You’ll adore these banana oatmeal bars for so many fantastic reasons. They truly simplify healthy eating.

  • They make an ultimate healthy snack, full of fiber and natural sweetness.
  • The process is super simple, requiring just one bowl and minimal fuss.

Ingredients

Gather these simple ingredients to create your batch of delicious banana oatmeal bars:

  • 1½ cups mashed bananas (approximately 3 ripe bananas)
  • ½ cup nut butter (almond, peanut, or cashew work well)
  • 2 cups rolled oats (old-fashioned oats are best)
  • 1 teaspoon cinnamon
  • 1 teaspoon vanilla extract
  • 3 tablespoons maple syrup (or other liquid sweetener)
  • 1 cup chocolate chips (dark, semi-sweet, or dairy-free)
  • ½ teaspoon salt

Notes & Substitutions

Always use very ripe bananas for the best flavor and sweetness in these banana oatmeal bars. Overripe bananas, often with brown spots, mash easily and add moisture. According to culinary resources, ripe bananas are ideal for baking as they contribute natural sweetness and a moist texture. You can use any favorite nut butter, such as almond butter for a milder taste or peanut butter for a richer flavor. For a nut-free option, try sunflower seed butter. Maple syrup adds lovely sweetness; agave nectar or honey are great alternatives if you prefer. Rolled oats give these oat bars a chewy texture, but quick oats can also work, though they might make the bars slightly denser. Feel free to use dark chocolate chips, milk chocolate, or even white chocolate chips. A pinch of nutmeg or a dash of cardamom makes a lovely optional flavor enhancer.

Equipment

You only need a few basic tools to prepare these simple baked oatmeal bars:

  • Large mixing bowl
  • Mashing fork or potato masher
  • Spatula or spoon
  • Measuring cups and spoons
  • 9×9 inch baking pan
  • Parchment paper

Instructions

Let’s create your delicious banana oatmeal bars with these straightforward steps:

  1. Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Line a 9×9 inch baking pan with parchment paper, leaving an overhang on the sides. This makes it much easier to lift the cooled bars out later.
  2. Mash Bananas: In a large mixing bowl, thoroughly mash your ripe bananas until they are smooth with only a few small lumps remaining. Ensure they are well broken down to evenly distribute their sweetness and moisture.
  3. Combine Wet Ingredients: Add the nut butter, vanilla extract, and maple syrup to the mashed bananas. Stir everything together until the mixture is well combined and has a smooth, creamy consistency.
  4. Mix in Dry Ingredients: Now, add the rolled oats, cinnamon, and salt to the wet banana mixture. Stir gently until all the dry ingredients are fully incorporated and the oats are moistened. Try not to overmix, but ensure no dry spots remain.
  5. Fold in Chocolate Chips: Gently fold in the chocolate chips. Distribute them evenly throughout the mixture so every bite of your banana oatmeal bars gets a lovely bit of chocolate.
  6. Press into Pan: Transfer the entire mixture to your prepared 9×9 inch baking pan. Use the back of a spoon or your hands to press the mixture down firmly and evenly into a flat layer. Make sure it reaches all corners. You can sprinkle a few extra chocolate chips on top for an appealing finish.
  7. Bake the Bars: Bake for 18 to 20 minutes, or until the edges appear golden brown and the center of the bars looks set. The bars should feel firm to the touch when gently pressed.
  8. Cool Completely: Remove the pan from the oven and place it on a wire rack. It is crucial to allow the banana oatmeal bars to cool completely in the pan before attempting to slice them. This ensures they set properly and don’t crumble. Once fully cooled, use the parchment paper overhang to lift the entire slab out and slice it into 16 squares.

Pro Tips & Troubleshooting

Achieve perfect banana oatmeal bars every time with these helpful tips. Always use very ripe bananas; they provide natural sweetness and necessary moisture for texture. Proper cooling is crucial for setting; patience ensures your bars hold their shape beautifully. Avoid over-baking, as this can lead to dry or crumbly bars. The edges should be golden, not dark brown. Using parchment paper with an overhang makes removal and slicing effortless. For even bars, press the mixture firmly and uniformly into the pan.

You can also boost protein by adding a scoop of vanilla or unflavored protein powder to the mix before baking.
