Method
- Preheat the oven to 160 fan and grease and line 2 x 24 cm spring form cake tins.
- Chuck the flour, cocoa powder, baking powder, bicarbonate of soda, golden caster sugar into a large mixing bowl. Mix and then add the eggs, milk, vegetable oil, a pinch of salt and water. Mix until incorporated. Don’t be alarmed, it will be very runny.
- Divide the mixture between the two cake tins and bake for 30-35 minutes or until a skewer comes out almost clean from the centre. Leave to cool for 10 minutes and then remove from the tins and cool completely.
- To the make the buttercream, melt the chocolate and then set to one side to cool completely. Beat the butter for 3-5 minutes until pale. Add 1/2 the icing sugar and beat until combined. Add the remaining sugar, coco powder, milk and chocolate and whisk until smooth.
- Place one of the cakes onto a stand and spread over half the buttercream. Place the other cake over the top and cover with the remaining buttercream. Smooth out and serve immediately.
