For the chocolate sponge:

  • butter, for greasing
  • 225 g soft brown sugar
  • 4 large eggs
  • 250 ml vegetable oil
  • 1 tsp vanilla extract
  • 175 g self-raising flour
  • 75 g cocoa powder
  • 1 tsp baking powder
  • 1 tsp bicarbonate of soda
  • 45 ml buttermilk
  • 397 g dulce de leche or Carnation caramel

For the fudge icing:

  • 100 g dark chocolate, at least 70% cocoa solids
  • 150 g unsalted butter, at room temperature
  • 450 g icing sugar
  • 50 ml milk
  • 2 x 126 g rolos, to decorate


1. For the cakes: Preheat the oven to 180C/160C fan/gas 4 and grease two 18cm sandwich tins and line the bases with greaseproof paper.

2. Using an electric whisk or a stand mixer, beat the soft brown sugar and eggs and together for about four minutes until pale and creamy. Slowly add the vegetable oil and the vanilla bean paste and mix again.

3. Sift in the flour, cocoa powder, baking powder, bicarbonate of soda and stir together well with a metal spoon. Add a pinch of salt and stir in the buttermilk, mix well.

4. Divide the mixture equally into the prepared baking tins and bake for 30 minutes, checking after 25 minutes to see whether a cocktail stick comes out clean. Once cooked, take the sponges out of the oven. Leave to cool in the tins and then turn the sponges out onto a wire rack.

5. For the fudge icing: Over a pan of gently simmering water in a heatproof bowl, melt the chocolate and set to one side. In a stand mixer, whisk the butter until light and fluffy and gradually add the icing sugar. Add the melted chocolate and keep mixing until the mixture is smooth. Add the milk to loosen the icing slightly, if needed.

6. Once the cakes have cooled, spread ¾ of the can of caramel sauce over the bottom layer of the cake, reserving the rest for the topping. Place the second cake on top and spread half of the fudge icing all over the cake. Smooth with a palette knife and then continue icing the cake until covered all over.

7. Gently heat the remaining caramel sauce to make it easier to pour. Leave to cool slightly. Pile the Rolos onto the middle of the cake and drizzle over the caramel sauce with a spoon.
