Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

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.
Prepare the batter
Beat the eggs in a bowl.
Fill a cup with cold water and melted butter, alternating 1 tablespoon of each until full.
In a mixing bowl, combine the sugar, flour, and baking powder.
Add the egg mixture to the dry ingredients and mix well.
Bake and assemble
Bake in layers at 350°F (175°C) until golden.
Spread frosting on each layer and top with sliced bananas.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Bind the batter and add structure and moisture as they set in the oven.
- Flour
- Provides the main structure that holds the cake's crumb together as it bakes.
- Sugar
- Adds sweetness and helps the crust brown as it bakes.
- Baking powder
- Releases gas in the batter so the layers rise and become light.
- Melted butter
- Adds fat that tenderizes the crumb and carries flavor.
- Bananas
- Add sweetness, moisture, and fruity aroma to the finished layers.
The step that matters
Mix the batter gently after adding the eggs. Once the wet and dry ingredients combine, stirring too much develops gluten in the flour, which can make the cake tough and dense instead of tender.
Swap the banana
How well each one fits the dish's main ingredients (egg, butter, sugar, flour):
- Raisinfits better
- Vanillafits better
- Figfits better
- Bananathe original
Fit is the average pairing score against egg, butter, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
