Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Banana 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.
Make the batter
Cream the butter and sugar together.
Beat the egg whites to a stiff froth.
Combine the flour, milk, and baking powder with the creamed mixture.
Bake and assemble
Bake in layers at 350°F (175°C).
Make a plain frosting and spread it between the layers.
Slice bananas thin and spread them over the frosting so that each slice touches the other.
Finish the cake with a plain frosting.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Whipped whites add lightness and help the cake rise and hold its structure.
- Flour
- Forms the structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking so the layers rise and become light.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Bananas
- Add moisture and banana flavour to the layers.
The step that matters
Beat the egg whites to a stiff froth. Whites under-beaten stay loose and deflate in the batter, while over-beaten whites turn dry and grainy. Stiff, glossy peaks trap air that lifts the cake and keeps it light.
Swap the banana
How well each one fits the dish's main ingredients (sugar, butter, egg, flour, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Bananathe original
Fit is the average pairing score against sugar, butter, egg, flour, milk. Candidates are from the same food group and used in at least 100 recipes.
