  • 5 Mars Bars
  • 125 g of butter
  • 1 1/2 tablespoons of golden syrup
  • 4 cups of puffed rice cereal
  • 400 g of milk chocolate


  • Line a 28 x 18cm tin with baking paper. Make sure you leave plenty of paper hanging over the sides to help you remove the Mars Bar Slice once it has set.
  • Place the butter, golden syrup and 4 of the Mars Bars (which have been chopped into quarters) into your Thermomix bowl and cook for 3 minutes, 60 degrees, speed 3. Scrape down the sides and cook for a further 1 minute if the ingredients haven't quite melted.
  • Add the rice cereal and mix for 10 seconds on speed 4 REVERSE. Scrape down the sides of the bowl and mix for a further 5 seconds on speed 4 REVERSE or until the rice cereal has been covered with the melted Mars Bar mixture.
  • Pour the mixture into your prepared slice tin and push down with the back of a metal spoon to flatten and smooth the surface.
  • In a clean Thermomix bowl, add the milk chocolate (which has been broken into pieces) and cook for 2 minutes at 50 degrees on speed 3. Scrape down the sides and cook for a further 1 - 2 minutes or until the chocolate has completely melted.
  • Pour the melted chocolate over the top of your Mars Bar Slice and decorate with pieces of the extra Mars Bar and place into the fridge for 4 hours to set.
  • Cut the set Thermomix Mars Bar Slice into pieces and enjoy!
