With less than 10 simple ingredients, you probably have everything you need to make a batch right now! I love having them on hand as a grab and go workout snack.
These healthy oatmeal bars are vegan, dairy free, egg free, and gluten free (when using certified gluten-free oats).
Ingredients You’ll Need
Bananas: you’ll need three bananas for these peanut butter oatmeal bars. For sweeter bars, use extra ripe bananas. Bananas that are more ripe also mash better which is helpful for this recipe.
Oats: I like the texture of old-fashioned oats for this delicious recipe. I haven’t made it with quick oats, but I think it should work. You just want to avoid using steel cut oats.
Peanut Butter: peanut butter and banana are one of my favorite combos. The creamy peanut butter here adds some flavor as well helping to bind to dough together since we aren’t using any eggs in this vegan recipe. Crunchy peanut butter and well stirred natural peanut butter also work in this recipe.
Maple Syrup: adds natural sweetness to these bars.
Baking Powder: gives these bars just a little bit of lift.
Chocolate Chips: I like to use dark chocolate chips or the mini semi-sweet chocolate chips from Enjoy Life. You can use any favorite vegan chocolate chips you have on hand. Don’t have chocolate chips? You could also add nuts, dried fruit, or pumpkin seeds instead.
Step by Step
Step One: Add your bananas to a large mixing bowl and mash well with a fork or a handheld mixer.
Step Two: Add the rest of the ingredients to the large bowl with the mashed bananas and stir well to combine.
Step Three: Transfer the batter to an 8×8 inch baking dish lined with parchment paper. (Spray well with cooking spray if not in using parchment.) Bake for 25-30 minutes at 350 degrees Fahrenheit until golden brown and firm.
Step Four: Allow the cooked bars to cool completely before cutting. (For neater cuts, chill in the fridge before cutting into pieces.) Store these peanut butter banana bars in an airtight container in the fridge or freezer.
Use extra ripe bananas: kind of like banana bread, using overripe bananas is best for this recipe since they mash better and add more sweetness.
Line your baking dish with parchment: to make it easier to cut and store these bars, I like to line my baking pan with parchment paper so I can then just lift the bars out of the pan with the paper once cool.
Allow to cool completely: allow these oatmeal breakfast bars to cool completely before cutting them or else they will crumble a bit.
Yes! This bar recipe also works well with almond butter or cashew butter.
