Chocolate Marble Cake

Instructions

1. 1

   Preheat your oven to 175°C (350°F). Grease and flour a loaf pan or line it with parchment paper.

2. 2

   In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside.

3. 3

   In a large bowl, beat the eggs and granulated sugar together until light and fluffy.

4. 4

   Add the sour cream, vegetable oil, and vanilla extract to the egg mixture. Mix until well combined.

5. 5

   Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.

6. 6

   Divide the batter evenly into two bowls. In one bowl, sift in the unsweetened cocoa powder and mix until fully incorporated.

7. 7

   Alternate spoonfuls of the plain and chocolate batters into the prepared loaf pan. Use a knife or skewer to gently swirl the batters together to create a marbled effect.

8. 8

   Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.

9. 9

   Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing and serving.
