Melt your chocolate in a microwave safe bowl in 10-second bursts or until it's completely melted. Stir in the butter until it's completely smooth and then stir in the brown sugar. Leave to cool
Whisk the vanilla into the egg and then mix these into the cooled butter/brown sugar/chocolate mixture.
Sift the flour and bicarb soda into the chocolate mix and stir with a wooden spoon until it comes together. Cover with plastic wrap and put in the fridge for 30 minutes
Preheat the oven to 200 degrees celsius and then pour the icing sugar into a shallow dish
Divide the dough into 30 equal size balls and roll these in the icing sugar, coating them thickly. Set them on baking paper-lined cookie sheets, giving them space to spread
Bake for 10 minutes. When you remove them from the oven, sprinkle with salt and then leave for a further 30 seconds before moving them to a wire rack to cool. Biscuits will keep in an airtight container for 5 days
