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

What each ingredient does

Eggs: Bind the dough and add structure, moisture and richness as they set in the oven.
Sugar: Adds sweetness and, when creamed with butter, helps give a tender crumb.
Butter: Adds fat for richness and tenderness, and carries flavor through the dough.

The step that matters

Cream butter and sugar. Creaming beats air into the butter while the sugar's crystals cut into it. This trapped air helps the cookies rise and keeps them tender, so beat until light and fluffy.
