  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.

I've made this a couple of times now with excellent results. First of all I skip the marshmallows and I use Tesco Toffee Dessert sauce and it works great. I've done it as two cakes in two 8" tins and also as one big one sliced into three. It's much less fiddly as two 8" cakes. Either way, it's fantastic - I took one to work today and in less than half an hour there was nothing left but crumbs!

Before I tried this, I thought it might just be another banana loaf, but the overll effect of the cream and the caramel, just took it to another level. Very easy to make, no fuss at all. I did not have the right size tin, but my heartshaped tin was close enough in size, worked like a bomb! Very popular with my family, I iwll be making this again.

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.
