Marble Chocolate Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batters

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, cream together 1 cup sugar and ½ cup butter for the light part.

  3. Add 3 egg whites, 1 cup milk, 1 teaspoon baking powder, and about 2 cups flour. Mix well.

  4. In another bowl, cream together 1 cup sugar and ½ cup butter for the dark part.

  5. Add 3 egg yolks, 1 cup milk, ¾ cup grated chocolate, 1 teaspoon baking powder, and about 2 cups flour. Mix well and flavor with vanilla.

Marble and bake

  1. In a round deep pan, alternate spoonfuls of the light and dark batter.

  2. Bake until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Creams with the sugar to trap air, giving the cake a tender, rich crumb.
Egg whites
Whip-free structure from the light batter, helping the cake set and rise.
Egg yolks
Add richness and fat to the dark batter, softening the crumb.
Flour
Provides the structure that sets as the cake bakes.
Baking powder
Releases gas in the batter, helping the cake rise.
Grated chocolate
Adds chocolate flavor and color to the dark batter.

The step that matters

Alternating the light and dark batters. Spooning the two batters in loose layers, rather than stirring them, creates the marbled pattern. Overmixing blends them into an even brown cake, and the batters should be spooned, not poured, to keep the swirl distinct.
