High Protein Banana Bread Blueberry Baked Oatmeal

Jump to Recipe

this is one of those recipes that makes you stop mid-bite and think, wait… this is actually baked oats?

because the texture lands somewhere between banana bread and a fluffy snack cake but with huge portions, solid protein, and macros that actually make sense.

if you’re into volume eating, easy meal prep, and recipes that feel indulgent without being heavy, this one checks every box.

taste + texture

these baked oats are:

• softly sweet from ripe bananas only
• studded with juicy blueberries in every bite
• light, fluffy, and tall, not dense or gummy

there’s no added sugar here. all the sweetness comes naturally from bananas and berries, which makes this feel nourishing without tasting bland or “healthy.”

the crumb is more much more banana-bread-like than oatmeal-like, thanks to the eggs, yogurt, and double leavening.

the top domes beautifully, the inside stays moist, and each slice feels substantial without being heavy.

this is the kind of recipe that feels cozy and nostalgic, but still works for breakfast, a post-workout snack, or an afternoon “something sweet but not too sweet” moment.

why this is fantastic for meal prep

this is one of my favorite kinds of meal prep recipes because:

• it’s made in an 8 x 8 pan, so the pieces are big
• it holds up beautifully in the fridge
• the flavor actually gets better after day one

each slice is large, filling, and satisfying, which means you don’t need to pair it with much else to feel full. it’s easy to grab, easy to reheat, and easy to eat cold if you’re rushing out the door.

let’s talk macros (and volume eating)

yes, these are huge pieces for the calories.

each serving (¼ of the pan) comes in around:

• ~300–310 calories
• ~17–18g protein
• ~34–36g carbs
• ~6–7g fiber

for a slice this size, that’s impressive. the combination of protein, fiber, and volume makes this incredibly satisfying, which is exactly what you want if you’re trying to eat in a way that feels abundant & not restrictive.

this is volume eating done right: big portions, real ingredients, and no sad “diet” vibes.

one-pan, no blender, no fuss

this recipe is intentionally simple.

everything is mixed directly in the 8 x 8 pan:

• mash the bananas
• whisk in the eggs
• stir in the rest
• bake

no blender. no food processor. no extra bowls. it’s the kind of recipe you can make half-awake on a sunday and still feel accomplished.

add-in and swap options

this recipe is flexible and forgiving. you can easily:

• swap blueberries for raspberries, chopped strawberries, or diced apples
• add chopped walnuts or pecans for crunch
• sprinkle chocolate chips on top for a banana-bread-meets-dessert vibe
• add lemon zest for a bright banana-blueberry twist

you can also make it sweeter with a drizzle of honey or maple syrup on top after baking, if desired. i do recommend if you like sweeter banana bread because this does not have added sugar.

storage + reheating

• store sliced baked oats in an airtight container in the fridge for 4–5 days
• enjoy cold, room temp, or warmed
• reheat in the microwave for ~20–30 seconds for a cozy banana-bread feel

this is a great recipe to bake once and enjoy all week.
