Why it works: Banana and vanilla 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 Cream Cake No. 1
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 cake
Cream the sugar and butter together.
Add unbeaten egg yolks and beat until light.
Sift the flour, salt, and baking powder together three times.
Add alternately to the creamed mixture with the cold water.
Add the extract, then beat the mixture for one minute before folding in the stiffly beaten egg whites.
Bake in a greased and flour-dusted layer pan at 350°F (175°C) until done.
Assemble
Once baked, cool the cake and split it into layers.
Crush the bananas with ⅓ cup sugar and place between the layers.
Make the icing
For the icing, beat the egg lightly and add the milk.
Mix the sugar, flour, and salt together, then add to the milk and egg mixture.
Cook in a double boiler until thick, stirring constantly.
Remove from heat, add butter and vanilla, and spread over the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the cake and thickens the icing as it cooks.
- Eggs
- Egg whites add lift and airiness, while yolks enrich the batter and help bind it.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Sugar
- Sweetens the cake and helps keep its crumb tender and moist.
- Bananas
- Add moisture and banana flavor between the layers.
The step that matters
Cook the icing in a double boiler, stirring constantly. The egg and flour mixture thickens as it heats and can curdle, lump, or scorch if it gets too hot. Gentle heat and constant stirring keep it smooth and evenly thick.
Swap the banana
