Cupcake cases - place in a muffin tin

Pre-heat oven 190C(170 fan)/375F/Gas 5

Cream butter and caster together until light and fluffy (if you have a mixer use it :-)

Add the beaten egg slowly, careful it doesn't curdle if it does add a couple of spoons of flour, whisk well

Add the vanilla and whisk

Finally fold in the flour with a wooden spoon, followed by the chocolate chunks - mix well

Half fill the cases with the cake batter and bake for 20-25 mins on the middle shelf, until golden & firm to touch keep your eye on them.

Remove from the oven and leave to cool

Make the Butter Icing by creaming the butter and icing sugar until smooth, add a drop of milk until you have the desired consistency (again use an electric mixer if you have one)

Finally stir in the melted chocolate until smooth & glossy

Pipe on top of the cooled cupcakes and decorate however you like …… Enjoy!
