Caramelised Banana Cake with Peanut Butter Icing

Caramelised banana cake filled and topped with peanut butter icing.

The Rolls Royce of banana cakes. This caramelised banana cake is sandwiched and topped with creamy peanut butter icing, then sprinkled with chocolate chips. The cake itself is made with caramelised bananas, coconut and chocolate chips. It’s lush.

Did you know it is World Baking Day on the third Sunday in May? The idea is to have some fun baking a cake and then sharing it with others, whether that’s in actuality or sharing a picture. This year the theme is to photograph your cake “somewhere interesting” in an unusual place or setting.

You can see from the above photo that my bake was undercover in the undergrowth.

If you’re stuck for ideas as to what to make, you’ll find plenty of recipes in my baking section.

I was lucky to be given some encouragement by the organisers in the form of an an amazing box of goodies to use in the making of my cake. This not only included flour, baking powder, sugar, cocoa and various cake decorations, but also a splendid silicone spatula which has a built in rest to keep the blade off the work surface and a very handy recipe journal.

Caramelised Banana Cake with Peanut Butter Icing

So what to make was the big question? Well it didn’t take me too long to figure it out. Last week I couldn’t resist buying up a load of bananas I saw going cheap. Then, serendipitously, the very same day I saw the most amazing banana, chocolate, peanut butter layer cake on Buttaz Blog.

Although I wasn’t quite ready to make anything as grand as that, it did form the inspiration for the flavours I wanted to use. I would make a banana cake with chocolate chips sandwiched together with peanut butter icing. But not just any banana cake. Oh no.

Peanut Butter Icing scattered with dark, milk and white chocolate chips.

At Christmas last year I’d made Dan Lepard’s Butterscotch Banana Cake, in muffin format for the guys next door, using that most excellent of books Short & Sweet. Well caramelising the bananas is a revelation. It transforms a simple banana cake into something else entirely. Inspired by this, I upped the quantities, omitted the spices and nuts, added coconut and then some chocolate, of course. Then I filled and iced it with a creamy peanut butter icing.

This is one highly calorific banana cake, so it’s best reserved for birthdays and other special occasions. But sometimes calories just shouldn’t come into the equation.

I can only describe the result of this caramelised banana cake as being the Rolls Royce of banana cakes. It has a good crumb structure and is really light. So light in fact that you can have a really big slice and not feel full, said CT as he tucked into his second slice. The taste is just sublime. The peanut butter icing I could have happily polished off with a spoon before ever it got to the cake, but I held fast. 

The flavours balance out really well with the sweet, salt and bitter each playing their part. You can taste the individual flavours of banana, peanut, coconut and chocolate separately, but they also form a sublime whole. As Alexander Dumas would have put it: “All for one and one for all”.

    That cake looks amazing. I think the banana and peanut butter would be a real hit in terms of flavour combinations. I have never caramelised bananas before adding to a cake either, but what a fan idea.

    This cake looks wonderful. Wish someone would leave me a slice on my doorstep !!
    I am not a fan of peanut butter but for some reason, goodness knows why, I have a jar of the smooth version in the cupboard……..

    I looked at the World Baking Day website and some of those pictures are very witty. Great fun. Now I have worked out that tweeting is not essential to taking part I might just have a go…..excuse for baking number 38c !!

    I am loving the way you caramelised the bananas in caramel and can imagine this turned a good banana cake into something very special indeed. It is something I would love to try especially with that icing. What a good idea as always!
    I am out all day tomorrow and have been gardening all day today so sadly I will not get to post anything for World Baking Day. Also, intending to write up my We Should Cocoa post tomorrow evening and that takes precedence for me!
    Happy Baking Day 🙂

    yay… that last photo of the cake on the doorstep is genius and really made me smile… I love it… I love the fact that it is going to make me check to see if you drove over from home to deliver one to my front door… but also makes me smile because i’m the kind of person not to notice and step right in it… which is why it is so genius… as well as the fact that the cake looks superb! x
