Crush the digestive biscuits using a rolling pin in a sealed packet or bag.
In a large saucepan, melt the butter and chocolate over warm water (or melt in a microwave).
Add the crushed digestive biscuits, golden syrup and 2 ½ packets of the delishios to the melted chocolate and stir well.
Place the mixture into a square 20 cm x 20 cm baking pan. Top with the remaining delishios then place in the fridge to chill for a couple of hours.
Once chilled, slice into squares and serve.
