Preheat the oven to 190°C/170°C fan, gas mark 5/375°F
Line a 12-hole muffin tin with paper cupcake or muffin cases.
For the cakes:
Put the cake ingredients into the bowl of a free-standing electric mixer (or you can use a handheld electric whisk and mixing bowl) and beat until light and creamy (1-2 minutes).(Butter, caster sugar, eggs, vanilla extract, flour, baking powder)
Alternatively, blitz all the cake ingredients in a food processor for 30 seconds, scrape down and blitz for a further 5 seconds
Divide the mixture evenly between the paper cases.
Bake in the preheated oven for 15–20 minutes or until well risen and the top of the cake bounces back when lightly pressed with your finger
Remove from the oven and leave to cool in the tin for 10 minutes
Transfer to a wire rack to cool completely.
For the chocolate buttercream:
Beat the butter until soft and creamy
Sift the icing sugar and cocoa powder, and add to the butter in two additions, mixing on a low speed, incorporating the milk, and beat for 3–5 minutes on a higher speed
Spoon the chocolate buttercream into a piping bag fitted with a star nozzle and pipe it onto the top of the cakes
Fill each 'nest' with three mini eggs.
