What you need:
Preheat your oven.
Beat the butter and icing sugar together until the mixture is pale and creamy. Gradually beat in the egg yolks and vanilla essence. Slowly beat in the self-raising flour and cornflour until the mixture is smooth.
Spoon the mixture into a piping bag with a star nozzle. Pipe a double thickness of circles of the mixture in cup cake cases. In the centre place a blackberry or two.
Bake in the oven for 15 minutes, or until golden. Leave to cool and dust with some icing sugar.
