2 cups sifted cake flour (I've used normal flour which resulted a denser texture)
1 cup castor sugar
2 tsp baking powder
1/2 tsp salt
1/2 cup butter, softened
1/2 cup milk
1 tsp vanilla essence
Whisk together flour, sugar, baking powder and salt. Using electric mixer on low speed, mix in butter, milk, eggs and vanilla essence. Beat on high speed until smooth, about 2 minutes.
Spoon into 12 paper lined or greased muffin cups, filling about 3/4 full. Bake in centre of oven at 190C about 18n minutes or test by inserting a skewer. If it's clean, then it's cooked. Transfer to rack and let cool completely.
I've chose not to iced them but feel free to do so.
