INGREDIENTS

INSTRUCTIONS

  • Line a 11x7 inch baking tray with some greaseproof paper and set aside.
  • In a large bowl, melt the butter/margarine and Mars Bars over a bain marie or in short bursts in a microwave. Use the back of a spoon/spatula to break up the nougat, as this won't melt as well - don't worry about lumps though, it won't be perfectly smooth.
  • Add the rice crispies to the melted ingredients and mix well, ensuring all are coated.
  • Tip into your prepared baking tray and push down with the back of a spoon/spatula, ensuring an even finish right into the corners.
  • Melt the milk chocolate over a bain marie or in short bursts in the microwave before spreading over the top of your rice crispy base.
  • Place into the fridge to set for at least a few hours or ideally overnight. Cut into your desired portion sizes to serve.

IMPORTANT NOTE:

All my recipes are developed using a digital scale and the metric system (grams and millilitres). Cup measurements are available as a conversion but these, unfortunately, won't always be as accurate. For best results, I always recommend baking with a digital scale.

RECIPE NOTES:

  • For full ingredients information and substitutions, please see the Ingredients Explanation above.
  • If using full sized Mars Bars (51g) you will need a little under five Mars Bars. If you are using multi-pack Mars Bars (usually about 40g each) you will need about 6 Mars Bars.
