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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the 3 eggs 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.
Flavor with vanilla and fold in the grated chocolate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb.
- Eggs
- Add structure and richness as they set during baking.
- Flour
- Forms the cake's structure once its proteins set in the oven.
- Baking powder
- Releases gas during baking so the cake rises and becomes airy.
- Sugar
- Sweetens the cake and helps it brown and stay tender.
- Egg whites
- Whipped to stiff peaks to form a light, stable frosting.
The step that matters
Beat the egg whites to stiff peaks. Egg whites must be free of any fat or yolk to whip fully. Adding sugar gradually keeps the foam stable and glossy, so the frosting holds its shape.
