  • 100 g/ ⅗ oz Butter
  • 300 g/ 10 1.2 oz Dark Chocolate (around 60% is fine)
  • 1 tablespoon Golden syrup (light corn syrup)
  • 1 Egg
  • 160 g/ 5 ½ oz Mint biscuits (I used 6 Viscounts & 6 Mint Oreo biscuits)
  • 100 g/ 3 ½ Fry's Peppermint Creams (or other mint fondant cream in dark chocolate)
  • 80 g/ 3 oz Mint Aero Bubbles (or other Mint chocolate)


  • Grease a small loaf tin (1kg) and line it neatly with baking parchment
  • Put the butter, dark chocolate and syrup into a medium heatproof mixing bowl and suspend over a pan of barely simmering water (ensure the water does not touch the bottom of the bowl). Stir until melted
  • Crack the egg into a jug, whisk briefly and stir into the chocolate batter. Remove the bowl from the heat and let cool for 15 minutes, stirring once or twice
  • Meanwhile break the biscuits into chunks (6-8 per biscuit) - scoop all the chunks and crumbs into a bowl
  • Chop the peppermint creams into pieces but leave the Aero Bubbles intact
  • When ready, tip the biscuit pieces into the chocolate batter and briefly stir with a large metal spoon to combine - 4 or 5 turns should be sufficient
  • Spoon ¼ of this mix into the base of the loaf tin, ensuring the mix reaches the corners of the tin
  • Spread ⅓ of the peppermint cream chunks and ⅓ of the Aero Bubbles over the base and top with another ¼ of the chocolate batter. Take care to ensure that the batter reaches the corner and the layer of peppermint chocolates are covered - use the back of a small metal spoon to guide the mix into empty spaces 
  • Repeat with another ⅓ of the peppermint creams and Aero Bubbles and top with another ¼ of chocolate batter
  • Spread the remaining mint chocolates on the top and cover completely with the final ¼ of the batter. Carefully level using the back of a metal spoon
  • Wrap the tin in clingfilm and transfer to the fridge for around 6 hours to set
  • When ready, carefully remove from the loaf tin, remove the parchment and cut into 10-12 slices
  • Store in the fridge for up to 1 week. Remove from fridge 15 minutes before serving
