Marbled Chocolate Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; 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. Cream the butter and sugar together until light and fluffy.

  3. Add the eggs and milk, mixing well.

  4. Sift in the flour and baking powder, and combine until smooth.

  5. Take out 1 cup of the batter and mix it with the dissolved chocolate.

Layer and bake

  1. In a greased pan, pour a layer of the white batter.

  2. Drop spoonfuls of the chocolate batter on top to form rings.

  3. Repeat layering with the remaining batters until all is used.

  4. Bake for 30-40 minutes or until a toothpick comes out clean.

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

What each ingredient does

Butter
Adds fat and richness, and creaming it with sugar traps air for a tender crumb.
Sugar
Sweetens the cake and helps create a light, fluffy texture when creamed.
Eggs
Provide structure as they set, and add richness and moisture to the batter.
Flour
Forms the main structure of the cake as its proteins set during baking.
Baking powder
Releases gas in the batter to help the cake rise.
Chocolate
Gives the darker batter its flavor and the marbled pattern.

The step that matters

Layering the batters. Pouring the batters gently keeps the layers distinct; stirring or heavy pouring blends the chocolate into the white batter and blurs the marbling.
