This marble pound cake recipe is perfect for those who love a dense and buttery cake. It's made with simple ingredients like flour, sugar, butter, and eggs. To make the cake, start by creaming butter and sugar together until light and fluffy. Then add eggs, one at a time, followed by vanilla extract. In a separate bowl, whisk together flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, alternating with milk. Finally, divide the batter in half and mix cocoa powder into one half. Pour the vanilla and chocolate batter into a greased loaf pan, alternating between the two. Use a knife to swirl the batter together to create a marble effect. Bake for 60-70 minutes at 350°F. Let the cake cool before slicing and serving.
