  • 1 cup of Maltesers plus extra to decorate grab a 280g pack
  • 4 Mars Bars 4 x 53g bars
  • ½ cup Condensed Milk 125ml
  • 1 pack of Chocolate Ripple Biscuits 250g
  • 2 blocks of Cadbury Milk Chocolate 2 x 200g blocks
  • 100 g unsalted butter
  • 1 teaspoon vegetable oil


  • Line the base and sides of a slice tin with baking paper.
  • Finely crush the Chocolate Ripple Biscuits. You can use a food processor or the end of a rolling pin if you are like me!
  • Roughly crush 1 cup of Maltesers.
  • Dice the Mars Bars into small pieces.
  • In a small saucepan over a low heat, melt the butter and condensed milk, stirring until combined.
  • Add the roughly crushed Maltesers and Mars Bars to the crushed biscuits and stir through.  Then add the melted butter and condensed milk and stir until combined - it will be very sticky!
  • Pour the mixture into the slice tin and flatten with the back of a metal spoon.  Pop it in the fridge for approximately an hour until it has completely cooled.
  • Melt both of the blocks of chocolate and add 1 teaspoon of vegetable oil to the melted mixture, making sure you stir it in.
  • Pour the melted chocolate over the cooled slice and then decorate with remaining Maltesers.
  • Put the slice back into the fridge and cut into pieces before it has completely set.
