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 Cake II
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.
Make the custard
Combine 1 cup brown sugar, ½ cup grated chocolate, and ½ cup sweet milk in a saucepan.
Boil until thickened like custard.
Make the batter and bake
Once cooled, mix in 1 teaspoon vanilla, 1 cup brown sugar, ½ cup softened butter, ½ cup sweet milk, 3 eggs, 2 cups all-purpose flour, and 1 teaspoon baking soda.
Divide the batter into two layers and bake at 350°F (175°C) until done.
Make the filling and assemble
For the filling, melt 3 ounces chocolate in a double boiler.
Stir in ½ cup milk and ½ cup sugar until smooth.
Add the yolk of 1 egg and 1 teaspoon vanilla to the chocolate mixture, cool, and spread between the cake layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the main structure that holds the cake's crumb together as it bakes.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Baking soda
- Reacts with the batter's acidity to produce gas that helps the cake rise.
- Butter
- Adds fat that tenderizes the crumb and gives a richer mouthfeel.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown and stay tender.
- Chocolate
- Provides the main chocolate flavor and deep color in the cake and filling.
The step that matters
Adding the egg yolk to the filling. If the chocolate mixture is still hot, the yolk can scramble and turn grainy. Letting it cool first keeps the filling smooth and evenly thickened.
