There seems to be a lot of ingredients, but it's not difficult to make, tho' it is a bit more effort than a chocolate sponge. The original recipe was of course in cups, hence the strange amounts.
It's quite a big cake, so one to make for an occasion [and not if you're on a diet!].
Preheat oven 160C/gas3
Grease a 23cm/9" springform tin or tube pan, and line the base with baking paper. Dust inside of tin with flour and shake out excess.
2 tspn instant coffee granules
2 tsps vanilla extract
1/4 tspn hot water
330g plain flour
30g sr flour
40g + 1 tbspn cocoa powder
1/4 tspn baking powder
1/4 tspn bicarbonate of soda
1 tspn salt
320g dark chocolate chips [ if they're large, chop them up]
300g granulated sugar
100g light brown sugar
250ml sour cream
2tbspn double cream
Stir the coffee, vanilla and hot water together.
In a large bowl, sift the plain flour, sr flour, cocoa, baking powder and bicarb and salt together.
In another bowl mix the chocolate chips with 1 tbspn of the flour mixture.
In a mixer, or with an electric hand beater cream the butter; scrape the sides then add the granulated sugar a bit at a time. Add the brown sugar and beat together.
Add the eggs one at a time and mix in the coffee mixture.
Then add the flour mixture carefully, alternating it with some sour cream, scraping the sides to make sure it's all mixed in. Add the double cream, and finally mix in the chocolate chips using a wooden spoon or spatula.
Spoon into the tin.
Bake for about 70 mins till the cake is coming away from the sides.
Cool in the tin for 15 mins then invert onto a wire rack; take the paper off, then invert it right side up and leave to cool.
You can leave the cake as it is or make a simple chocolate ganache with 300ml double cream and 200g dark chocolate.
Put the chocolate in a bowl, then warm the cream - but don't let it boil.
Pour the cream over the chocolate, leave for a minute then gently stir together.
Let the ganache cool to room temperature then pour it over the cake.
This is a very rich, decadent cake, but lovely for a birthday or other special occasion. If you made it without the tube, you could cut it in half and make a filling of your choice. Oh, one thing to be careful of, when you're pouring the ganache over the cake, make sure that you have a tray or something underneath or it goes everywhere! I learnt that the hard way!
