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
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the cornstarch, baking powder, and milk, mixing until smooth.
Bake and assemble
Divide the batter into two layers and bake until golden.
While warm, place sliced bananas between the layers.
Ice the cake.
Serve fresh.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that makes the crumb tender and rich in flavor.
- Sugar
- Sweetens the cake and, when creamed, traps air that helps it rise and lighten.
- Cornstarch
- Softens the crumb by diluting gluten, giving a finer, more tender texture.
- Baking powder
- Releases gas in the batter so the layers rise and set light.
- Milk
- Adds moisture and hydrates the starches so the batter flows and bakes evenly.
- Sliced bananas
- Add natural sweetness, moisture, and banana aroma between the layers.
The step that matters
Cream the butter and sugar until light and fluffy. Beating sugar into butter creates tiny air pockets that expand in the oven. Stopping early leaves a denser cake with less lift.
Swap the banana
How well each one fits the dish's main ingredients (butter, sugar, milk):
- Vanillafits better
- Figfits better
- Peachfits about as well
- Bananathe original
Fit is the average pairing score against butter, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
