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
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).
Cream the butter and sugar together until light and fluffy.
Add the eggs, reserving 2 egg whites, and mix well.
Stir in the milk and baking powder.
Gradually add the sifted flour and mix until smooth.
Pour the batter into two long baking tins.
Bake and frost
Bake for about 30-35 minutes or until a toothpick comes out clean.
Let the cake cool completely before frosting.
For the frosting, beat the reserved egg whites to stiff peaks. Gradually add 1½ cups sugar while continuing to beat. Mix in the grated chocolate and vanilla.

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 and gives the cake a tender, rich crumb.
- Eggs
- Provide structure and moisture, and help bind the batter as it sets.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Sugar
- Sweetens the cake and helps create a light, fluffy creamed base.
- Egg whites
- Whipped to stiff peaks, they give the frosting its airy, light texture.
The step that matters
Cooling completely before frosting. Frosting a warm cake melts the sugar and chocolate, causing the topping to slide off or turn greasy and soft. Full cooling lets the crumb firm up so the frosting stays put.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
