Preheat your oven to 180°C (350°F). Grease and flour a 9-inch loaf pan.
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
In another bowl, sift together the flour, baking powder, and salt.
Gradually add the dry ingredients to the creamed mixture, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
Divide the batter into two equal parts. Stir the cocoa powder into one part of the batter.
Spoon the batters alternately into the prepared loaf pan, then use a knife to swirl through the batter to create a marbled effect.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Allow the cake to cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely before serving.
