Ingredients:
200g butter (softened)
200g sugar
4 eggs
200g flour
1 tsp baking powder
1 tsp vanilla extract
2 tbsp cocoa powder
2 tbsp milk (optional, for a moister texture)

Marble the batter: Spoon alternating dollops of vanilla and chocolate batter into the pan, then swirl gently with a knife or skewer.
