): Adds a lovely crunch and extra flavor—chopped walnuts are my favorite go-to.
How to Make Blueberry Baked Oatmeal
Step 1: Prep Your Pan and Oven
Start by preheating your oven to 180C or 350F. While it heats up, line an 8×8-inch pan with parchment paper. This simple step ensures your Blueberry Baked Oatmeal will pop right out of the pan without sticking or crumbling, making for super easy cleanup later on.
Step 2: Mix Up the Batter
In a large mixing bowl, combine your mashed bananas, rolled oats, almond butter, and a splash of honey or maple syrup if you like it extra sweet. This is where you set the foundation for the dense and delicious texture! Gently fold in half of your blueberries—using a spatula makes quick work of this, and helps distribute that blueberry goodness evenly.
Step 3: Adjust the Consistency
Once your main ingredients are combined, check the consistency; if it looks too thick, add a little milk until it’s just right. On the other hand, if the mix seems runny, a sprinkle of extra oats will thicken things up. You’re aiming for a thick, scoopable batter that holds together but isn’t dry.
Step 4: Layer and Top
Pour the batter into your lined pan and spread it evenly to the corners. Top with the remaining blueberries and any fun mix-ins you love—think chopped walnuts, pecans, or even a sprinkle of cinnamon. This gives that signature bakery-style look and a boost of texture right on top.
Step 5: Bake to Perfection
Slide your pan into the oven and bake for 15 minutes, or until the edges are golden and a skewer poked into the center comes out just clean. This short baking time keeps the Blueberry Baked Oatmeal chewy and moist in the middle, while firming up the outside just enough.
Step 6: Cool and Serve
After baking, let your Blueberry Baked Oatmeal cool in the pan for about 15 minutes. Then, move it to a wire rack to finish cooling completely. This little patience step ensures clean slices and the best possible texture. Slice into squares and get ready to dig in!
How to Serve Blueberry Baked Oatmeal
Garnishes
A dollop of creamy Greek yogurt, an extra sprinkle of fresh blueberries, or a tiny drizzle of maple syrup on top takes Blueberry Baked Oatmeal straight to irresistible territory. You can even add a pinch of cinnamon or dusting of powdered sugar for bakery-style charm.
Side Dishes
Pair a square of Blueberry Baked Oatmeal with a fresh fruit salad, a tall glass of cold milk, or your favorite smoothie for a balanced, satisfying breakfast. If you’re serving brunch, scramble some eggs on the side or offer crispy bacon for a sweet-savory combo.
Creative Ways to Present
Cut the bars into smaller bite-sized pieces for snack platters or layer them with yogurt and granola for pretty breakfast parfaits. For a grab-and-go treat, wrap individual squares and tuck them in lunch boxes or picnic baskets—Blueberry Baked Oatmeal is just as crowd-pleasing served warm or at room temperature.
Make Ahead and Storage
Storing Leftovers
Keep any extra Blueberry Baked Oatmeal in a sealed container in the refrigerator, where it will stay moist and tasty for up to five days. This makes it perfect for meal prepping a week’s worth of quick breakfasts or healthy snacks.
Freezing
For longer storage, wrap individual squares of Blueberry Baked Oatmeal in plastic wrap, then place them in a freezer bag. Store for up to six months—just be sure to thaw overnight in the fridge before eating or reheating.
Reheating
Need a warm, comforting breakfast? Just pop an oat square in the microwave for 20-30 seconds until warmed through. It comes out soft, chewy, and every bit as delicious as fresh from the oven!
FAQs
Can I use steel-cut oats instead of rolled oats?
Rolled oats offer the perfect tender, chewy texture for Blueberry Baked Oatmeal—steel-cut oats won’t soften enough in the quick bake time. If you only have steel-cut oats, try soaking them overnight first for better results.
What can I use instead of almond butter?
Absolutely! Any nut or seed butter will work beautifully here. Peanut butter gives a classic, nostalgic flavor, while sunflower seed butter keeps things nut-free and deliciously creamy.
Can I make Blueberry Baked Oatmeal vegan?
Yes, this recipe is already vegan if you use plant-based milk and skip honey for maple syrup. It’s naturally egg-free and dairy-free, so it fits perfectly into a plant-powered lifestyle.
How do I make this recipe sweeter?
If you prefer a sweeter bite, add one or two tablespoons of maple syrup or honey to your batter, and consider stirring in a splash of vanilla extract. The ripe bananas also add plenty of natural sweetness.
Is Blueberry Baked Oatmeal good for meal prep?
It’s a meal-prepper’s dream! Make a batch on Sunday, slice it into squares, and enjoy grab-and-go breakfasts or snacks all week long. The texture and flavor hold up wonderfully in the fridge or freezer.
Final Thoughts
There’s just something incredible about a breakfast that’s as healthy as it is crave-worthy, and Blueberry Baked Oatmeal delivers every time. I hope you treat yourself to a warm, gooey square soon, and that it brings as much joy to your mornings as it does to mine!

Instructions
- Preheat the Oven: Set your oven to 180°C/350°F. Line an 8 x 8-inch baking pan with parchment paper to prevent sticking, then set aside.

- Add Blueberries and Adjust Texture: Fold in half of your blueberries gently using a rubber spatula. If your batter feels too thick, add a little milk to loosen it. If it’s too runny, stir in a few extra oats.
- Fill the Pan and Add Toppings: Transfer the batter into the lined baking pan. Sprinkle over the remaining blueberries and any mix-ins you like (such as the chopped walnuts for added crunch).
