Save I started making these bars on Sunday nights after realizing my weekday mornings were a blur of missed breakfast and regret. The smell of bananas baking with cinnamon now means I've actually planned ahead for once. They're sturdy enough to toss in a bag, soft enough to eat half-awake, and they've saved me from the drive-thru more times than I can count. My kitchen always smells like a bakery when these come out of the oven. It's become my favorite kind of Sunday ritual.
The first time I brought these to work, a coworker asked if I'd bought them from some fancy cafe. I didn't correct her right away because it felt good to look like I had my life together. Later I admitted they took less than an hour to make, and now she texts me every time she bakes a batch. It's funny how a simple recipe can become a small point of pride.
Ingredients
- Old-fashioned rolled oats: These give the bars their chewy, hearty texture and keep you full longer than quick oats ever could.
- Vanilla protein powder: I use this to sneak in extra protein without the chalky taste, just make sure it's a flavor you actually like.
- Ground cinnamon: A half teaspoon is enough to make the whole kitchen smell warm and cozy without overpowering the fruit.
- Salt: Don't skip it, even a pinch makes the sweetness taste deeper and more balanced.
- Baking powder: This gives the bars a slight lift so they're tender instead of dense.
- Ripe bananas: The riper, the better, those brown-spotted ones are perfect and add natural sweetness.
- Honey or pure maple syrup: Either one works beautifully, I go back and forth depending on what's in the pantry.
- Unsweetened applesauce: It keeps the bars moist without adding extra oil or butter, and you can't taste it at all.
- Eggs: They bind everything together and give the bars structure so they slice cleanly.
- Pure vanilla extract: Just a teaspoon makes the whole thing taste more homemade and less like a protein bar.
- Melted coconut oil or unsalted butter: I prefer coconut oil for a subtle flavor, but butter works if that's what you have.
- Fresh or frozen blueberries: Frozen ones are easier because you don't have to worry about them going bad, just don't thaw them first.
Instructions
- Preheat and prep the pan:
- Set your oven to 350°F and line an 8x8-inch pan with parchment paper, letting the edges hang over so you can lift the whole thing out later. This step saves you from wrestling with a spatula and ruining your perfect bars.
- Mix the dry ingredients:
- Whisk together the oats, protein powder, cinnamon, salt, and baking powder in a large bowl until everything looks evenly combined. It only takes a minute and ensures you won't get pockets of baking powder or cinnamon.
- Combine the wet ingredients:
- Mash the bananas in another bowl until they're smooth and creamy, then whisk in the honey, applesauce, eggs, vanilla, and melted oil. The mixture should look glossy and thick.
- Bring it all together:
- Pour the wet ingredients into the dry and stir gently until just combined, don't overmix or the bars can turn out tough. The batter will be thick and a little lumpy, that's exactly right.
- Fold in the blueberries:
- Add the blueberries and fold them in carefully, especially if they're frozen, so they don't break apart and turn everything purple. A few swirls with a spatula is all you need.
- Spread and bake:
- Spread the batter evenly into the prepared pan and smooth the top with the back of a spoon. Bake for 28 to 32 minutes, until the edges are golden and a toothpick comes out clean.
- Cool and slice:
- Let the bars cool completely in the pan before lifting them out by the parchment. Cut into 12 squares and try not to eat three of them right away.
Save I keep a stash of these in the fridge and grab one on my way out the door most mornings. My kids started asking for them instead of cereal, which feels like a quiet parenting win. There's something satisfying about having homemade food ready to go when life gets chaotic.
Storing and Meal Prep
These bars keep at room temperature in an airtight container for up to three days, but I usually refrigerate them because I like them cold. They last a full week in the fridge and even longer in the freezer if you wrap them individually. On Sunday I bake a batch, slice them up, and stack them in a container so I don't have to think about breakfast until the following weekend.
Swaps and Substitutions
If you don't have protein powder or just don't want to use it, swap it out for the same amount of oat flour and the bars will still turn out great. You can use any milk or plant-based protein powder you like, just make sure it's a flavor that pairs well with banana and blueberry. I've made these dairy-free by using coconut oil and a vegan protein powder, and nobody could tell the difference.
Mix-Ins and Variations
Sometimes I throw in a handful of chopped walnuts or sliced almonds for extra crunch, and it adds a nice texture contrast. You can swap the blueberries for raspberries, chopped strawberries, or even chocolate chips if you're feeling indulgent. A tablespoon of chia seeds or flaxseed meal mixed into the batter adds a little extra fiber and makes them even more filling.
- Try adding a handful of shredded coconut for a tropical twist.
- A pinch of nutmeg or cardamom in the dry ingredients gives them a subtle warmth.
- Drizzle with almond butter or peanut butter right before eating for an extra protein boost.
Save These bars have become one of those recipes I don't even think about anymore, I just make them. They're easy, reliable, and they've turned my mornings into something a little less frantic.
