Marble Pound Cake

  • 1 ½ cups granulated sugar
  • 1 ½ cups unsalted butter softened
  • 1 teaspoons fine sea salt
  • 1 tablespoon pure vanilla extract
  • 4 large eggs plus 2 egg yolks
  • ¼ cup plus 2 tablespoons sour cream
  • 1 cup plus 2 tablespoons cake flour
  • ½ cup cake flour
  • cup dutch process cocoa powder

Chocolate Glaze

  • 1 cup organic powdered sugar
  • 3 tablespoons cocoa powder
  • Pinch fine sea salt
  • 2 tablespoons milk
  • Flaked sea salt for topping


  • Preheat the oven to 350 F. Grease and flour a 10 cup bundt pan.
  • If your eggs aren’t at room temp, set them in a bowl of warm water.
  • In the bowl of a stand mixer, beat together the sugar, butter, salt and vanilla for a full 10 minutes, the mixture should be very light and fluffy.
  • With the mixer on low, one by one add the eggs and yolks, allowing time for each to fully incorporate before adding another.
  • Add the sour cream and beat to combine.
  • Divide batter in half (use a scale if you have it for accuracy).
  • To one half sift in ½ cup cake flour and cocoa. To the other half sift in 1 cup flour and 2 tablespoons of cake flour.
  • Layer the batter into the bundt pan, alternating between the chocolate and the plain (you should get about 3 layers from each for a total of 6-7 layers, extras can be added on top).
  • Bake for 50-60 minutes, until you can press the top and it feels firm, or use a cake tester.
  • Let cool in the pan for 5 minutes then overturn onto a cooling rack.
  • Once completely cool, make the glaze by whisking all the ingredients together. If the glaze is thick, add a bit more milk, if it’s too thin, add more powdered sugar (or cocoa).
  • Spoon glaze on top of bundt and sprinkle with flaked sea salt.
