550g milk chocolate (chips or bars chopped into small pieces)
150g Dark chocolate
100g mini marshmallows
220g broken biscuit pieces (I used a mix of malted milk, digestives, bourbons and viennese whirls)
Start by gently melting the chocolates in a large bowl either over a pan of simmering water or in the micro.
Line your brownie pan with parchment, using a third of melted chocolate pour a layer into the pan, add half of the broken biscuits and a third of the mini marshmallows, cover with a third of the melted chocolate. Repeat the process, finish with the remaining marshmallows.
Place in the fridge for at least 60 minutes, now using a kitchen blowtorch burnish the marshmallows gently, cut into 9 squares, and set in the fridge for a few minutes to firm before serving.
*If you don't have a blowtorch you can pop under a hot grill to burnish the top BUT pop into the freezer for half an hour before so the chocolate doesn't melt completely and watch the whole time as the marshmallows catch very quickly xx
