For the batter: – butter – sugar – eggs
Preheat the oven to 180°C (350°F). Grease and line a 20-22 cm (8-9 inch) cake pan with parchment paper. In a large bowl, cream the butter and sugar together until light and fluffy.
Gradually incorporate the dry ingredients into the butter mixture, alternating with the milk. Mix until smooth. Split the batter into two equal portions.
