Whisk ground sugar and butter thoroughly in a bowl.

Add eggs one at a time and whisk thoroughly. Add essence. You may add all the eggs together if you are going to whisk with a machine.

Add the flour a little at a time and again whisk thoroughly.

Add a little milk if you find the consistency of the mixture hard.

Taking a round spoon pour sufficient quantity of the mixture into paper cake cups ensuring not to fill to the top as this would otherwise overflow during baking.

Bake at 150°C for 30-40 minutes.
