Peanut Butter Banana Bundt Cake

Jump to Recipe·Print Recipe

This Peanut Butter Banana Bundt Cake is like banana bread but lighter, filled with nutty peanut flavor and a salted caramel peanut butter glaze on top!

If chocolate found out this was happening, I’d be in trouble. Chocolate with banana – amazing. Chocolate with peanut butter – magical. But just this once let’s let banana and peanut butter collaborate on a cake without chocolate getting in the way.

Look, I love a good brownie as much as the next person. But even mini chocolate chips seem to steal the flavor show of whatever you bake them into. And with sweetness from extra ripe bananas, nuttiness from creamy peanut butter, and decadence from the salted caramel peanut glaze on top, we want to keep ALL the flavor for ourselves.

This recipe is like banana bread, but it is not banana bread. Because…

  • we are blending the bananas instead of mashing for a more consistent texture
  • the crumb is lighter and softer
  • the flavor is richer, more dessert than snack (but still can be both, of course!)
  • it’s baked in a bundt pan, not a loaf
  • SALTED. CARAMEL. GLAZE.

If you can’t tell I really love that glaze. Like really really really love.

But I have strong feelings for the cake too. The peanut butter flavor is not subtle…in a very good way. The bananas get even sweeter from baking, and combined with coconut sugar things quite caramel-y. And neither overpowers the other – they just harmonize perfectly!

If you want to add chocolate chips I won’t stop you (who would do such a thing?), but I urge you to try at least the first batch without. I think you’ll find banana and peanut butter to have some serious solo game of their own.

Description

This Peanut Butter Banana Bundt Cake is like banana bread but lighter, filled with nutty peanut flavor and a salted caramel peanut butter glaze on top!


Ingredients

Scale

Cake

  • 3 medium bananas (250g)*
  • 2 flax eggs (2 tbsp ground flax + 4 tbsp water)
  • 1/2 cup (70g) coconut sugar
  • 1/2 cup (125g) peanut butter
  • 1 cup (240g) nondairy milk
  • 2 cups (250g) oat flour
  • 1 1/2 cups (165g) almond flour
  • 1 tbsp baking powder
  • 1 tsp cinnamon
  • 1/2 tsp salt

Peanut Butter Glaze

  • 1/4 cup (60g) peanut butter
  • 1/4 cup (40g) maple syrup
  • 1/4 cup (50g) coconut oil, melted
  • 1/2 tsp salt
  • 1 tsp vanilla extract

Instructions

  1. Preheat the oven to 350ºF.
  2. Prepare flax eggs and set aside to gel for 5-10 minutes.
  3. Mash or blend the bananas.
  4. Mix together the banana, flax eggs, coconut sugar, peanut butter, and nondairy milk.
  5. In a separate bowl, combine the oat flour, almond flour, baking powder, cinnamon, and salt. Whisk to eliminate any clumps.
  6. Add the wet ingredients to the dry, and mix to form a batter. 
  7. Pour into a bundt pan** (mine was 10 cup but 8-cup would be fine too) that has been generously sprayed with nonstick spray.
  8. Bake for 40-45 minutes at 350ºF.
  9. Remove from the oven. Cool for 10 minutes. Flip onto a cooling rack to cool completely.
  10. Whisk together the glaze ingredients until smooth. If it’s too thick, microwave for 5-10 seconds.
  11. Spoon glaze onto cooled cake, and sprinkle with chopped roasted peanuts.
  12. Enjoy! Keep leftovers covered in the refrigerator for up to a week.

Notes

*About 1 cup after mashing. You can either mash with a fork, or blend to a puree if you don’t want any chunks.

**If you don’t have a bundt pan, cupcakes/muffins would be the best alternative. They will bake for slightly less time (about 30-35 minutes). You could try baking it in a regular cake pan, but I don’t recommend a loaf pan for this recipe.

    This is beautiful and delicious! I’m usually someone who would incorporate chocolate, too, but I decided to just let the peanut butter and bananas shine. I omitted the sugar in the cake, and I thought it was sweet enough with super-ripe bananas, but I hardly ever eat sugar. For the glaze, I just combined date syrup, peanut butter, and vanilla. Just trying to limit sugar and oil over here, and I’m only mentioning it in case anyone else wants to do the same, but I’m sure your original version is delicious! And the texture… awesome!

        Bundt pans are typically measured in volume not dimensions, but my 10 cup bundt pan is approximately 9″ in diameter (https://www.nordicware.com/bakeware/classic-sized-bundts/elegant-party-bundt-1). And that will get you about 12 slices!

    Natalie, this cake is so beautiful!! Like, I can’t even believe how gorgeous it is. I love the peanut butter glaze so much. I’m pretty sure I would drink that if I had the chance, lol. I mean, for real. And I’m such a lover of peanut butter, but I don’t have it very often since my family can’t eat it. I’m totally with you on the chocolate chips stealing the show, too. Seriously, they are always like “hey it’s alll about me” whatever they are baked into, right? Haha! Such a gorgeous cake that I keep looking at and that shot of the spoon drizzling the glaze over is one of the prettiest shots you’ve ever taken it. I’m thinking of blowing it up and hanging it on my wall!! Great recipe Natalie!

      I can eat peanut butter (and live alone lol) but for some reason I’ve been seriously neglecting it lately too. I guess my SunButter obsession is to blame, but sometimes gotta give good ol’ PB some attention😊 Bahahaha you chocolate chip impression is so right though, especially when they melt and just ooze into every bite…delicious little attention seekers😂😂 Lol always love a good bundt cake drizzle shot, something about a bundt cake just calls for a glaze to me🤷🏻‍♀️ Thanks for the kind words, Brandi!

    Could I use all purpose flour for this and also ordinary sugar instead of coconut sugar. I bought a bundt pan a while ago and I think this might just be the right recipe for it!

    Reply
    • Natalie says

      March 19, 2019 at 6:07 pm

      Yes and yes! Although both may make it a little more dry because AP flour is lower fat than almond flour, and white sugar contains less moisture than coconut as well (brown sugar would be better!)

    Reply
    • Natalie says

      March 22, 2019 at 5:26 pm

      Just almond flour will make it to moist/mushy and it won’t cook though properly. I’d try using a pre-mixed paleo flour mix (I like this one from Bob’s Red Mill: https://www.bobsredmill.com/shop/paleo-friendly/paleo-baking-flour.html) in place of all of the flour, but the texture will still be different. Good luck!

    Hey!! I can’t wait to make this recipe! Why do you suggest not using a loaf pan?!

    Reply
    • Natalie says

      March 24, 2019 at 11:03 am

      Loaf pan’s are very deep compared to a cake pan so it’s hard to get the center to cook through properly without the outsides getting overdone. Bundt pans are awesome because the hole in the center makes for more even heat all around and no risk of a mushy middle that will fall when you take it out of the oven. In general loaf cakes are tricky (especially without eggs/gluten!) so a cake or bundt pan is really best here, if you were to use a loaf you’d need to bake it for a lot longer and even then the center might not be completely done. Hope that makes sense 🙂

      What size/shape pan did you use? The peanut butter and almond flour should be enough to keep it moist, so sounds like you just need to bake it for less time😊

      You can try only oat flour, but it will make the texture quite dense/gummy so I don’t recommend it. Can you find any nut flours there? If not, you could grind your own almond flour in a blender!

    I made the cake and it came out thick and gummy. I thought maybe I left out the almond flour so I made it again a second time and it came out the same way. I was so looking forward to the fluffy nice texture in the picture and not even close. I followed the recipe exactly as it was written and it didn’t come out anywhere close to the pictures. So disappointing!!

    I made this cake yesterday for a potluck and it turned out great! Everyone enjoyed it very much. Thank you for adding the weights of the ingredients, I prefer to bake that way. I did put mini chocolate chips in half the batter and cut half the sugar as another baker suggested. It was not very sweet, which I prefer. If you like it sweet, then I would suggest to keep all the sugar. My glaze did not turn out quite as nice as yours though. Of course, the consistency of the peanut butter being used can easily change the glaze. As I was making it, my gut feeling was to cut back on the coconut oil, and I should have listened because it was pretty thin and too oily for my liking, But once it put it on the cake, no one noticed. Thanks again for another great recipe!

        Do you think I could sub almond for coconut flour? Both are fine and fat. Almond is quite expensive. I tried the recipe using only oat flour just to see how it would turn out. I had to add at least 3/4cup more milk. Result? Gummy but edible.

          Hi Raquel! Coconut flour will not work here unfortunately😔 Yes coconut itself is high in fat like almond flour, but actually most of that fat is removed when they make it into flour so it’s very dry and will make this cake really crumbly and dry too. Your best bet would be to go with a gluten-free or all purpose blend instead of both of the flours, reducing the totals amount by 1/2-3/4 cup. But again I haven’t tested that so I can’t say for sure how it will come out.

    Hi Natalie, I can’t wait to try this recipe. I was wondering, when converting SAD “baked goods” recipes. Do you know how much difference Flax Eggs VS Chicken Eggs make. Can you always sub flax eggs and get pretty good results? I realize you couldn’t sub flax eggs in eggs heavy cakes like angelfood cake or chiffon cake. But, for things like muffins, quickbreads and cakes calling for one or two eggs can most of them just be converted using flax, or “egg replacer”? I would really appreciate your opinion on this, since I am just starting to try to convert recipes myself rather then following vegan and WFPB recipes. Thank you! Mary Beth.

      Flax eggs generally work pretty well as a one for one swap with chicken’s eggs, although they will never give the same amount of rise as real eggs. They do replicate the binding abilities of normal eggs quite well, but that fluff is never quite the same (and honestly I haven’t found a vegan sub that does give quite that same fluffy texture). The other alternative I use and like for eggs is tapioca starch, not sure if you’ve tried that one yet! Hope that helps😊

    This was my first ever bundt cake and I am thrilled with how it turned out! I just received a beautiful bundt pan for my birthday so I scoured the internet for a nutritious bundt cake recipe to make for brunch. I love baking with almond flour & oat flour so I knew I had to try this. The peanut butter and banana really do shine without chocolate chips (which I normally ALWAYS include in banana bread) and the salted maple glaze takes it to a whole other level of deliciousness. I can’t wait to try the other bundt cake recipes on this site.
