How to Make It
Preheat oven to 350°F and line two baking sheets with parchment paper.
Beat butter on medium speed until smooth and creamy. Add both sugars and mix until fluffy. Add eggs and vanilla; mix well.
Next, add flour, baking soda, and salt. Mix until all ingredients are incorporated. Form balls with about 2 tbsp of dough. Place about 2 inches apart on prepared baking sheets.
Bake at 350°F until lightly browned on bottom and around edges, 10 to 12 minutes, rotating pans halfway through. Cool on baking sheet 2 minutes. Transfer to a wire rack, and cool completely (about 30 minutes).
