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

What each ingredient does

Cream cheese: Provides the rich, dense body that sets into a creamy filling.
Eggs: Set the filling into a firm, sliceable custard as it bakes.
Sour cream: Adds moisture and tang, keeping the filling smooth and tender.
Vanilla wafers: Form the crumbly base that holds the bars together.
Granulated sugar: Sweetens the filling and helps it stay smooth.
Unbleached flour: Adds a little structure to help the filling hold its shape.

The step that matters

Cool and refrigerate for hours. Eggs in the filling need to cool fully to set. Cutting or serving too early can leave the bars soft and make them crumble.

Swap the pecans

How well each one fits the dish's main ingredients (vanilla, butter, cream cheese, sugar, cream, flour, egg):
