Preheat the oven to Gas 4, 180°C, fan 160°C and line a 20cm (8in) round cake tin.
Put the chocolate and 1 tablespoon of the milk into a small bowl and melt over a pan of hot water. Take care not to let the water boil.
In a large mixing bowl, beat together the eggs, oil, milk and sugar.
Sieve together the flour, baking powder and salt and beat into the wet ingredients.
When the chocolate has melted, add to the mixing bowl and beat until all ingredients are combined.
Pour the mixture into the lined cake tin and bake for 45 minutes or until a knife inserted into the centre comes out clean.
Turn out onto a wire cooling rack and allow to cool.
This is a one bowl cake mix with no saturated fat. You can omit the chocolate and add the zest of 2 lemons and change the 5 tablespoons of milk to 5 of milk and one of lemon juice. I make some icing with icing sugar and lemon juice to spread over the top.
Alternatively, omit the chocolate and add 2 fresh pears, peeled and cut into small pieces and just add to the cake mix. It produces a lovely moist cake with chunks of pear at the bottom.
