Flourless Peanut Butter Banana Cake is fluffy and moist made with only 5 real ingredients and topped with a peanut butter frosting! You would never believe it’s healthy! Can be paleo and vegan too!
Hello Guys! I’m excited to share this recipe with you all today! This recipe (like others I’ve made) is born from past recipe creations morphed together.
As I was looking through my Pinterest board yesterday, I came across this Flourless Pumpkin Snack Cake. I remembered how amazing this recipe was (I mean, come on! You can’t go wrong with pumpkin cake with a chocolate frosting).
Then, I scrolled down to these Peanut Butter Banana French Toast Rollups and immediately had an epiphany. This was my discernment from God telling me to make a PB-Banana version of the flourless snack cake!
In my opinion, you can never go wrong with the peanut butter and banana combo, – it is always a winner year-round (for me at least). I think most people would agree with me, though I am probably slightly biased.
But, let me tell ya, this cake is oh-so-good. The base is adapted from the pumpkin version and it’s just so fluffy and moist, you would never be able to tell it’s flourless!
Additionally, this cake is suitable for dietary restrictions as well. It’s not only gluten-free but can also be vegan and paleo-friendly too! If you’re vegan, just sub a flax egg. Paleo? Sub in almond butter for the frosting.
Furthermore, this PB banana snack cake is so simple and easy to make too!

I seriously need this in my life, good thing I have lots of bananas
This looks HEAVENLY! <3
I love peanut butter and banana in an shape or form, however, especially when the peanut butter component is frosting 😉
As for flourless desserts – I think I'd have to go for a rich flourless chocolate cake. Yum!
We are both so on the banana cakes/breads right now!
Amazing!!! Nothing better than a peanut butter filled cake!!
Thank you! WE agree 🙂
Who doesn’t love all things banana cake/ bread!!!?
Thank you Kristy! all the peanut butter in banana things <3 and YES to flourless chocolate cake! MMMMMM!
It’s perfect for those extra ripe bananas! So yummy 🙂
My fave way to eat peanut butter and bananas? In baked treats just like this! Those are two of my favorite ingredients… so I’m seriously drooling over these!! 🙂
One bowl peanut butter banana bar……you can’t lose!
This sounds AMAZING. Ah I want to make this now with my bananas!!
Just yummy. Bookmarked it.
Hehe… I love how you compared this to bananas smothered with peanut butter, cause it looks just like that.
This looks delicious for breakfast. I usually do grsnola and fruit, but might have to try this instead. For the best granola recipes, check out my recent post at http://www.hopepostkids.com
Oh goodness these looks so good!! Thanks for naming it a “snack” cake… makes me feel like I don’t need to wait for a special occasion to enjoy!
Oh man! I love peanut butter and banana as a snack but this takes it to a whole new level!!
Such a gorgeous banana cake!! I am SO here with the Peanut Butter Frosting btw (HEART EYES!!)

HI Bethany & Rachel,
Just a note to let you know that I have chosen your post as one of features for this weeks Real Food Fridays blog hop that goes live a every Thursday @ 7pm EST. Thank you for sharing your valuable information and helping to make this world just a little bit healthier.
Oh I soooo need to make this! It’s Passover (aka The Gluten-Free Festival) as I’m writing this, so it’s perfect with the Paleo topping. I love flourless anything, but bananas are a special favourite.
Oh you so need to make this, you’ll love it!
Can I substitute sugar free pancake syrup or does it have to be pure maple? Thanks!
Do you have carb count on this?
We don’t, I’m sorry!
Just made the cake. Not as fluffy as the picture but very good. I used honey instead of syrup. Instead of frosting i will use a little butter or cream cheese to keep the carbs down but it’s actually moist enough it doesn’t need anything. A small piece will definitely satisfy my sweet craving. It’s a keeper!
Glad that you enjoyed it Rhonda! It’s one of our faves 🙂
This was delicious! I substituted honey for maple syrup seeing as I didn’t have any on hand. Found that my cake didn’t rise much in the center so instead of cutting into squares, I cut into 8 slices which I think actually looked even nicer! My peanut butter coconut mousse topping came out quite runny as I don’t own a mixer or whisk, so had to mix by hand with a spoon, but I improvised a bit and used it as somewhat of a sauce, with drizzles of salted caramel over top. Wish I’d taken a picture because it looked seriously lovely – had many people complimenting it for days afterwards! Thanks very much for a delightful recipe 🙂
Hi Katie,
We are so glad you made it and enjoyed it! If you happen to make it another time, tag us on instagram and we’ll share it on our story! 🙂
Yum! I cannot believe how good this turned out. I mixed up the batter in my food processor so it turned out very fluffy and cake-like. You would never guess there’s no flour in it. I watch my carbs so I subbed Swerve sweetener in both the batter and the frosting and it turned out wonderful.
So glad you enjoyed it Andrea!
Wow! This was delicious 😋 Thank you so much… this is the best cake I’ve had since going gf 1 year ago.
Thanks so much for making it! Glad you enjoyed it as much as we did 🙂
Perfect recipe! Easy and delicious! I used a food processor to mix all the ingredients and the cake came out nice and fluffy! It is very good without the “icing” but taking the extra time to make it definitely takes it to another level of awesomeness! Thanks for such a simple and delicious recipe!
So glad you like it Mel! 🙂
I made this recipe last week and it was actually amazing! My family and me couldnt believe that there was no flour! But I have a question, can I possibly make this in a 8 by 5 loaf pan and would it still come out as good? I just wonder because I kind of want to give off that banana bread instead of snack cake vibe.
Hi Emily,
So glad you enjoyed it! Yes it should still be fine in a loaf pan!
This recipe is amazing! I used Sunflower Seed Butter and Flax eggs! I cant believe how amazing this texture is! Thank you for this recipe!
Hi Justine,
So glad you enjoyed it! You are so welcome 🙂
Really enjoyed both the cake and the frosting. Especially the frosting. I used powdered sugar because I thought that it would give the best consistency. Thanks for the recipes!
We are so glad you enjoeyed it! Thank you for aking 🙂
