Think they must have about 1000 cals per chunk. Basic choc brownie recipe. Then you melt 300 g dark choc, 100g butter and 3tbsp golden syrup. Wait til the brownie and the choc mixture are cool and stir through malteasers, chopped up marshmallows and raisins. Spread over the cake and set in the fridge.
These are for the refreshment stall at Pre school's Xmas market - hoping they will sell well
