Why it works: Vanilla and banana are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,430 recipes. Both carry ethyl isobutyrate, which smells fruity, ethereal. 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. 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a bowl, mix baking soda and cream of tartar.
In another bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Gradually add the flour and milk, mixing until smooth.
Bake and make the cream
Pour the batter into prepared cake pans and bake for 25-30 minutes.
Whip the rich cream until light and fluffy, then flavor with sugar and vanilla.
Assemble
Once the cakes are cool, slice them into layers.
Layer the cake with sliced bananas and whipped cream, repeating until all layers are used.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Add structure and richness as they are beaten into the creamed butter and sugar.
- Baking soda
- Reacts with the acid in the cream of tartar to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda, supporting rise and a tender crumb.
- Flour
- Forms the structure of the cake once it sets in the oven.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a lighter texture.
- Sugar
- Sweetens the cake and helps it brown while creaming with butter adds air.
The step that matters
Creaming the butter and sugar until light and fluffy. Beating air into the butter and sugar creates bubbles that help the cake rise and give it a light texture. Under-creaming leaves a dense cake, while the eggs should be added one at a time so the mixture stays emulsified.
