When I make these for sale, I get asked what's in them....my answer is always - nothing good for you and that's why they're so delicious!
Line a 8" x 8" Baking Tin with grease-proof paper
Break up the chocolate and place it in a bowl with the butter and golden syrup
In 30 second bursts, melt on high power in the microwave. Checking and stirring every 30 seconds to ensure the chocolate isn't burning
Once all melted mix in the broken biscuits and then the marshmallows
Pour into the baking tin and pat down to the edges
Whilst the chocolate is still liquid scatter on your toppings - pick'n'Mix is my favourite, but you can use sprinkles, M&Ms, or any sweets and candy you like
Put in the fridge for at least an hour to set
Remove from the tin and slice up....seriously, its that easy!!
