Peanut Butter Banana Muffins – gluten, grain, dairy and sugar-free

Peanut Butter Banana Muffins - gluten, grain, dairy and sugar-freeBarry Goldwater Quote
This is the simplest recipe ever. It was given to me by my niece – thank you, Kirsty. It has a minimum of ingredients and no flour or sugar at all. And yet they turned out looking and tasting just like muffins should. Who would have thought it! I love making elaborate slices and tarts but sometimes a batch of quick muffins is just what’s needed. I made some marshmallow, caramel, chocolate bars for a guest post last weekend and Adriano didn’t like them. He prefers the simplicity of muffins or a piece of cake. I, on the other hand, loved the bars.

  1. What a simple recipe. We are all in Kirsty’s debt.

    I’m trying to imagine shaving my underarms with peanut butter. All I’ve got is extra crunchy :)

  2. I’ve been trying to imagine it myself. The crunchy would certainly be an interesting experience but the blade might get upset.

  3. Mmmmm…..these sound so tasty, and love that they’re so darn simple! What a yummy way to start the day.

  4. I love Maureen’s extra crunchy remark! And these muffins look great, too. Nice, easy recipe. Congrats on the next 2 books. ;-)

  5. These look amazing! I love the peanut butter and blue berry combination.

  6. I love peanut butter, what tasty muffins!

  7. You got me with words “This is the simplest recipe ever”, hahahha. It also looks delicious. I’ll make my peanut butter especially for this recipe.

  8. Oh my ~ This one’s right up my alley :-)

  9. I knew there were a lot of uses for peanut butter but shaving cream? That’s a new one. I love the look of these muffins and yes, they look like the ‘real’ thing despite the fact there’s no sugar or flour. Who’d have thought! xx

  10. Hi,love this idea. Would it work with cider vinegar and replace blueberries with apple bits perhaps? Some vinegars aren’t gluten free. Thanks.

  11. So you’re an amazing cook and photographer, AND you’re a published novelist?! Is there anything you can’t do?! ;)

    I love how simple this recipe is!

  12. I love it when a simple recipe works so well! And, I have lots of blueberries to use right now. Just in time.

  13. I substituted the egg with chia seed meal + water, and while the taste is great, I had to bake them for thirty minutes. They do taste great. Oh, and I topped them with chocolate chunks instead of adding blueberries :)

  14. Mine are still peanut butter consistency after 20 min. Any suggestions of what I should do differently next time? Thanks!

    • I’m not sure, Emily. I have made them several times now and they have always worked. Maybe it’s something to do with the size of the eggs and the size and ripeness of the bananas – but really not sure since it has not happened to me.

  15. Hi. What type of vinegar do you use? Eg red or white wine vinegar? Thanks

    I’m really excited to make these. It’s so nice to see such a simple recipe. However, I’m thinking of exchanging the peanut butter for sunflower seed, and perhaps do chocolate instead of blueberries, ( it’s for a kid birthday party).

    Can I sub like for like? Or do you think it may be tricky?
