Ingredients
- Mashed bananas: You will need super ripe, spotty bananas so they mash easily and provide natural sweetness.
- Nut butter: Almond butter works beautifully, but any well-mixed nut butter will do.
- Rolled oats: Old-fashioned rolled oats provide the best texture and structure for these bars.
- Cinnamon: Ground cinnamon adds a warm, cozy flavor profile to the oats.
- Vanilla: Real vanilla extract is recommended for the most authentic flavor.
- Maple syrup: Ensure you use real maple syrup rather than pancake syrup for the best results.
- Chocolate chips: Use your favorite variety, such as semi-sweet, dark, or mini chocolate chips.
- Salt: A pinch of salt balances the sweetness and enhances the other flavors.
Step-by-Step Instructions
- Prepare the oven and pan: Preheat your oven to 350°F. Line a 9×9-inch baking pan with parchment paper to ensure the bars do not stick.
- Combine the ingredients: In a large mixing bowl, add the mashed bananas, nut butter, rolled oats, cinnamon, vanilla extract, maple syrup, chocolate chips, and salt.
- Mix thoroughly: Stir all the ingredients together until they are well combined and the oats are evenly coated.
- Layer the mixture: Transfer the mixture into your prepared baking pan. Use a spatula to flatten it into an even layer. You can sprinkle a few extra chocolate chips on top if desired.
- Bake: Place the pan in the oven and bake for 18 to 20 minutes. The bars are done when the edges are golden brown and the center appears set.
- Cool and cut: Remove the pan from the oven and allow the bars to cool completely in the pan. This is a crucial step as the bars firm up as they cool. Once cooled, slice them into squares.

Expert Tips / Pro Tips
To get the best results with your Banana Oatmeal Bars, keep these tips in mind. First, the riper the bananas, the better the flavor; look for bananas that are heavily spotted or even brown. If you find your parchment paper is sliding around while you try to spread the mixture, use small binder clips to hold the paper against the sides of the pan (just remember to remove them before putting the pan in the oven). Most importantly, resist the urge to cut the bars while they are still warm. They need that cooling time to set properly so they don’t crumble.
This recipe is a fantastic base for experimentation. If you want to change the flavor profile, try using peanut butter or cashew butter instead of almond butter. For extra texture, you can add mix-ins like chopped walnuts, pumpkin seeds, sunflower seeds, or dried fruit like raisins or cranberries. If you are looking for a lower-sugar option, you can reduce the amount of chocolate chips or use a sugar-free alternative.
Serving Suggestions
These bars are versatile enough to be eaten at any time of day. For breakfast, pair a bar with a side of Greek yogurt or a hard-boiled egg for extra protein. They also make a fantastic pre-workout snack or an afternoon treat alongside a hot cup of coffee or tea. Because they are sturdy, they are also perfect for packing in school or work lunchboxes.
Storage: Once the bars have cooled and been sliced, store them in an airtight container. They will stay fresh on the countertop for about 2 days or in the refrigerator for up to 5 days.
Freezing: These bars freeze exceptionally well. Wrap individual bars in plastic wrap and place them in a freezer-safe bag. They can be frozen for 2 to 3 months.
Reheating: If you prefer a warm snack, you can pop a bar in the microwave for 10 to 15 seconds. If frozen, let them thaw overnight in the refrigerator before serving.

FAQ
What kind of nut butter works best?
Peanut butter is a classic choice that pairs perfectly with banana, but almond butter and cashew butter are also excellent options. If you have a nut allergy, you can try using sunflower seed butter.
How can I ripen my bananas quickly?
If your bananas aren’t quite ready, place them in a paper bag for 1 to 2 days. The trapped ethylene gas will speed up the ripening process. Adding an apple to the bag can make it happen even faster!
Can I use steel-cut oats for this recipe?
No, steel-cut oats will not work for this recipe as they require much more liquid and a longer cooking time. Stick with old-fashioned rolled oats for the best texture.
