Moist and dense banana cake is filled and frosted with peanut butter buttercream and decorated with whipped chocolate ganache making this Peanut Butter Banana Cake with Whipped Ganache a seriously delicious indulgence.
If you haven’t noticed I’ve really gotten into cake decorating lately. I think it is actually one of my hidden passions that I’ve really gotten into the past year. Actually it spans longer than this past year, but I’ve really tapped into some fun flavors recently.
I’ve been making specialty decorated cakes for my kids birthdays for many years now, but that’s about as far as my decorating experience has gone. But I am seriously addicted to cake so I figured I’d give it more of a go and play around with some fun stuff and I’ve been happy with some of the results!
If you haven’t caught some of my cakes in the past, you can find a variety of flavors if you just search cake. Or you can find Pumpkin Spice, Chocolate Raspberry and Lemon Poppyseed if you want a fast way to find them, just click on the names where they appear a different color.
Ok, so cake. Literally I can live off of cake. My husband is not the sweets type as I’ve highly said in my previous dessert posts, which leave me to eat all this cake I’ve become addicted to. Luckily I have some willing people in my life that are glad to take extras off my hands when need by…because even as much as I love cake, I feel bad eating the whole thing by myself. And obviously I don’t want it to go to waste.
My newest creation is this Peanut Butter Banana Cake with Whipped Ganache! You guy’s, I’ve never loved peanut butter and banana together more than I do in this cake. Like for real. Can I tell you a little secret? I don’t think I’ve actually had banana and peanut butter together before I tried this.
Yup, that’s right. I was a newb to these flavors. Thanks to some insisting by another blogging friend of mine, I decided to go for it. And it is heaven. Seriously, if you’ve never tried these flavors together before, I URGE you to. Making this cake would be a good start!
This cake is a perfect dense cake for my liking, so it holds together really well. And if you never knew it before…you can make whipped chocolate ganache. That’s right! It’s not just for pouring and dipping anymore. Whip that baby with your hand or stand mixture and you have a light and fluffy indulgent frosting.
The texture of the whipped ganache alone makes me swoon. It’s kind of like a mixture between a buttercream and a mousse. It’s light and fluffy, but still packs a flavor punch. I always make my ganache with semi-sweet chocolate, but if that’s too strong for your liking, it’s really easy to add a little bit of flavoring to it to tone it down.
I seriously love this cake though. This might just be overall one of my favorite flavors that I have made. But I’m sure I’ve said that with all of them!! It’s so hard for me to not like a cake. Ok…well not too hard, one cake that I can’t stand is Angel Food Cake. Yeah, I know it’s weird, but I think it might be a texture thing for me. It’s TOO light and fluffy for my taste.
I really enjoy a dense cake here and there, or a crumby one. But I usually aim for something in the middle. Oh and they have to be moist. That is key for my fave cakes, that way they stay together well. A little trick I use when I get a more light cake is to add a little simple syrup between my layers before I add the filling. Makes it stay moist and doesn’t dry it out.
With this Peanut Butter Banana Cake I didn’t do that, it had just the right moistness to it that it that all I really needed to do is frost it and devour, and that’s exactly what I did. I devoured this heavenly treat and I can’t wait to try this one again!

That is awesome Ken!! That made my day, I’m so happy it worked out for you. I hope everyone loves it!
Hello I made this and am about to put it together. Your recipe says 1 bag of chocolate chips but since they come in all sizes I was wondering if it was the 12 oz or 24 oz size? Thank you!
Hi Ken, I apologize for not clarifying but it’s a 12oz bag! Hope that helps.
Nothing goes better together than peanut butter and bananas, well maybe peanut butter and chocolate, but you’ve got all of those bases covered. Thank you for sharing at the Creative Muster Party. PINNED!
I agree, these flavors totally meshed well!
I’ve never even considered whipping ganache! You’re brilliant! Thanks for sharing.
Thanks so much Robin!! The texture is so light and amazing but still has all the flavor of normal ganache!
In the ingredients list, it calls for 1 container of peanut butter. I don’t know how it is where you live. But here where I live in Canada we have several sizes of peanut butter. So I’d like to know what size of jar did you use for this recipe?
Hi Susan, thanks for your question. I finally got around to editing that in the recipe. It is a 16-18oz (depending on brand) container! Hope that helps you 🙂
sounds yummy but I’m curious as to how much is a container of peanut butter?
Thanks Therese! And thank you for pointing that out. It’s a 16oz container of peanut butter.
