Chocolate Cake

Oven, in the book's wordsA rather slow oven

Ingredients

Directions

The book says “a rather slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Boil the grated chocolate, milk, and egg yolk until thick.

  2. Let the mixture cool, then stir in the sugar, softened butter, sweet milk, flour, and dissolved baking soda.

  3. Add vanilla extract to taste.

Bake

  1. Pour the batter into a greased baking pan.

  2. Bake in a slow oven at 300°F (150°C) until a toothpick comes out clean.

  3. This can be made into a layer or loaf cake.

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

What each ingredient does

Grated chocolate
Provides the chocolate flavor and deep color of the cake.
Egg yolk
Helps thicken the chocolate mixture and adds richness to the batter.
Butter
Adds fat for a tender crumb and rich flavor.
Flour
Provides the structure that holds the cake together as it bakes.
Baking soda
Reacts with the batter to help it rise and lighten the crumb.
Sugar
Sweetens the cake and helps keep it moist and tender.

The step that matters

Boiling the chocolate, milk, and egg yolk until thick. The mixture must thicken fully before cooling, because the egg yolk sets with heat and gives body to the chocolate base. Undercooked yolk stays thin and can weaken the batter's texture.
