Preheat the oven to 190C/375F/Gas mark 5. Prepare your cupcake tray with the cases needed.

Put the butter/margarine in with the caster sugar and use an electric whisk to beat until light and fluffy.

Slowly whisk in the eggs a bit at a time so that they don't curdle. Once fully whisked add the vanilla essence.

Sift the flour into the mixture and fold it using a spatula so as to get all of the flour mixed. Once consistent, add the chocolate chips and fold them in as well.

Use two tea spoons to spoon the mixture into the cases until they're 3/4 full. Place in the oven for 15-20 minutes, check regularly with a cocktail stick (if they are undercooked the cocktail stick will come out with mixture on it). Once cupcakes are done place on a cooling rack until cool.

Dust with icing sugar and enjoy!
