Warm molten-centered chocolate cupcakes

Jeremy bought new cookbook. It called perfect muffins & bakes. I decided to make this recipe for Alaric's ( Jeremy's brother) birthday celebration. We don't normal eat rich deserts but this was for special occasion.

Ingredients:

    * 4 tbsp margarine
    * 55 grans caster sugar
    * 1 large egg
    * 85 grams self raising flour
    * 1 tbsp cocoa powder
    * 55 grams plain chocolate
    * icing sugar for dusting


Method:

   1. Put 8 paper baking cases in a muffin pan.
   2. Put the margarine, sugar, egg, flour and cocoa in a large bowl and, using an electric hand whisk, beat together until just smooth.
   3. Spoon half of the mixture into the paper cases. Using a teaspoon, make an indentation in the center of each cake.
   4. Break the chocolate evenly into 8 squares and place a piece in each indentation, then spoon the remaining cake mixture on top.
   5. Bake the cupcakes in a preheated oven, 190C/375F, for 20 minutes or until well risen and springy to the touch.
   6. Leave the cupcakes for 2-3 minutes before serving warm, dusted with sifted icing sugar.
