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 cake
Preheat oven to 350°F (175°C).
Cream sugar and butter until light and fluffy.
Add vanilla and milk, mixing well.
Gradually stir in flour and baking powder until combined.
Fold in beaten egg whites gently until just incorporated.
Pour batter into greased cake pan.
Bake for 25-30 minutes or until a toothpick comes out clean.
Make the icing
Combine sugar, milk, and butter in a saucepan.
Boil mixture until it reaches a waxy consistency.
Remove from heat.
Stir in vanilla.
Beat until stiff.
Assemble
Spread melted chocolate on the bottom and top of the layers.
Use cream icing between the layers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air in the batter, giving the cake lift and a light crumb.
- All-purpose flour
- Its proteins set during baking, forming the cake's structure.
- Baking powder
- Releases gas when heated, helping the cake rise.
- Butter
- Creaming with sugar traps air and adds richness and tender texture.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
The step that matters
Boiling the icing to a waxy consistency. Sugar syrup must reach the right concentration; too little boiling leaves the icing runny, while overboiling makes it hard and grainy. Removing it from heat at the right moment sets the texture.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, butter, vanilla, milk, flour, egg, chocolate):
- Almondfits better
- Hazelnutfits better
- Chestnutfits better
- Walnutthe original
Fit is the average pairing score against sugar, butter, vanilla, milk, flour, egg, chocolate. Candidates are from the same food group and used in at least 100 recipes.
