Marble Pound Cake
Yield: 1 9x5 loaf cake
  • ½ cup (1 stick) unsalted butter, room temperature
  • 1¾ cups cake flour
  • 2 teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup sugar
  • 3 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • ⅔ cup buttermilk, room temperature
  • ¼ cup plus 1 tablespoon Dutch-process cocoa powder
  • butter or spray for pan
  1. Preheat oven to 350 degrees. Generously butter or spray a 9-by-5-inch loaf pan; set aside.
  2. Whisk together the cake flour, baking powder, and salt; set aside.
  3. In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and sugar until light and fluffy, about 5 minutes. Add eggs, one at a time, beating until combined after each addition and scraping down the sides of the bowl as needed. Mix in vanilla. Add flour mixture in 3 batches, alternating with the buttermilk and beginning and ending with the flour.
  4. Scoop ⅓ of the batter into another bowl and set aside.
  5. In a separate small bowl, mix the cocoa powder and ¼ cup plus 2 tablespoons of boiling water until smooth. Add the cocoa mixture to the small bowl of cake batter; and stir it well.
  6. To assemble the cake- start by creating a checkerboard pattern in the bottom of the pan by spooning dollops of each batter on opposite sides of the pan. (see picture below recipe.)
  7. For the second layer, alternate the pattern, spooning vanilla batter over the chocolate and vice versa.
  8. Finish with a final layer of batter- again alternating it from the pattern of the 2nd layer.
  9. Use a knife or skewer to swirl all the batters together. Make a couple figure 8s and run it back and forth so it is swirled and pretty.
  10. Bake until a cake tester comes out clean, 40 to 60 minutes*. Transfer pan to a rack to cool 10 minutes. Turn out cake from pan and cool completely on the rack. Cake can be kept in an airtight container at room temperature up to 3 days.
* I know this is a wide range, but every oven is different. I needed the full 60 minutes for my cake to bake through. Start with 40 minutes and add more time as needed.
