  • 50g marshmallow, chopped, plus extra whole ones to decorate
  • 450g jar dulce de leche


  1. Heat oven to 190C/170C fan/gas 5. Grease and line the bottom of a round 21cm loose-bottomed cake tin. With a wooden spoon or electric mixer, beat the butter and sugar together until smooth and a pale, creamy colour. In a separate bowl, sift together the flour, baking powder and cinnamon. One at a time, beat each egg into the butter mixture along with a tbsp of the dry mixture, then beat in the milk and fold in the rest of the dry ingredients until well combined.

  2. In the bowl that contained the flour, mash the bananas until smooth and lump-free – whizz with the electric mixer if needed – then fold into the rest of the mixture until well combined. Spoon into the tin and smooth over the surface. Bake for 45-50 mins, until a skewer inserted into the centre comes out clean. Leave to cool for 5 mins, then remove from tin and continue cooling on a wire rack.

  3. Use a serrated knife to cut the cake horizontally into 3 equal layers. Whip the cream until it forms stiff peaks, then chop the banana into small pieces and fold into the cream, along with the marshmallows. On the first layer, spread a generous covering of the dulche de leche, followed by half of the cream mixture. Sandwich the second layer on top and repeat. Thickly spread dulche de leche over the top of the cake, then arrange extra marshmallows around the edge.

Made it for my son's birthday. Looked very nice with candles on, but the taste was too sweet. Good for the very sweet-toothed, but a bit over the top for us.

Great cake, dosent last long though because its fresh cream so better for parties that at home eating, as its very rich, you can only have a small slice. Everyone has loved it, especially the kids, im doing it again on sunday for my sons 2nd birthday party!

This cake rose beautifully and (suprisingly) I cut it into three parts really well. I then dropped it and had to piece it together with the cream and Dulce de Leche filling. Despite the disaster it went down a storm and never have I seen so much cake eaten by so few!!

Tasted okay. Though the sponge wasn't as moist or as tasty as I'd hoped.

This is lovely and easy to make, i didnt make 3 layers i done 2 layers and made a little one on the side ( a taster). SO didnt use all the cream. I feel majorly fat after one slice lol but worth it. Im keeping the big one for tomorrow, little sisters 10 bday.

It wasn't as pretty as the picture above, but nobody cared, it was delicious. The cake itself is lovely even without sticky toffee gooey stuff, but we liked it with, although my daughter very helpfully pointed out how many calories and how much fat and sugar there was, but at the time I didn't care :)

I made this cake for a party. I followed the recipe to the letter. However, the cake didn't rise as much as I would have hoped. It did rise enough to fill it with one layer of caramel (the Carnation caramel bought from Asda), cream, banana and marshmallows and tasted delicious. I have already had requests for two more!

Wretched thing didn't rise so was unable fill it. However, I put Caramel (the Banoffe caramel made by...begins with a C...Carnation??) on the top, then topped it with the cream, marshmallows and bananas.

was disapointed it didn't rise much but tasty (and SO rich) nevertheless!

You can find Dulche de Leche in Sainsburys but I made this cake today and it was my first total baking disaster. The whole thing fell apart. My husband described it more as a trifle than a cake. Tasty but very messy

I loved the look of the recipe and did it to impress the in laws on the weekend. I used toffee fudge sauce from Sainsburys which worked just as well. Only one problem which I think is me, I can never get any cake to rise. The banana cake was nice but quite stodgy.

My cooking is fine but when it comes to baking I am doing something very wrong - any ideas???

Simple to make, and I also used the Carnation Caramel. I found the cream section made it slightly sickly, so definitely small portions! The sponge is really great- I have been looking for a great banana sponge recipe so I'm delighted to have found this!

This cake was easy to make, although mine was like a muffin texture and rose a lot in the middle. I couldnt cut it into 3 layers as it didnt rise enough so just did 2.

The dulce de leche was hard to find, I used the Carnation Condensed Milk Caramel and some toffee sauce.

The cake was tasty in small portions.

Hi Laney... yes you can make dulce de leche from scratch...
You take about 1l of milk with half a kilo of sugar and make it boil until it dry onto dulce de leche...
It take's time, but you can do it...
A tip for you.... When sugar were completely melted, put a small plate into the pan... i know that it sounds strange but it'll keep milk from felt out of the pan. Take the plate off when you realize that the milk is getting thick. I hope you understand ether the recipe and my english!! Any doubt please let me know!
