How To Make Peanut Butter Banana Oatmeal Bars
These oatmeal banana bars are so easy to make with only a few wholesome ingredients and perfect for using ripe bananas sitting on your kitchen counter.
- Ripe Bananas – the best is to mash the bananas first, then measure the amount in a measuring cup. This ensures the best bar texture and avoids dry bars if your bananas are smaller.
- Maple Syrup – Use classic maple syrup or any liquid sweetener you love, including coconut nectar and agave syrup.
- Peanut Butter – Pick natural peanut butter with no added salt, no added oil, and no added sugar.
- Vanilla Extract
- Old-Fashioned Rolled Oats – You can also use quick oats. The same amount works very well, but the bars have a bit less crunch and texture with quick oats.
- Ground Flaxmeal – golden flaxseed meal has no bitter flavor, and it’s recommended for the best flavor. However, a brown flaxseed meal also works very well if you appreciate its flavor.
Mashing The Bananas
First, peel bananas, place them in a bowl and mash the ripe bananas with a fork or potato masher until it forms a banana puree.
I highly recommend spending a few minutes precisely measuring the mashed bananas to make the bar texture perfect.
Place the mashed bananas into a large bowl. Then, stir in the remaining liquid ingredients: natural peanut butter, maple syrup, and vanilla extract. Stir until well combined.
Fold in the rolled oats, flaxseed meal, and cinnamon, and stir to combine. The batter should be thick and slightly wet but stick together.
If too wet or liquid, you can add an extra 1 to 2 tablespoons of flaxseed meal.
Feel free to add any optional ingredients listed below, like chopped nuts or dark chocolate chips.
Baking The Bars
Press the batter firmly into a square baking pan. Sprinkle extra chocolate chips on top of the bars.
Bake in the center rack of the oven until the bars are golden brown and set on top.
Cool down in the pan for 20 minutes. Then pull out the banana oatmeal bar from the pan using the hanging part of parchment paper.
Cool completely at room temperature before cutting – or if the bars look fragile, you can pop the bar in the fridge 1 hour before cutting to firm up the bars.
Transfer onto a chopping board and cut into 12 long bars.
You can add some delicious ingredients to the batter to turn the recipe into banana bread bars. Add between 1/4 cup to 1/3 cup of some of the below ingredients:
- Chopped Walnuts or pecans – optional but it adds a delicious crunch.
- Chocolate Chips – optional as well, for a boost of sweetness and lovely chocolate flavor.
- Nut-free option – you can swap the nut butter for sun butter or tahini.
- Peanut-free – other nut butter works very well in the recipe, including almond butter, and cashew butter.
- Gluten-free option – use certified gluten-free oats or try quinoa flakes. Note that quinoa flakes are slightly bitter. You may need to roast the quinoa flakes before using them to avoid the bitterness.
