Nigella's Old Fashion Chocolate Cake

INGREDIENTS:
200g plain flour
200g caster sugar
1 teaspoon baking powder
1/2 teaspoon bicarbonate of soda
40g best-quality cocoa
175g soft unsalted butter
2 large eggs
2 teaspoons real vanilla extract
150ml sour cream

FOR THE ICING:
75g unsalted butter
175g best quality dark chocolate, broken into small pieces
300g icing sugar
1 tablespoon golden syrup
125ml sour cream
1 teaspoon real vanilla extract
Sugar flowers, optional

METHOD:

Take everything out of the fridge so that all the ingredients can come to room temperature.
Preheat the oven to 180°C and line and butter two 20cm sandwich tins with removable bases.
Now all you have to do is put all the cake ingredients - flour, sugar, baking powder and bicarb, cocoa, butter, eggs, vanilla and sour cream - into a food processor and process until you have a smooth, thick batter.

Divide this batter, using a rubber spatula to help you scrape and spread, into the prepared tins and bake until a cake tester, or a thin skewer, comes out clean, which should be about 35 minutes, but it is wise to start checking at 25.

Remove the cakes, in their tins, to a wire rack and let cool for 10 minutes before turning out of their tins.

To make this icing, melt the butter and chocolate in a good-sized bowl either in the microwave or suspended over a pan of simmering water. Go slowly either way: you don't want any burning or seizing.

While the chocolate and butter are cooling a little, sieve the icing sugar into another bowl.

Add the golden syrup to the cooled chocolate mixture, followed by the sour cream and vanilla and then when all this is combined whisk in the sieved icing sugar.

When you've done, you may need to add a little boiling water - say a teaspoon or so - or indeed some more icing sugar: it depends on whether you need the icing to be runnier or thicker; or indeed it may be right as it is. It should be liquid enough to coat easily, but thick enough not to drip off.

Spoon about a third of the icing on to the centre of the cake half and spread with a knife or spatula until you cover the top of it evenly. Sit the other cake on top, normal way up, pressing gently to sandwich the two together.

Spoon another third of the icing on to the top of the cake and spread it in a swirly, textured way (though you can go for a smooth finish if you prefer, and have the patience). Spread the sides of the cake with the remaining icing and leave a few minutes till set, then carefully pull away the paper strips.

Eat all by yourself. Or, if you're nice, share. It's good!
