Equipment

  • 2 x 20cm round cake tins
  • Large mixing bowl
  • Jug
  • Whisk
  • Glass bowl for double boiler

Ingredients

  • 225 g plain flour sifted
  • 350 g caster sugar
  • 85 g cocoa powder
  • 1.5 tsp baking powder
  • 1.5 tsp baking soda
  • 250 ml whole milk at room temperature
  • 2 eggs
  • 125 ml vegetable oil
  • 250 ml cold coffee
  • 250 g dark chocolate chopped
  • 250 g milk chocolate chopped
  • 100 g unsalted butter
  • 200 g malted milk biscuits roughly broken
  • 100 g mini marshmallows
  • 100 g mixed nuts (hazelnuts, almonds, macadamias)
  • 100 g Maltesers roughly broken up
  • 1 tub marshmallow fluff
  • 200 ml whipped cream
  • q.s. extra mini marshmallows for decoration
  • 3 tbsp icing sugar

Instructions

  • Preheat your oven to 180°C / 160°C fan / gas 4 and grease the base and sides of 2 x 20cm round cake tins.
  • In a large bowl, whisk together the flour, sugar, cocoa, baking powder, and baking soda.
  • In a separate jug, whisk together the milk, eggs, and oil until combined. Add this mixture to the dry ingredients and whisk until smooth.
  • Mix boiling water and coffee powder together, then pour it into the batter and mix until combined.
  • Divide the batter evenly between the prepared cake tins and bake for 20-25 minutes until a skewer inserted comes out clean. Let cool completely in the tins.
  • While cooling, melt both chocolates and butter in a glass bowl over a double boiler, then add biscuits, marshmallows, and nuts. Mix well.
  • Pour the rocky road mixture over the cooled cakes, spread evenly, and refrigerate for about 2 hours to set. Once set, turn one cake onto a serving plate, spread marshmallow fluff on top, and place the second cake on top. Decorate with whipped cream rosettes, extra mini marshmallows, and a dusting of icing sugar.

Notes

Use high-quality chocolate for the best flavor. Ensure cakes are completely cool before adding the rocky road mixture to avoid melting. For a neat presentation, use a piping bag for the cream rosettes. Store in an airtight container in the fridge for up to 5 days or freeze individual slices wrapped in plastic. Thaw at room temperature before serving.
