Chocolate Crackles

This recipe is from 'The Great British Bake Off' cook book. I can't stop eating these little treats. 

Ingredients

100g dark chocolate (70% cocoa solids)

100g unsalted butter

150g light brown muscavado sugar 

1 large egg

½ tsp vanilla extract 

175g self raising flour

½ tsp bicarbonate of soda

2-3 tbsp icing sugar 

Break the chocolate into pieces and melt in a glass bowl, over a pan of simmering water. Once the chocolate has melted, take the bowl from the heat and stir in the butter. When the butter is smoothly incorporated, stir in the sugar. Leave to cool for 5 minutes. When the mixture has cooled, beat in the egg and the vanilla extract. Then, sift in the flour and bicarbonate of soda and mix with a wooden spoon. Cover the mixture with cling film and chill for 1 hour. After 1 hour, preheat the oven to 200°C and grease two baking trays. Divide the biscuit mixture into 30 pieces and roll each piece into a little ball. Place the icing sugar in a shallow dish and roll each biscuit dough ball into the icing sugar until well coated. Place the balls on the baking trays. Pop in the oven and bake for 10 minutes. Remove and leave to cool on a wire rack. Put some in your tummy.
