Real talk: I’m not a breakfast person. Coffee? Yes. Food before 10 AM? Hard pass. UNLESS it’s this bake. The ONE morning thing I actually crave, and it’s mostly just stuff I already have hanging out in the pantry anyway.
Five ingredients. One bowl. Bananas keep it sweet, almond butter holds it all together, blueberries go jammy on top. Make it Sunday and you’re set till Wednesday.
Why Ripe Bananas Matter Here
Ripe bananas do the heavy lifting here. They double as natural sweetener AND binder (no eggs in this recipe!)…. so pick ones with brown SPOTS for maximum flavor.
Yellow-without-speckles won’t mash properly and leave you with bitter chunks. Soft, spotted bananas = sweet, smooth batter that holds its shape.
How to Store & Reheat Leftovers
- FRIDGE IT FAST: Cool completely, then store in an airtight container for up to 4 days. (Don’t leave it sitting out longer than 2 hours… food safety first!)
- FREEZE FOR LATER: Slice into portions, wrap each piece in plastic wrap, then tuck into a freezer bag. Stays good for 2 to 3 months.
- MICROWAVE METHOD: Zap one serving for 30 to 60 seconds. A splash of milk revives any dryness. Game over, dry oatmeal!
- OVEN REHEAT: 160°C (325°F) for 8 to 10 minutes, loosely tented with foil. Keeps the top from over-browning.
- TOASTER OVEN OPTION: 5 to 7 minutes at 160°C handles a single slice beautifully. Skip firing up the whole oven!
Topping & Mix-In Ideas
- CHOPPED WALNUTS OR PECANS – scatter on top before baking…. crunch, toasty flavor, done
- DARK CHOCOLATE CHIPS – it’s breakfast! A handful folded in hits different
- GROUND CINNAMON – one teaspoon stirred through the batter for warmth and depth
- CHIA OR FLAX SEEDS – a tablespoon folded in adds fiber, no texture change
- LEMON ZEST – brightens everything, especially with the blueberries (trust me)
- SHREDDED COCONUT – sprinkle on top for a tropical hint and chewy bite
- FROZEN RASPBERRIES – swap or mix with blueberries for a tart punch

Ingredients
- 2 cups old-fashioned oats (use gluten-free if desired)
- 2 large ripe bananas
- 1/2 cup almond butter or other nut/seed butter
- 1/2 cup fresh blueberries
Step 1: Ready the Oven and Pan
Preheat your oven to 180°C (350°F).
Line an 8 x 8-inch baking pan with parchment paper, making sure the paper comes up the sides for easy removal later.
Set the pan aside as you prepare the batter.
Step 2: Combine the Batter Ingredients
- 2 large ripe bananas
- 2 cups old-fashioned oats (use gluten-free if desired)
- 1/2 cup almond butter or other nut/seed butter
- 1/2 cup fresh blueberries (half, folded in at this stage)
In a large mixing bowl, mash the ripe bananas until mostly smooth.
Add the old-fashioned oats and almond butter to the bowl.
If you like a sweeter oatmeal, you can add a tablespoon or two of honey or maple syrup at this stage (optional).
Stir everything together with a spatula until well combined.
Then, gently fold in half of the fresh blueberries, being careful not to crush them.
If the mixture is too thick, add a splash of milk to loosen it; if it’s too thin, mix in a few extra oats.
Step 3: Layer and Bake
- remaining 1/2 cup fresh blueberries (from Step 2)
Transfer the batter to the prepared pan, spreading it into an even layer.
Sprinkle the remaining fresh blueberries and any additional mix-ins you like—such as chopped walnuts—on top.
Bake in the preheated oven for about 15 minutes, or until the edges are golden brown and a skewer inserted in the center comes out just clean.
I like to slightly press the blueberries into the top so they don’t roll off during baking.
Step 4: Cool and Slice
Remove the baked oatmeal from the oven and let it cool in the pan for about 15 minutes.
Then, carefully lift it out using the parchment paper and transfer it to a wire rack to cool completely before slicing and serving.
I find the flavor and texture improve as it cools, so a bit of patience pays off!
