And there is absolutely NO FLOUR in this recipe, of any sort! Not even oats!

From Janet Thomas: “I made this, it was easy to throw together, tasted great and stayed moist for days. Thankfully everyone else in the house dismissed it without trying it, they assumed it was going to be a healthy and bland concoction, so I had it all to myself and it was as good when I finished it four days later as it was the day I baked it. Great recipe”

Ingredients and Substitutes

Ripe bananas, mashed (3) – Spotty bananas work best since they are sweeter. You can also use apple sauce.

Drippy peanut butter (1 cup) – If peanut butter isn’t your thing, you can use almond butter or sunflower butter.

Eggs (2) – You’ll need to use eggs here.

Baking powder (1 tsp)

Walnuts or pecans, chopped (1/4 cup) – Swap with sunflower seeds or chia seeds.

Dark chocolate, chopped (2 oz) – Try using cacao nibs for extra crunch and flavor.

Step 7. Sprinkle the chocolate chips on top of the batter.

Step 8. Place in the oven and bake for 50-55 minutes. Once it cooks, let it cool down before slicing and serving. If you notice that the top of the bread is browning very quickly, cover it with foil to prevent it from burning. Check whether you need to cover it with foil after around 20 minutes.

My Storage Tips

Place any leftovers you have in an airtight container at room temperature for up to 3-4 days. If you want to keep it for longer, place it in the fridge for 4-5 days.

To keep it for longer, slice your loaf and freeze it in individual portions. Wrap each slice in plastic wrap and store it in a freezer-safe container.

Keep in the freezer for up to 2 months. When you want to have it again, reheat it in a toaster or microwave.

  1. Pat says:

    What size is the loaf tin? 8×4 or 9×5?

    1. Karolina Miles says:

      I used 4×9 in this example. I’d go with 8×4, the slices will be a bit bigger.

  2. L. says:

    What if I don’t like peanut butter, can I just leave it out, or do I need to substitute something else for the consistency to turn out right?

    1. Karolina Miles says:

      You still need the nut butter; the recipe won’t work. I would do almond butter.

  3. F. Cleary says:

    I had to give this recipe 5 stars, even though it fell while cooling! Probably need to cook it a little longer next time. (I microwaved each piece to cook it a little more.)
    The flavor is WONDERFUL, and itโ€™s very filling and satisfying!

  4. Penny says:

    What size banana

    1. Karolina Miles says:

      Medium to large. ๐Ÿ™‚

  5. Anam says:

    Can we make it without peanut butter or what is replacement?

    1. Karolina Miles says:

      You can use almond butter. The nut butter is essential to this recipe to keep the bread structurally intact despite it not having any flour.

  6. Mandy says:

    I love banana bread. This was the perfect recipe for flour free baking (an ACTUAL flour free recipe!) Not like others that just replaces regular flour with another type of flour or oats!

    It was soft and sweet (without adding sweetness!) and so very tasty.

    I was VERY pleasantly surprised how well it came out. This recipe will now be a staple.

    Love this recipe. I have made it twice and will continue to make it. Added 1/2 tsp of cinnamon and vanilla, just to try something different. I liked it a lot with and without the added ingredients.

    1. Karolina Miles says:

      So glad to hear it, Kenny! Thank you for the little review!
