Chocolate Marble 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the batter

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

  2. In a bowl, cream together the sugar and butter.

  3. Add the egg and sweet milk, mixing well.

  4. In a separate bowl, combine the flour, baking soda, and cream of tartar.

  5. Gradually add the dry ingredients to the wet mixture, stirring until smooth.

  6. Divide the batter in half.

  7. To one half, add the grated chocolate and mix well.

Marble and bake

  1. Pour the two batters into a greased cake pan.

  2. Swirl the batters together to create a marbled effect.

  3. Bake for 30-35 minutes or 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

Flour
Provides the structure that holds the cake together as it bakes.
Butter
Adds fat for a tender crumb and rich flavor.
Sugar
Sweetens the cake and helps it brown while tenderizing the crumb.
Egg
Binds the batter and adds structure and richness.
Baking soda
Reacts with the acid in the batter to produce gas that helps the cake rise.
Cream of tartar
Acidifies the batter, activating the baking soda and stabilizing the texture.
Grated chocolate
Adds the dark marbled streaks and a deep chocolate flavor.

The step that matters

Swirling the batters. Swirling too much blends the two batters into an even color and loses the marble pattern, while swirling too little leaves uneven pockets. A few gentle turns keep distinct streaks without deflating the rising batter.
