Why it works: Vanilla and milk 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
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
Beat the butter until creamy, then add the sugar and mix well.
In a separate bowl, combine the cream and egg whites, then add to the butter mixture.
Sift the flour with the baking powder and gradually add to the mixture, stirring until smooth.
Add vanilla extract to taste and mix well.
Bake and ice
Pour the batter into a greased cake pan and bake for 30-35 minutes or until a toothpick comes out clean.
For the icing, mix the confectioner's sugar, milk, and vanilla until smooth.
Spread a heavy layer of icing on the cooled cake.
For a second layer, mix another batch of icing with the melted chocolate and spread it on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creaming with sugar traps air, giving the cake a tender, light crumb.
- Egg whites
- Provide structure and lift as they set in the oven, helping the cake rise.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas when heated, helping the batter rise in the oven.
- Sugar
- Sweetens the cake and helps keep it moist and tender.
- Melted chocolate
- Adds rich chocolate flavor and color to the second icing layer.
The step that matters
Baking the batter. Batter with baking powder must go into the oven promptly after mixing, since the gas-releasing reaction starts once wet and dry ingredients combine. Baking to a clean toothpick test ensures the structure is set so the cake does not collapse or stay gummy in the center.
