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

What each ingredient does

Eggs: Whisking whole eggs with sugar traps air, giving the cake lift and a tender, fluffy structure.
All-purpose flour: Its proteins form the gluten network that gives the bars their structure.
Buttermilk: Its acidity reacts with the baking soda to help the bars rise and keeps the crumb tender.
Pumpkin puree: Adds moisture and body, keeping the bars soft and dense.
Light brown sugar: Adds moisture and molasses flavor, and helps the crumb stay soft.
Vegetable oil: Supplies fat that keeps the crumb moist and tender.

The step that matters

Beat the eggs, sugar and egg white until thick and fluffy. Beating air into the eggs and sugar creates foam that gives the batter lift. Under-beating leaves a dense, flat cake, so the batter should look thickened and pale before the dry ingredients go in.
