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 cake
Preheat the oven to 350°F (175°C).
Cream together the butter and sugar until light and fluffy.
Add the milk and mix well.
In a separate bowl, combine the flour, corn starch, and baking powder.
Gradually add the dry ingredients to the wet mixture, mixing until smooth.
Fold in the egg whites gently until fully incorporated.
Pour the batter into a long shallow pan.
Bake for about 30‑35 minutes or until a toothpick comes out clean.
Make the frosting
For the frosting, combine ½ cup milk, butter, brown sugar, and chocolate in a saucepan.
Cook over medium heat until thickened.
Remove from heat.
Stir in the vanilla.
Finish and set
Spread the frosting on the cooled cake.
Return to the oven for a few minutes until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and helps give the cake a tender crumb when creamed with sugar.
- Sugar
- Sweetens the cake and, creamed with butter, traps air that helps it rise and become light.
- Flour
- Provides the main structure that sets as the cake bakes.
- Egg whites
- Add structure and lift, helping the batter rise and set in the oven.
- Baking powder
- Releases gas in the batter so the cake rises.
- Chocolate
- Gives the frosting its chocolate flavor and body as it thickens.
The step that matters
Fold in the egg whites gently. Egg whites hold air that gives the cake its lift. Stirring hard knocks that air out, so the cake bakes up dense instead of light.
