This sliceable baked oatmeal features layers of fresh blueberries, bananas, and a simple almond butter drizzle. This recipe is perfect for breakfast meal prep!
If you're looking to meal prep breakfast or snacks for a few days, blueberry baked oatmeal is a great option! It's also easy to mix up on slow weekend mornings, and has a lot of options for variations.
My take on baked oatmeal is sliceable, gently sweet, and features both bananas and blueberries. The best part is the almond butter drizzle on top.
The oatmeal slices freeze well and are a great way to start your day, but I also like it as a snack.
If you're looking for softer baked oatmeal, I recommend my pumpkin baked oatmeal recipe instead.

About this recipe
- Time: Requires 10 minutes of active time and 35 minutes of cooking time.
- Makes 6 servings. Freezes well!
- Equipment: All you need is an 8x8-inch or similarly sized baking dish and a mixing bowl.
- Flavors: Banana and blueberry are the main flavors, with a hint of cinnamon and maple syrup.
Ingredients
- Rolled oats: Also called old-fashioned oats. This recipe does not work with Instant oats or Steel cut oats because they require different cooking times.
- Milk: Soy milk is my go-to milk, but cow's milk, oat milk, almond milk, all work here.
- Blueberries & bananas: Fresh or frozen blueberries work. If using frozen bananas, I recommend thawing them first. Choose ripe bananas for the sweetest flavor.
- Maple syrup: Honey also works. Granulated or brown sugar don't work as direct swaps with maple syrup. If you want sweeter oatmeal, I recommend adding a sprinkle of sugar (or maple syrup, etc.) after baking.
- Eggs: This helps with the oatmeal structure and makes it more sliceable.
- Hemp hearts: Adds extra protein and is an easy way to boost nutrition, but this ingredient is optional.
- Flax eggs: Same as the hemp hearts, this nutrient boost is optional.
- Almond butter: While the almond butter drizzle is optional, I think it's the best part. Combine almond butter with powdered sugar and vanilla extract for a punch of sweetness and toastiness.
Step-by-step photos
This recipe can be as easy as dump & bake, but I like to layer the bananas evenly. It's a nice visual affect, but it's also just a nice way to make sure the banana slices are evenly distributed between bites.
The easiest way to do this is to mix up the oatmeal in a separate bowl and add half, top with bananas, then add the rest. Another option (seen below) is to push the bananas into the oatmeal.
- In an 8x8-inch or similarly sized baking dish, stir together the dry ingredients. In a liquid measuring cup, stir together the wet ingredients. Combine the two.
- Push slices of banana into the oatmeal so that they are at least partially covered.
- Top with blueberries and sliced almonds. Bake until golden, firm, and pulling away from the edges of the pan.
- Top with the almond drizzle and extra banana slices. Let cool before slicing.
Storage notes
- Keep leftover baked oatmeal in the fridge for up to 5 days.
- Reheat slices of baked oatmeal in the microwave, or enjoy chilled. I like to add a splash of milk when reheating, as it softens the oatmeal.
- Leftover oatmeal freezes well! Wrap individual slices in foil and place in an airtight container. Thaw frozen oatmeal in the microwave or let thaw overnight in the fridge before reheating.

Blueberry Banana Oatmeal Bars with Almond Drizzle
Equipment
- 8x8-inch baking dish or similarly sized baking dish
Ingredients
Oatmeal Ingredients
- 3 cups rolled oats old-fashioned oats
- 2 tablespoons ground flax seed
- 2 tablespoons hemp hearts optional
- 1 teaspoon baking powder
- 1 teaspoon cinnamon
- ½ teaspoon table salt
- 1 ¼ cups milk I use plain soy milk but any kind works
- 2 large eggs
- ¼ cup maple syrup honey also works
- 2 tablespoons canola oil plus more for greasing the baking dish
- 2 ripe bananas sliced into coins
- 1 cup fresh blueberries
- ⅓ cup sliced almonds optional
Almond Drizzle
- 3 tablespoons milk more as needed (note: can use soy milk)
- 3 tablespoons almond butter
- 2 tablespoons powdered sugar
- ¼ teaspoon vanilla extract
Instructions
- Preheat the oven to 350°F. Lightly oil an 8x8 inch or similarly sized baking dish.
- In a large mixing bowl, whisk together the oats, ground flax seed, hemp hearts, baking powder, cinnamon, and salt. In a separate bowl, whisk together the milk, eggs, maple syrup, and oil. Pour wet ingredients into the dry ingredients, whisking until just combined.
- Spread out half of the oatmeal batter in the oiled 8x8 inch dish. Top with sliced bananas. Cover up the bananas with the remaining batter (it’s okay if they aren’t 100% covered), then top with the blueberries and almonds.
- Bake at 350°F for 35 to 40 minutes, or until firm in the center. A fork or toothpick inserted into the center of the oatmeal should come out clean.
- Meanwhile, make the almond butter drizzle. In a small bowl, whisk together the milk, almond butter, powdered sugar, and vanilla extract. It should be a smooth, pourable-able consistency similar to melted chocolate. Add additional milk as needed.
- Let the oatmeal bars cool at least 10 minutes before drizzling with the almond butter. Slice into 6 rectangles to serve.

Notes
- For a quicker version, the oatmeal can be mixed up directly in the baking dish. Push the banana slices into the oatmeal, then top with the blueberries. The layers won't be as perfect, but you'll have one less dish to clean.
- Frozen blueberries work in place of fresh. Thaw the blueberries before adding to the oatmeal.
- I don't recommend replacing maple syrup with granulated or brown sugar because it could affect the baked oatmeal texture.
- The almond butter drizzle is optional but really worth it! Peanut butter also works, if you don't have almond butter on hand.
- Keep leftover slices refrigerated. Leftover oatmeal freezes well! Wrap individual slices in foil and place in an airtight container. Thaw frozen oatmeal in the microwave or let thaw overnight in the fridge before reheating.

Delicious! I had bananas and blueberries needing to be used and this recipe was perfect. Subbed chia seeds for the hemp and flax I did not have, and maple in the drizzle in place of powdered sugar. Did the layering method and it looks as great as it tastes!
