Not sure if you want a 'normal' cakey type cake but I have great flourless chocolate cake recipe that everyone loves. I put raspberries on top and you can serve it with chocolate sauce. Can post recipe if you like. It's really easy.
Preheat oven to 325/165 Grease 9inch/ 22.5 cm spring form pan. Line bottom Heat chocolate & butter over simmering water & melt until smooth ~ 5 mins In a separate bowl, combine eggs, sugar, vanilla & salt in large bowl and mix until doubled in size & frothy ~ 5 mins Fold egg mix into choc mixture 1/3 at a time Pour batter into pan Bake 45 50 mins until risen and set at edges*. Cool on wire rack. Invert on plate. Serve cold or at room temp. Top with raspberries and dust with icing sugar
Heat choc and cream in pan, mix well, serve in jug with cake.
* If it is still bit wobbly in the middle it is ok it will firm up as it cools. I often make this the night before and leave it in the fridge over night.
Here's the one I made for my birthday cake - I would halve the ingredients, it made two HUMUNGOUS cakes, so much so that I actually had 2 birthday cakes, 1 for friends/family, one for work!
I torted it into 3, spread with raspberry jam and then layered with 125g double cream whipped and 125g raspberries mashed into it, with a few tbsp icing sugar to stabilise it. Iced it with choc fudge ganache from Nigella's Feast, put choc fingers around the sides to tidy it up and then piled fresh raspberries on top - absolutely delish!
Everyone who ate it loved it - you only need little slices, it's so rich, but OMG it's lovely!
