Rest dough. Allow the dough to rest for 15-20 minutes while you prep your baking sheet to hold the scooped cookie dough balls. They will sit on the baking sheet in the fridge as they chill overnight.
Prep pan + scoop dough. Line a pan with parchment paper. Scoop your dough using a 2 TBSP cookie scoop and begin placing the cookie dough balls on the pan. Fill the entire pan, as you will be resting the dough and don’t need to worry about spacing yet. 30 cookies will fit comfortably on a half-sheet pan or a jellyroll pan.
Cover + chill. Cover the pan with plastic wrap and place in the fridge to chill for 8-12 hours, or overnight.
Preheat oven. Heat the oven to 350ºF. Keep the cookies in the fridge as you bake batches, so they stay as cold as possible between batches.
Place cookies on pan. Space the cookies 2-2.5 inches apart on a cookie sheet lined with parchment paper. 8 cookies fit well on a half-sheet pan, staggering the cookies in lines of 2, then 1, as pictured in the instructions of the blog post.
Bake in batches. Bake for 10 - 12 minutes, or just until the edges and tops of the cookies start to brown lightly.
Cool. Allow the cookies to cool on the baking sheet for 2 minutes. This helps them to finish baking! After 2 minutes, move them to a cooling rack.
Store. Store your finished cookies in an airtight storage container for up to 5 days.
