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

What each ingredient does

Peanut butter: Provides fat and rich peanut flavor, and keeps the cookies tender.
Butter: Adds fat for richness and helps the cookies spread and brown.
Sugar: Adds sweetness and helps the cookies brown and crisp at the edges.
Light brown sugar: Adds sweetness and moisture, giving a softer, chewier texture.
Egg: Binds the dough and adds structure as the cookies set.
All purpose flour: Provides the structure that holds the cookies together as they bake.
