Master the chocolate cake with an airy, light sponge and rich buttercream filling. It's simple enough for an afternoon tea but special enough for a party too

Heat oven to 190C/170C fan/gas 5. Butter the base and sides of two 20cm round sandwich tins and line the bases with baking parchment.
In a large bowl, beat together 200g golden caster sugar, 200g softened unsalted butter, 4 large eggs, 200g self-raising flour, 2 tbsp cocoa powder, 1 tsp baking powder, ½ tsp vanilla extract, 2 tbsp milk and a pinch of salt until pale.
Divide the mixture between the prepared tins. Bake for 20 mins or until a skewer inserted into the centre of the cake comes out clean.
Leave to cool in the tin for 10 mins, then turn out onto a wire rack to cool completely.
For the buttercream, put 100g chopped milk chocolate in a heatproof bowl and melt in the microwave, stirring every 30 secs. Leave the melted chocolate to cool for 5 mins.
