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.

Prepare the batter

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

  2. In a large bowl, beat the egg whites until stiff.

  3. In another bowl, cream the butter and sugar together.

  4. Gradually add the flour, cornstarch, milk, and baking powder to the butter mixture.

  5. Take out 1 cup of the batter and mix in the grated chocolate moistened with a little milk.

Assemble and bake

  1. Pour a layer of the white batter into a greased pan.

  2. Drop spoonfuls of the chocolate batter onto the white batter.

  3. Spread the remaining white batter over the chocolate spots.

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

What each ingredient does

Egg whites
Beaten until stiff, they trap air and give the cake a light, open structure.
Butter
Creamed with sugar, it adds richness and tenderness to the crumb.
Sugar
Creamed with butter, it sweetens the cake and helps give a tender texture.
Flour
Provides the main structure of the cake once baked.
Cornstarch
Softens the crumb, making the cake more tender than flour alone would.
Baking powder
Releases gas during baking so the cake rises and becomes light.

The step that matters

Spreading the remaining white batter over the chocolate spots. Spoon the chocolate batter gently and spread the white batter carefully so the layers stay distinct; heavy mixing blends the colours into an even brown and loses the marbled pattern.
