NIGELLA'S OLD FASHIONED CHOCOLATE CUPCAKE

Ingredients :
(Recipe adapted from here)
Makes about 8 slices (or about 12 cupcakes).
For the cake
- 200g plain flour
- 200g caster sugar (I reduced to 140g)
- 1 tsp baking powder
- 1/2 tsp bicarbonate of soda (baking soda)
- 40g best quality cocoa (I used Valrhona for best results)
- 175g soft unsalted butter
- 2 large eggs (or 3 medium eggs like I did)
- 2 tsp real vanilla extract
- 150ml sour cream

For the icing (I skipped this)
- 75g unsalted butter
- 175g best quality dark chocolate, broken into small pieces (I used Valrhona Caraïbe 66%)
- 300g icing sugar
- 1 tbsp golden syrup (this gives the lovely sheen to the icing, but it is optional, in my opinion)
- 125ml sour cream
- 1 tsp real vanilla extract
