Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Chocolate Layer 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.

Prepare

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

Make the batter

  1. In a bowl, cream the butter and gradually add the sugar.

  2. Beat in the milk and vanilla extract.

  3. Add the eggs, mixing well after each addition.

  4. Stir in the grated chocolate.

  5. In a separate bowl, mix the flour with the baking powder, then gradually add to the wet mixture.

  6. Pour the batter into two well-buttered shallow cake pans.

Bake and finish

  1. Bake for 25 minutes or until a toothpick comes out clean.

  2. Ice the cake if desired.

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

What each ingredient does

Eggs
Bind the batter and add structure as they set during baking.
Flour
Provides the structure that holds the cake's crumb together.
Butter
Adds richness and tenderness through fat coating the flour.
Sugar
Sweetens the cake and helps keep it moist and tender.
Baking powder
Releases gas in the batter so the cake rises in the oven.
Chocolate
Adds chocolate flavor and deep color to the batter.

The step that matters

Adding the flour and baking powder. Mixing the flour gently and only until combined keeps the crumb tender, because overworking flour develops gluten and makes the cake tough.
