Ingredients
  

  • 250 g Toffees Sainsbury’s Basics
  • 50 g Butter room temperature
  • 3 tbsp of milk
  • 1 tbsp of golden syrup
  • 115 g Marshmallows
  • 175 g Rice Crispies or similar cereal

Instructions
 

  • Brush your desired tin or mould with baking spray or oil and wipe with a kitchen towel to make sure it is not too oily. If you use silicone moulds always brush them lightly with cake release spray and then wipe off the excess with a kitchen towel even for cakes, choclates etc then your crispy treats will fly out of the moulds unlike one born every minute.
  • Add toffee, golden syrup, butter and milk into a saucepan and heat gently. Stir the mixture as it heats until all the ingredients have melted.
  • Add marshmallows and stir until they have melted.
  • Add the cereal to the pan and make sure it is all well coated with the toffee mixture
  • Pour quickly into the tin or mould and level (it will stick to everything in my experience leaving wispy marshmallow strands everywhere)
  • Leave to set (about an hour) and drizzle with what ever chocolate you fancy but they are just as nice without too. Cut into sizes required and eat (one is not enough) they will keep for about 5 days if they get that long in an air tight container.
