- Unsalted Butter: Use room temperature butter for this recipe.
- Granulated Sugar: Use regular granulated white sugar.

Why Use Room Temperature Ingredients?
Using room temperature ingredients is an important part of making perfect cookies! Room temperature butter allows it to properly emulsify with the sugars. Using butter that is too cold or too warm will lead to cookies that are not light and airy.Â
