Ingredients (1 loaf)
For the Base Batter
- 1/2 cup (1 stick) unsalted butter, at room temperature
- 3/4 cup granulated sugar
- 2 large eggs, at room temperature
- 1 1/2 cups all-purpose flour
- 1 1/4 teaspoons baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon Diamond Crystal kosher salt
- 3 tablespoons whole milk
For the Flavorings
- 1 1/2 teaspoons vanilla extract
- 2 tablespoons unsweetened cocoa powder
- 1 tablespoon whole milk
Combine The Baking Ingredients
Be sure to preheat your oven to 390F before beginning your cake.
Grease and flour an 8×4-inch loaf pan as well.
You want to get both of your butter and eggs at room temperature before using them.
This will allow for better mixing of the two ingredients so that you will have a softer cake.
Mix the all-purpose flour, baking powder, baking soda, and salt together in a medium mixing bowl.
In a stand mixer bowl, cream your room temperature butter with your granulated sugar on medium speed for about 3-4 minutes, or until your mixture is light and fluffy.
With your stand mixer still running, add the eggs one at a time, beating them well into the mixture after each addition.
Add the dry ingredients to your mixture in three additions, alternating the dry ingredients with the three tablespoons of milk, starting and ending with the dry ingredients.
Mix each addition just until the flour has been fully incorporated.
Be sure to mix only until the flour has just been incorporated; if you overmix your batter after adding the flour, your cake will be tough.
Separate, Layer, And Create A Marble Cake
Separate the batter into two even bowls.
To one of the bowls, add vanilla extract.
To the other bowl, add cocoa powder and the additional one tablespoon of milk.
Stir until fully blended.
Spoon 1/3 of the vanilla batter into your prepared loaf pan and spread it out evenly in the pan.
Then drop the same amount of the chocolate batter on top of the vanilla batter.
Repeat this layering process until you use all the batter from both bowls.
To achieve a marble cake effect, run a butter knife through the batter in an “S” shape lengthwise only once.
Bake The Cake
Bake your cake for 10 minutes at 390F in a preheated oven.
Lower the temperature to 350F and continue to bake the cake for an additional 30-35 minutes, or until a toothpick inserted into the center of the cake comes out clean.
Cool in the pan for 10 minutes, then remove and cool completely on a wire rack.
