Ingredients & Substitutions

As promised, you only need a few simple ingredients to make these chocolate chip peanut butter oatmeal bars. Here’s what to grab:

  • Bananas – This is one instance where the browner your bananas are, the better! While I recommend measuring out the banana to make sure your ratios are correct, you can count on needing about 3.
  • Natural Peanut Butter – Opt for a brand that has just peanuts and salt as the ingredients. Avoiding the added sugar and hydrogenated oils from conventional peanut butter keeps these banana oatmeal bars virtuous. You could alternatively use almond butter or cashew butter!
  • Pure Maple Syrup – Don’t reach for Aunt Jemima or Log Cabin — those maple-flavored syrup blends are primarily corn syrup. Instead, reach for the real stuff that comes from trees so you can reap all the health benefits.
  • Vanilla Extract – While “vanilla” is often used to describe things that are boring or blase, true vanilla flavor is anything but. With gorgeous complexity and deep warmth, this single ingredient takes these banana peanut butter bars over the top. Feel free to swap in an equal amount of vanilla paste or vanilla powder, or use half as much ground vanilla bean instead.
  • Egg – For binding the banana oatmeal breakfast bar batter. Make sure to let your egg come to room temperature so it’s easier to mix into the batter.
  • Old-Fashioned Oats – Also known as “rolled oats,” these delicious whole grains add a chewy, toothsome quality that is absolutely crave-worthy. Better yet, the added fiber and nutrients help to keep you feeling powered up for your day! Quick oats should work too.
  • Cinnamon – For a touch of warmth that evokes banana bread vibes. Feel free to experiment with other warming spices like ginger, cardamom, allspice, clove, or pumpkin pie spice.
  • Baking Powder – This powdered raising agent gives these healthy chocolate chip oatmeal bars the perfect tender-crumbed consistency. Note that it begins to work as soon as it touches liquid, so don’t mix up your batter before preheating the oven or you’ll miss out on some of the leavening power.
  • Salt – Strange though it may seem, salt can help enhance the sweet flavors of your favorite desserts.
  • Dark Chocolate Chips – I prefer reaching for 70% cocoa or above for the greatest nutritional benefits.

As if a short ingredient list weren’t enough to love, you also only need a few basic pieces of kitchen equipment to make my peanut butter oatmeal banana bars. Here’s what to grab:

  • Large Bowl
  • Measuring Cups & Spoons – Baking is all about precision. Make sure you get consistently delicious results by measuring everything before adding it!
  • Silicone Spatula – Or any flexible scraper to help you get every last drop of peanut butter banana goodness into the baking tin.
  • Parchment Paper – Using parchment paper to line your baking tin ensures your peanut butter banana bars come out of the tin without leaving any yumminess behind.
  • 8×8 Baking Tin – You can also use a 9” round cake tin if you prefer serving them in wedges instead of squares.
  • Cooling Rack – If you don’t have an assigned cooling rack, you can always pull the rack from your toaster oven. 
  • Chef’s Knife – Or a knife that’s sharp and long enough to cut your peanut butter chocolate oatmeal bars into grab-and-go portions.

How To Make Healthy Peanut Butter Oatmeal Bars

This easy peanut butter oatmeal bars recipe comes together in a flash. Here’s how:

Step 6: Cool & Slice. Remove from the oven and let cool for at least 20 minutes before cutting into squares. You can do 9 or 16 bars.

Optional Variations & Dietary Adaptations

As much as I love these naturally sweetened peanut butter chocolate chip oatmeal bars just the way they’re written, you’re welcome to tinker with the recipe to make it work for you. Here are a few variations worth considering:

  • Gluten-Free – To make these oat chocolate peanut butter bars celiac-friendly, make sure to reach for certified gluten-free rolled oats.
  • Nut-Free – Love the concept of these breakfast oat bars, but can’t do nuts? No worries! You can easily swap in sunflower seed butter or tahini for the peanut butter. If seeds are also a no-no, consider using less healthy (but wildly delicious) cookie butter or granola butter instead.
  • Banana-Free – Don’t love bananas, or don’t have any on hand? Feel free to swap in canned pumpkin purée or plain mashed sweet potatoes. You can also help fill out the recipe (say, if you only have 2 ripe bananas) by making up the difference with unsweetened applesauce. 
  • Vegan – You’re welcome to use a flax egg (1 Tablespoon Flax Seed or Flax Meal + 3 Tablespoons Water + Stir + 10 Minute Rest) to make vegan-friendly peanut butter oatmeal chocolate chip bars.
  • Different Mix-Ins – Don’t feel like you have to add chocolate chips just because I’m a chocoholic. Try swapping in other yummy add-ins like chewy chopped dates, crunchy toasted nuts, or plain roasted cacao nibs instead.

Expert Tips

  • Patience is a virtue. Allow the banana oatmeal breakfast bars to cool before cutting into them so they don’t fall apart.
  • Use natural peanut butter so you get all the nutritional benefits without any added sugars or hydrogenated fats. Classic peanut butter also has a different make-up and consistency than natural peanut butter, so it will bake differently and the results may not be the same.
  • Opt for the ripest, spottiest bananas you can find for the best flavor. This will add the most delicious natural sweetness.
  • Don’t have ripe bananas on hand? No problem! One of my favorite food, baking, and cooking hacks is oven ripening my bananas. All you have to do is place the bananas, unpeeled, on a parchment paper or aluminum foil lined baking tray. Bake in the oven at 300 degrees for 20-30 minutes until the bananas are a dark brown, black color and the juices are oozing out. Let the bananas cool, peel and mash, and then you’re good to go!

Serving Suggestions

My favorite thing about these banana oatmeal bars is that they are delicious enough for dessert, but nutritious enough for breakfast. Plus they are quick enough for an easy snack! Now that is versatility.

Whichever way you enjoy one of these banana bars – as an afternoon snack, sweet breakfast, or healthy dessert – I can guarantee it will be delicious.

You can enjoy at room temperature, warmed up in the microwave, or a little chilled straight from the fridge. My favorite way to serve them though is warm with a delicious smear of creamy peanut butter on top. So yummy!

How long do peanut butter banana oatmeal bars last? What’s the best way to store them?

These healthy peanut butter bars with oatmeal will keep in an airtight container at room temp for 1-2 days. If you’d like to extend their shelf life to about a week, move them to the fridge.

Alternatively, they can also be frozen for up to 6 weeks.

How are these banana oatmeal chocolate chip bars healthy?

They are low in refined sugars, provide essential nutrients, and offer a balanced combination of healthy fats, fiber, and protein. 

First and foremost, we have bananas. These starchy fruits are rich in essential vitamins and minerals, add natural sweetness to the bars without the need for excessive amounts of refined sugar, plus provide dietary fiber.

Next up, we have peanut butter, which adds a dose of healthy fats to the recipe.  Additionally, peanut butter is a good source of plant-based protein, which helps to keep you fueled up till lunchtime.

Rolled oats are another nutritional powerhouse. They are a great source of complex carbohydrates and dietary fiber, and are also known for their cholesterol-lowering properties. They also happen to be rich in vitamins, minerals, and antioxidants.

As far as sugar is concerned we add just a touch of maple syrup for sweetness, which is a natural alternative to refined sugars.

Finally, let’s not forget about the dark chocolate chips! Dark chocolate contains higher amounts of cocoa and less added sugar compared to milk chocolate. It is packed with antioxidants that can potentially improve heart health and boost mood.
