Caramelised Banana, Coconut, Chocolate & Peanut Butter Cake

Did you know it is World Baking Day on Sunday 20th May? Sponsored by Stork, 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. Ideally, photograph your cake “somewhere interesting” in an unusual place or setting, then share the photographs via Twitter using the hashtag #caking or go direct to the World Baking Day website. Stuck for ideas? You will find plenty on my blog or again you could take a look at the World Baking Day site.

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, Stork margarine 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.

So what to make was the big question? Well it didn’t take me too long to figure 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 was going to make a banana cake with chocolate chips sandwiched together with peanut butter icing. 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 was a revelation and 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. The icing I based loosely on a recipe by Eric Lanlard in Cox Cookies & Cake.

This is what I did it:

  • Poured 150g caster sugar and 50ml of water into a heavy bottomed pan and placed on a low heat until the sugar was melted.
  • Brought the mixture to a boil, until it turned into a light brown caramel.
  • Added 4 chopped bananas and turned down the heat to a simmer.
  • Added 40g unsalted butter and let the mixture simmer for about 5 minutes until the bananas were mushy.
  • Added 50g desiccated coconut & 2 tsp vanilla extract. Stirred and left to cool.
  • Creamed 175g Stork margarine (I’d normally use butter, but as this was sent to me, I thought I’d try it out).
  • Added 120g light brown sugar and creamed until pale and fluffy.
  • Beat in a goose egg (4 medium hens eggs).
  • Beat in the banana mixture.
  • Stirred in 1 tbsp yogurt.
  • Sieved in 200g self-raising flour, 60g rye flour, 1/2 tsp baking powder and 1 tsp bicarb of soda and folded until just combined.
  • Gently stirred in 50g of chopped dark 70% chocolate (G&B).
  • Divided mixture between two 22 cm cake moulds and baked at 180C for 30 minutes.
  • Left to cool for 15 minutes then turned out onto wire racks to cool completely.
  • Creamed 50g unsalted butter.
  • Added 150g smooth peanut butter & creamed some more.
  • Sifted in 200g icing sugar and creamed until pale.
  • Added 4 tbsp whipping cream and 1 tsp vanilla extract & beat until light and smooth.
  • Sandwiched the two cakes together with half of the mixture and spread the other half on top.
  • Decorated with various chocolate sprinkles.

I can only describe the result as being the Rolls Royce of Banana cakes. It had a good crumb structure and was really light – so light in fact, as CT stated, that you could have a really big slice and not feel full. The taste was fairly sublime too and neither of us are ordinarily big fans of banana cake. 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 balanced out really well with the sweet, salt and bitter each playing their part. The individual flavours of banana, peanut, coconut and chocolate could be tasted separately, but also formed a sublime whole. As Alexander Dumas would have put it: “All for one and one for all”.

So get your pinnies on ready for Sunday and join in the fun.

    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
