This cake is properly low-fat (unlike this pretender). Amazingly, there is no fat in the cake itself apart from the eggs, and not much at all in the icing. In fact, I was so worried about the cake being too dry that I added the crème fraiche and raspberries at the last minute, which I figured would make it more palatable as well as looking prettier. Actually it turned out quite nice and soft (if slightly chewy), and very light, despite collapsing in the middle a bit! Nothing a dollop of crème fraiche couldn't disguise...
3 large eggs
85g golden caster sugar
70g plain flour
1 tbsp cornflour
2 tbsp cocoa
½ tsp baking powder
For the icing:
40g dark chocolate
1 tbsp strong black coffee
100g low-fat yogurt
2 tbsp icing sugar
Low fat crème fraiche
raspberries (or any other berries/fruit pieces)
Heat oven to 180c. Lightly grease and line the base of circular cake tin. Whisk the eggs and sugar until light and fluffy (takes about 10 mins using an electric hand whisk). Mine never quite got beyond the frothy stage, so I would recommend whizzing the eggs before adding the sugar.
Sift the flour, cornflour, cocoa and baking powder and fold in gently. Pour mixture into the tin and bake about 25-30 mins, or until it is well risen and has begun to shrink away from the sides of the tin.
Microwave the chocolate and coffee together for 20-30 seconds until the chocolate has melted. Gently stir until smooth, then cool slightly. Beat the yogurt and icing sugar until smooth, then mix in the chocolate and spread over the top, letting it run down the sides.
I let the icing set in the fridge overnight, then added the crème fraiche and raspberries before serving.
