READY IN: 40mins


  • 1
    cup superfine sugar
  • 14
    cup vegetable oil
  • 14
  • 1
    cup orange juice
  • 2 12
    teaspoons baking powder
  • 4
    tablespoons unsweetened cocoa powder, depending on the contrast you desire in your cake (you can add less (or more)
  • 1
    orange, zest of (optional)


  • NOTE: My original recipe used less baking powder and I found that it didn't rise very much,so I increased the amount of baking powder.
  • In a medium bowl ,whisk the eggs with the sugar,sour cream,oil,and orange juice.Add orange zest at this point if using any.
  • In a separate bowl ,sift the flour and baking powder and gently mix together to evenly incorporate the baking powder into the flour.
  • Slowly add the egg mixture into the dry ingredients and mix until everything is combined.
  • Next, pour half of the batter into a separate bowl and add cocoa powder to it.If the cocoa mixture has a thicker consistency,then you can add a little bit of orange juice to thin it out.
  • Lightly grease a 9 inch round or square cake pan and pour the batter interchangeably to get a marble or swirl effect.This is where you can get creative.
  • Bake at 350 degrees F for 40 minutes or until tester comes out clean.
