  1. Heat oven to 160C/140C fan/gas 3. Grease and line a 2lb loaf tin with baking parchment (allow it to come 2cm above top of tin). Mix the sugar, flour, bicarb, cocoa and chocolate in a large bowl.

  2. Mash the bananas in a bowl and stir in the whole egg plus 2 yolks, followed by the oil and milk. Beat the egg whites until stiff. Quickly stir the wet banana mixture into the dry ingredients, stir in a quarter of the egg whites to loosen the mixture, then gently fold in the rest. Gently scrape into the tin and bake for 1 hr 10-15 mins, or until a skewer inserted comes out clean.

  3. Cool in the tin on a wire rack. To make the icing, melt the chocolate and soured cream together in a heatproof bowl over a pan of barely simmering water. Chill in the fridge until spreadable. Remove cake from tin, roughly swirl icing over and scatter with the banana chips.

Easy, tasty recipe. Used roughly 200g bananas andgot good flavours coming through with the choc. Thought about putting the icing on, but half the cake disappeared almost as soon as it came out of the oven, so maybe next time!

This recipe makes a wonderful moist chocolate cake with or without the topping - I have made it a few times now and use Ground nut oil as I always have it in my cupboard , two Bananas and split the mixture between two fluted Victoria sandwich tins and Hey Presto a very impressive looking chocolate cake! Didn't like the sour cream topping , have tried low fat cream fraiche which is better and not too sweet and served it this way as a dinner party desert and also chocolate buttercream for childs Birthday cake -both were great successes.

Ive made this about 4 times now and it always goes down well with everyone. I add more chocolate chunks than it says and I sometimes put fudge chunks in aswell just to make it taste a bit different

My 8 year old son loves to cook and bake so we decided to make this cake following the exact recipe.
I was delicious and turned out perfect - very pleased with the results.

Just made this & its a total disaster!!!! The middle has not rised & it's uncooked - any ideas what went wrong??

Yum! Easy cake to make and looked good without the topping but I piled that on as well - really nice and only need a little slice for a lovely treat. Going to try cupcakes as well!

This went down really well! Instead of the dried banana on the topping I cut the cake into three layers and had a layer of whipped cream and a layer of the (sour cream + choc). The whole cake went in under 6 hours :)

I added extra banana due to the comments on here and it didn't hamper the recipe at all, I think it was 3 medium size ripe ones in the end. I also baked it in 2 x round cake tins and layered it with icing (of which I cheated and bought ready made) to make it as a birthday cake and this reduced the cooking time to just 40 min.

It was a real hit with everyone, lots of compliments!

I have made this receipe several times & it's great. I make it with vegetable oil and I don't bother with the icing as it is so sweet and moist as it is. It freezes really well.

this was very easy, tasted lovely and the best thing is i can freeze some of it, so on my diet i dont feel the need to eat all of it.

Really rich and chocolately, but I could still taste the banana. I like the idea that vegetable fat is used rather than animal fat, although calories are calories I suppose! The oil and banana keeps the cake lovely and moist too. I used good quality dark choc for the topping, which ended up quite bitter with the sour cream. Although tasty, I think a slightly sweeter chocolate would be better.

OMG this was delicious and so easy to stayed really moist for a couple of days - although it was hard making it last that long as I just wanted to eat slice after slice....will make again....and again!

This is absolutely delicious and loved by all the family. It is easy to make especially when you are assisted by a 3 year old grandchild!

Great cake! I have frozen it in slices (without the topping) so hope they work out ok defrosted!

Excellent cake! Made this on Saturday and it was gorgeous. Didn't have soured cream in my local Aldi so used reduced fat creme fraiche instead and it worked just fine so will do the same next time I make the cake.

For the topping I used half sour cream and half 0% fat greek yogurt for a lower fat version. For those that complained abut the topping being too runny I added the cream mixture to the melted chocolate rather than melting both as it says in the recipe. Then I put it in the fridge for an hour to cool. It was lovely and thick and spread easily. The cake rose well and was reasonably moist. I don't know how well it keeps because it stick around long. Family comments were a nice chocolate cake without being over banana-y even though I used abut 200g of bananas.

i was fed up throwing over ripe bananas out so looked for something to use them up. This is a great recipe. My son is dairy allergic so i did not top it but still a big hit.My ten year old daughter who does not like bananas wants this for her birthday cake. A new family fav

I made this and like other people didn't realy taste the banana, I'll use more next time
It stayed lovey and moist
The sour cream topping was different, I had to keep eating it to see if I really did like!

I used rapeseed oil. Didn't do the topping, but rose really nicely and has a lovely flavour.

This rocks...i used veg oil and cooked for about an hour though could have prob done with less time. Missed out the banana chips as they are pretty ming and put frosting in the middle. Def going to try this again.
