PB2 banana bread 4

Did someone say low fat peanut butter and chocolate banana bread!  What a mouthful, literally.  This peanut butter and chocolate banana bread is seriously mouthwatering, moist and (most importantly) healthy.  For any traditional banana bread fans you will want to know about this one.  While it’s not ‘traditional’, it has some pretty mega health benefits in comparison to traditional banana bread.

What are the health benefits, you ask (and if you didn’t ask, I’ll tell you anyway).  This low fat peanut butter and chocolate banana bread is:

  1. Naturally sweetened with fruit, not processed or refined sugar;
  2. Naturally low fat, no added butter, oil or fat;
  3. Made with only five ingredients;
  4. Dairy free, making it easier to digest;
  5. Vegan if you swap the egg for chia seeds and water.

This recipe uses chocolate PB2, a low fat peanut butter powder that turns into a peanut butter paste once hydrated with water.  It has 85% less fat calories than traditional peanut butter.  While I am not a huge fan of peanut butter, if I do want to use it I opt for PB2.  By adding chocolate PB2 to this recipe, the banana bread has a delicious hint of chocolate and peanut butter.  YUM!

As an added bonus, my toddler LOVES it!  A perfect alternative to muffins, cakes or biscuits.

***EDITED NOTE: I’ve had a few questions and comments about cooking times.  Ensure you pre-heat your oven so that it is hot when the loaf goes in.  Also, you will see from my photos that I have used a LONG loaf tin that is quite shallow.  If you are using a smaller tin you may need to adjust the cooking times.  Continue to bake in the oven until the loaf is cooked through.

The loaf is moist and a knife will not come out clean (as per the photo above), but the loaf should still be cooked through.  If you have any issues please leave a comment below or email me at prettyweethings@gmail.com xxx

***To mill oats into flour, simply add oats to a food processor and blend into a fine consistency.

    In this recipe, when you say 1/4 cup PB2 – is that 1/4 cup power or reconstituted? I’m thinking reconstituted but want to make sure! Want to make asap!!

    I was sooo hoping these were going to turn out! Maybe it was supposed to be hotter than 180 degrees?? Turned out a bit mushy…maybe my bananas were too ripe. Looking forward to trying other recipes 🙂

    1. Oh no! Was your oven fan-forced and did you pre-heat? It may also be the depth of your pan. If you find it hasn’t quite cooked through then leave it in for a further 5-15 minutes. The slice is moist but should still be cooked through as per the photos!

    Are you sure it’s supposed to be 180 degrees F? I have a really hard time believing this will cook in the time allotted. Just wondering if you’ve tried to raise the temp? Or if I was missing something 😉
