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

What each ingredient does

Sugar: Adds sweetness and helps the cookies brown as they bake.
Flour: Provides the structure that holds the cookie dough together as it bakes.
Eggs: Bind the dough and add structure and richness.
Butter: Adds fat, which gives the cookies tenderness and rich flavor.
Baking powder: Releases gas as it reacts in the batter, helping the cookies rise.
Chocolate: Adds deep chocolate flavor and some fat to the dough.
