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 ↓
Whipped Cream Banana Cake
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 400°F (200°C).
Cream the butter and sugar together.
Add the milk, then mix in the flour and baking powder.
Fold in the beaten egg whites.
Pour the batter into a cake pan and bake for 15 minutes.
Assemble and serve
Once cooled, layer sliced bananas on the cake and top with whipped cream.
Repeat with another layer of bananas and whipped cream on top.

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 tender, rich crumb and fat for flavor.
- Eggs
- Whites are beaten and folded in to add lift and structure to the batter.
- Baking powder
- Releases gas in the batter during baking, helping the cake rise and become light.
- Flour
- Forms the structure of the cake as its proteins set in the oven.
- Milk
- Adds moisture to the batter and helps it come together smoothly.
- Bananas
- Add sweetness, moisture and fruity aroma to the layers.
The step that matters
Folding in the beaten egg whites. Egg whites hold air bubbles that give the cake its lift. Stirring them in vigorously or too long deflates the foam, leaving a dense cake, so fold gently until just combined.
Swap the banana
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg, cream):
- Vanillafits better
- Raisinfits better
- Coconutfits about as well
- Bananathe original
Fit is the average pairing score against sugar, butter, milk, flour, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
