    🍌What you will need:

    Ingredients needed for this recipe which is ripe bananas, peanut butter and oats.

    📓Notes / substitutions

    • Make sure that you are using bananas that are ripe and spotty. As they are the main sweetener in this recipe, you will want them to be super ripe and sweet.
    • Frozen bananas can be used in this recipe, but do defrost them first.
    • To make it gluten-free, use certified gluten-free oats.
    • Both quick oats and rolled oats can be used. Quick oats will yield bars that have less texture.
    • Feel free to substitute the peanut butter with other nut butters like almond butter or cashew butter. To make it nut-free, use sunflower seed butter or pumpkin seed butter instead.
    • If you like more texture and crunch, add in ½ cup of your favorite nuts ! Be sure to chop them up into smaller pieces.

    🍫Optional add-ins

    • If you like your oat bars to be extra sweet, add 2 - 4 tablespoons sweetener of choice. Some of my favorite includes maple syrup, coconut sugar and raw sugar.
    • Add in ¼ - ½ cups of your favorite chocolate chips to jazz things up.
    • Vanilla extract will go really well in this recipe to. I recommend adding about 1 teaspoon.

    🔪How to make

    Start by preheating oven to 180c / 360f . Line or grease a 8x8 square baking pan.

    In a large mixing bowl, mash the bananas until smooth, using a fork or potato masher. It is ok to have a few small chunks here and there.

    Next, add in the peanut butter and mix well. Then, stir in the oats and mix again until the oats are well incorporated.

    Transfer the mixture to the baking pan. Using the back of a spoon or a spatula, smooth out the mixture so that it is evenly distributed.

    Bake it in the oven for 20-25 minutes, or until a toothpick comes out clean and the sides are golden brown.

    Remove it from the oven and let it cool down completely before slicing. Optionally, drizzle on more peanut butter before serving !

    ❔Commonly asked questions

    What is the texture like ?

    They are dense and chewy, yet super moist on the inside, somewhere between the texture of a baked oatmeal and granola bar. They also hold their shape pretty well, making them the perfect portable snack to have with you on the go.

    As the texture is not at all similar to normal cooked oats, I urge anyone who hate oatmeal to give this recipe a try. Who knows, you might like them !

    Do they have to be refrigerated ?

    Depending on the climate, you do have to refrigerate them if they are not consumed within 3-4 days. Simply transfer them to a sealed container and pop them into the fridge. They can be kept there for a week.

    Can I freeze them ?

    Yes, these bars are freezable ! To do so, let them cool down completely first. Then, arrange them on a large plate / tray in a single layer. Pop them into the freezer for 1-2 hours, or until they are frozen.

    You can now transfer them to any storage containers or zip-top bags without worrying that they will be stuck together ! They can be freeze for up to 3 months.

    To heat, let them defrost in the fridge overnight, then heat them in the oven at 180c for 8-10 minutes, or until they are thoroughly warmed. Alternatively, heat frozen bars in the microwave oven for 45-60 seconds.

      Hi,

      Adding cinnamon is a great idea. Any suggestions on amount?

      Also, I would like to add some protein power. And thinking of apple sauce so it is not so dry but I am not sure on amount? Any suggestions?

      Thanks so much

        For cinnamon, you can add up to a teaspoon. Yes, feel free to add protein powder and applesauce! I have yet to try adding applesauce, but you could try adding 1/4 cup. If the mixture appears thick, you can add a splash of milk to it!

      Would pb2 work? Trying to cut down on fat.

        Yes, but you will need to rehydrate your pb2 first. You could try 1/2 cup of pb2 with 8-10 tablespoons of water.

      Such a simple yet delicious treat!
      I had a lot of bananas that I needed to use up, stumbled upon this recipe and decided to make it!
      Added some chocolate chips, drizzled some peanut butter on top once cooled, devoured it!

      Can chia seeds or pum[kin seeds be added to the recipe to ramp up the protein content?

      Reply
      • Meesha

        January 03, 2022 at 10:23 am

        Yes, definitely! You can add about 1-2 tablespoons of chia seeds, and up to 1/4 cup of pumpkin seeds. I do recommend adding some plant-based milk, about 1/4 cup to the mixture, though.
