Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour: Provides the main structure that holds the cake's crumb together.
Baking powder: Releases gas during baking so the cake rises and becomes light.
Baking soda: Reacts with the acidic buttermilk and bananas to help the cake rise and brown.
Mashed ripe bananas: Add moisture, sweetness, and banana flavor to the crumb.
Eggs: Add structure and richness, helping bind the batter as it sets.
Buttermilk: Adds acidity that tenderises the crumb and activates the baking soda.

The step that matters

Beat on medium speed for 2 minutes, then add the eggs and beat for 1 minute. Beating after the flour is added develops gluten, which gives structure. Overbeating makes the cake tough and dense, so beat only for the stated times.
