Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to give the cookies richness and a tender crumb.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown during baking.
- Rolled oats
- Provide chewy texture and bulk to the dough.
- Flour
- Gives the dough structure so the cookies hold their cut shape.
- Baking powder
- Releases gas in the oven so the cookies rise and lighten.
The step that matters
Chill the dough thoroughly. Chilling firms the butter so the dough holds its shape when rolled and cut. Warm, soft dough spreads too much in the oven and bakes flat and greasy.
