Execution
Follow the master commands
Heat the oven to 180C/160C fan/gas 4. Melt 25g butter and generously brush into the holes of a mini bundt tins. Tip a little flour into each hole and shake to coat, then tip out the excess. Beat the butter, caster sugar and a pinch of salt together using an electric whisk. Add the eggs, one at a time, beating well after each addition. Combine the flour and baking powder in a separate bowl, then sift this into the wet ingredients and stir until smooth. Combine the cocoa powder and milk in a small bowl until smooth.
Spoon 1 tbsp of the plain batter into each hole of the bundt tin. Mix the remaining plain batter with the cocoa powder mixture, then divide this between the holes. Bake for 15-18 mins, or until a skewer inserted into the cakes comes out clean. Leave to cool in the tin for 5 mins, then turn out onto a wire rack and leave to cool completely. Dust with icing sugar to serve.
