Begin by preheating your oven to 350°F. Either grease two 12-cup muffin tins or line them with paper liners.

In a large bowl, cream together the butter and sugar until the mixture is light and fluffy. Gradually mix in half of the flour and two eggs, beating well after each addition. Then, incorporate the remaining flour and eggs, continuing to beat until the batter is smooth and airy.

Spoon the batter into the prepared muffin cups, filling each about three-quarters full. Bake in the preheated oven for 10 to 12 minutes, or until the tops of the cakes spring back when lightly pressed.

Allow the cakes to cool in the tins for 5 minutes, then transfer them to a wire rack to cool completely. Once cooled, decorate with your choice of simple icing or sprinkles, keeping the decorations light to maintain the fairy cake's traditional look​​.
