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

What each ingredient does

Flour: Provides the structure that holds the bars together as the batter sets.
Butter: Adds richness and tenderness through fat creamed with the sugar.
Brown sugar: Adds sweetness, moisture and a caramel-like depth of flavor.
Eggs: Bind the batter and help set the crumb as it bakes.
Sour cream: Adds moisture and tang, keeping the crumb tender.
Baking powder: Releases gas during baking so the bars rise and stay light.

The step that matters

Beating the flour mixture in alternately with sour cream. Adding flour in portions alternating with the sour cream keeps the batter smooth and evenly hydrated. Overmixing once flour is in develops gluten, which can make the bars tough.

Swap the white pepper
