Peanut Butter Banana Bread

What did people do with over ripe bananas before banana bread was invented? I always used to make mine with walnuts and chocolate chips. Classic. Delicious. Then a little over a year ago I developed an allergy to walnuts, which means my classic banana bread recipe will make my face swell up into something that looks like this:

I haven’t made banana bread since.

So I need a new banana bread recipe. I could put just chocolate chips, but that seemed too easy. After a quick consultation with Janice, I decided peanuts was the way to go. Unfortunately I forgot to buy the peanuts. Instead I used peanut butter, sort of like a pre-made peanut butter and banana sandwich.

My results were mixed. The flavour was great but the overall experience was lacking. I wanted the peanut butter to swirl through the batter, but the two ended up almost completely combined. I think because of the that the cake was a little dry, sort of like having peanut butter without a glass of milk. I also missed the texture of the nuts in the banana bread. Next time I’ll remember to buy the peanuts.

I’m posting the recipe as I made it, but I’d suggest increasing the amount of mashed banana or yogurt, or maybe even butter. Some experimenting may be required. Or just a large glass of milk.

Peanut Butter Banana Bread

  • 2 cups all-purpose flour
  • 1/2 cup sugar
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 3 ripe bananas, mashed
  • 1/2 cup butter, melted and cooled
  • 2 eggs, lightly beaten
  • 1/3 cup plain yogurt
  • 1/2 cup peanut butter
  1. Preheat the oven to 350 degrees.
  2. Whisk flour, sugar, baking soda and salt together in a large bowl.
  3. In a separate bowl combine the bananas, butter, eggs and yogurt.
  4. Create a well in the dry ingredients and pour the wet into it. Using a rubber spatula, fold the dry ingredients into the wet until just incorporated.
  5. Pour the batter into a greased 8 by 8 inch pan. Dollop the peanut butter randomly over the batter and swirl into the batter using a knife.
  6. Bake for 30 to 35 minutes, until a tester comes out clean.
  7. Let cool before serving.


PS: If anyone has a fail proof swirling method, I’d love to know what it is!

  1. You just in the past year developed an allergy to walnuts? I think that’s the strangest thing, for people to develop allergies after they are all grown up.
    Anyways, this bread looks great. Maybe it would seem less dry if you dipped it in milk, like a cookie? Who knows, stranger things have happened ;] Next time you should swirl some jam in there too!

  2. Looks really good!
    Maybe you needed to mix the pb with eggs/sugar to make a batter to swirl through, rather than just the pb which might just melt into the bread? Just a thought…

  3. I do think you were on to something….it sounds like a flavor sensation, and I like the idea of the peanut butter swirling thru the cake….hmmm
    have to think about it!

  4. I’ve made peanut butter banana muffins, but I would have never thought to actually try adding peanuts.. what about pecans? I bet that would be good too if you have to make it without walnuts. It sure does look yummy!

  5. I make something very similar, Peanut Butter Banana Chocolate Chip Muffins… one of our neighborhood favorites. We use baking powder, more peanut butter, brown sugar in addition to the white and no butter. Pretty close though! Love your pic!

  6. great combo of flavors.
    Yes it is possible to develop (and be freed from) various allergies throughout one’s lifetime!

    I’d be interested to see if combing the PB with egg mixture helps with the swirl effect.

    Another thought I had was to combine the PB with some peanut flour to make it thicker and less moist. Kind of the way a coffee cake has that cinnamon swirl thing going on — it’s kind of dry and crumbly. It might be nice to add some brown sugar also in the PB mix and maybe some chopped peanuts. I think that way, the peanut flavor would stay separate from the banana cake part… I’m totally in love with peanut flour and just did a post on its versatility…

    Please let me know how it goes if you try it!

  7. Ooh, that is SO interesting! A combination so simple and every day, yet I would never have thought to put it together in banana bread- but why not?! Thanks for the great idea!!!

  8. One of my favorite flavour combos….I think I would try making a peanut butter icing instead, and just stick with adding the actual peanuts to the bread. Would make it more dessert-like, which might be just fine. :)

    Great site by the way!
