Chocolate and Vanilla Marble Loaf Cake


This Chocolate and Vanilla Marble Loaf Cake is thick and rich in butter combined into one decadent and to-die-for cake!


  • 1 ¾ cup all-purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon salt (or less depending on taste)
  • 1 cup castor sugar
  • ½ cup butter (1 stick)
  • 3 eggs
  • 1 teaspoon vanilla essence
  • 2/3 cup buttermilk
  • Cocoa paste (¼ cup cocoa + 2 tablespoons boiling water. Stir till smooth)


  1. Preheat oven to 350 degrees C. Line the bottom and grease the sides of one 9×5 inch loaf pan.
  2. Whisk together first three ingredients in a large bowl.
  3. Beat butter and sugar till light and fluffy. Add eggs, one at a time, beating well. Add vanilla essence.
  4. Add flour mixture in two batches, alternating with buttermilk.
  5. Set aside 1/3 of this batter.
  6. Add cocoa paste to the reserved batter and stir till well combined.
  7. Spoon the batters in the prepared pan. Add one tablespoon of vanilla batter followed by the chocolate batter. Level the top with a spoon. Run a table knife or the back of a spoon in swirling motion through the batters to get to get a marbling effect.
  8. Bake for 45 to 50 minutes or until a toothpick inserted in the center comes out clean. Transfer pan to a rack to cool for 10 minutes. Turn out the cake from pan and cool completely on the rack.
