100gMini Marshmallow or chopped larger marshmallowsee recipe
Instructions
Melt the butter, chocolate and golden syrup in a heavy-based saucepan. Scoop out about 125ml of this melted mixture and put to one side.
Put the biscotti into a freezer bag and then bash them with a rolling pin. You are aiming for both crumbs and pieces of biscuits.
Fold the biscuit pieces and crumbs into the melted chocolate mixture in the saucepan, and then add the marshmallows.
Tip into a tray (24cm / 9 inch square) lined with greaseproof paper. Flatten as best you can with a spatula. Pour the reserved 125ml / ½ cup of melted chocolate mixture over the marshmallow mixture and smooth the top.
