Swirls of vanilla and chocolate cake batter combine to form the prettiest one layer Marble Cake with Chocolate Frosting.


Cake batter

  • 115 grams (1/2 cup or 1 stick) unsalted butter, room temperature
  • 150 grams (3/4 cup) caster sugar
  • 1 teaspoon vanilla extract
  • 1 large egg
  • 210 grams (1 and 1/2 cup) plain flour
  • 2 teaspoons baking powder
  • 240 ml (1 cup) milk
  • 60 ml (1/4 cup) natural yogurt
  • 1 tablespoon cocoa powder
  • 1 tablespoon milk

Chocolate frosting

  • 115 grams (1/2 cup or 1 stick) unsalted butter, room temperature
  • 100 grams (2/3 cup) good quality dark chocolate
  • 500 grams (4 cups) icing sugar
  • 60 ml (1/4 cup) milk
  • 1 tablespoon cocoa powder


  1. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Line and grease an 8-inch cake tin with baking or parchment paper.
  2. In a large mixing bowl, beat the butter and sugar together until pale and creamy. Add the vanilla and beat again. Add the egg, beat again, then scrape down the sides. In a separate bowl, sift the plain flour and baking powder together.
  3. Add half of the flour mixture to the butter and half of the milk and slow mix together on a low speed. Add the rest of the flour and the milk and continue to mix until combined. Finally, add the yogurt and mix until smooth and creamy.
  4. Remove 3/4 cup of the vanilla cake batter and add it to a separate bowl. To this, add the cocoa powder and extra tablespoon of milk. Stir until smooth.
  5. Add two tablespoons of vanilla cake batter to your prepared tin, followed by two tablespoons of chocolate. Continue with remaining cake batter, letting the cake batters swirl and combine. Bake for approximately 25-30 minutes or until a skewer inserted into the middle of the cake comes out clean. Leave to cool for 10 minutes before gently removing from the tin and leaving to cool completely on a wire rack.
  6. To make the frosting, place your softened butter in a large mixing bowl and beat with an electric mixer on medium speed for a couple of minutes until pale and creamy. Meanwhile melt the chocolate in a microwave, stirring in between 20 second bursts, until just melted and set aside to cool a little.
  7. Once the butter is very pale and creamy, add in half of the powdered sugar and two tablespoons of milk and beat until combined. Next, add the remaining sugar, cocoa powder and milk, and beat on slow until the sugar is incorporated before turning up to medium for another minute or so.
  8. Next, add in your melted chocolate to the buttercream mixture, ensuring the chocolate is still smooth and melted but is not warm. Beat until the chocolate is completely mixed through. Add frosting to cooled cake using a small spatula.
