Marbled Cake

Oven, in the book's wordsA steady oven

Ingredients

Directions

The book says “a steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the batter

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

  2. In a bowl, cream the butter and powdered sugar until light and fluffy.

  3. Add the eggs one at a time, mixing well after each addition.

  4. Sift the flour and baking powder together, then gradually add to the mixture.

Make the chocolate swirl

  1. Reserve 2 tablespoons of milk to mix with the grated chocolate.

  2. In a separate bowl, combine the reserved milk with the chocolate.

  3. Take 3 tablespoons of the batter and mix it with the chocolate mixture.

Assemble and bake

  1. Grease a cake mold and fill it one-third full with the plain batter.

  2. Drop spoonfuls of the chocolate mixture on top and swirl slightly.

  3. Add more batter and repeat the process until the mold is filled.

  4. Bake for 45 minutes or until a toothpick inserted 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 sugar to trap air, giving the cake a light, tender crumb.
Eggs
Add structure and richness, binding the batter as the cake sets.
Flour
Forms the main structure that holds the cake together as it bakes.
Baking powder
Releases gas during baking, helping the cake rise and become airy.
Grated chocolate
Gives the dark swirls a rich, bittersweet flavor and contrast in color.

The step that matters

Swirl the chocolate lightly. Over-swirling blends the chocolate fully into the batter, losing the marbled pattern. A gentle swirl keeps distinct streaks that remain visible after baking.
