How to Make a Classic Black and White Marble Cake

This Black and White Marble Cake is the ultimate marble pound cake: dense, moist, and tender, with a beautiful marbled interior and rich chocolate flavor.

What is Black and White Marble Cake? It’s a classic marble pound cake made from a single vanilla-based batter divided into two portions, one blended with melted white chocolate and the other with semisweet chocolate, then layered and swirled together for a striking contrast of flavors and color.

The method is simple: prepare a smooth pound-cake-style batter, divide it, fold melted chocolates into each half, then dollop and swirl the two batters in the pan to create the marble effect. This cake travels well and holds its texture and flavor, making it perfect for gifting or taking to gatherings.

Ingredients for Marble Cake

All-purpose flour
Baking powder
Salt
Unsalted butter, at room temperature. Softened butter combines with sugar to trap air and give the cake lift.
Sugar
Eggs, at room temperature
Milk, preferably whole milk for richness; nondairy milk can also be used
White chocolate, use high-quality bars such as Ghirardelli or Baker’s for best results
Semi-sweet chocolate (or bittersweet as an alternative); good-quality chocolate improves flavor and melting performance

Tip: If you like a subtle twist, a 1/4 teaspoon of orange or peppermint extract can be added to the white chocolate batter after dividing the batter.

How to Make This Marble Cake

There are three main stages to this bake: prepare a pound-cake-style batter, flavor and divide it, and create the marble pattern before baking.

Step 1: Make the base batter. Beat the room-temperature butter with sugar until light and fluffy to incorporate air. Add the eggs one at a time, beating until each is incorporated. Alternately add the sifted dry ingredients and the milk in three additions, starting and ending with the flour mixture. Finish by folding briefly with a spatula to avoid overmixing—overbeating will make the cake tough.

Step 2: Infuse the batters with chocolate. Melt the white and semisweet chocolate separately until smooth—using a microwave in 20–30 second bursts or a double boiler works well. Divide the cake batter evenly into two bowls. Fold the melted white chocolate into one portion and the melted semisweet chocolate into the other until just combined and even in color.

Step 3: Create the marble pattern and bake. Grease and flour the pan well. Spoon half of the white chocolate batter into the pan and smooth into an even layer, then add half of the semisweet batter on top. Repeat with the remaining batters in the same order. Use a knife to run through the batter once or twice to create a marble effect—resist the urge to over-swirl or you’ll blend the colors too much. Bake until the center tests done: a toothpick should come out with a few moist crumbs rather than completely dry. Allow the cake to rest 10–15 minutes in the pan before removing to cool completely on a rack.

There are several ways to create the marble look. Dorie Greenspan’s approach is to randomly dollop batters into the pan and then run a knife through once; you can use that or any pattern that produces a clear two-tone interior.

Pan Options

This recipe adapts well to different pans: a 9″x5″ loaf pan, two 8″x4″ loaf pans, or a 9″ bundt pan will all work. Baking times will vary slightly depending on pan size and depth, so check for doneness a few minutes before the recommended time.

Storing the Cake

Store the cooled cake at room temperature in an airtight container or covered on a cake stand for up to 4 days. For longer storage, wrap tightly in foil or plastic wrap, place in a resealable freezer bag, and freeze for up to 2 months. Thaw wrapped at room temperature before serving to preserve moisture.

Important Notes

Use only high-quality chocolate. Lower-quality bars or chips may not melt smoothly and can affect both texture and flavor. The chocolate carries much of the cake’s character, so quality matters.
Do not overbake. Overbaking causes the cake to dry out and makes it stick to the pan. Remove the cake when a toothpick inserted in the center comes out with a few moist crumbs—similar to the test for brownies.

Ingredients

2/3 cup white chocolate, chopped (120 g / 4 oz)
2/3 cup semi-sweet chocolate, chopped (120 g / 4 oz)
2 1/4 cups all-purpose flour (270 g / 10 oz)
1 1/4 tsp baking powder
1/2 tsp salt
1 cup unsalted butter, softened (225 g / 8 oz)
1 cup sugar (200 g / 7 oz)
4 large eggs
1/2 cup milk (120 ml / 4 oz)

Instructions

Preheat the oven to 325°F (160°C). Generously grease the pan and dust with flour, tapping out any excess.
In a medium bowl, sift together the flour, baking powder, and salt; set aside.
Melt the white chocolate in a heatproof bowl, in 20–30 second microwave bursts or over a double boiler, stirring until smooth. Set aside.
Repeat the melting process with the semi-sweet chocolate and set aside.
In the bowl of a stand mixer, cream the butter and sugar on medium-high speed until well combined, about 2 minutes.
Add the eggs one at a time, waiting for each to incorporate fully before adding the next.
Scrape the bowl, then add the flour mixture in three additions alternating with the milk, beginning and ending with the flour. Mix until just combined.
Turn off the mixer and use a rubber spatula to finish incorporating the batter without overmixing.
Divide the batter into two equal portions. Fold the melted white chocolate into one portion and the melted semi-sweet chocolate into the other.
Dollop half of the white chocolate batter into the prepared pan and smooth into an even layer. Add half of the semisweet batter on top. Repeat with the remaining batters.
Run a knife through the batter once or twice to create a marble effect—do not over-swirl.
Bake for about 40 minutes, or until a toothpick inserted into the center comes out with some moist crumbs. Do not overbake.
Remove from the oven and let cool in the pan for 10–15 minutes before unmolding. Cool completely on a wire rack before slicing.
