Makes about 2 dozen sandwich cookies.
Note: Adapted from "The Back in the Day Bakery Cookbook," by Cheryl Day and Griffith Day. "I was always the queen of sales during during Girl Scout cookie season," writes Cheryl Day. "My dad would take me to the back lot of Desilu Studios, where he worked, and I would go to town writing up orders. As it is for so many other people, my favorite Girl Scout cookie is the Thin Mint. Here's a grown-up version."
For cookies:
• 23/4 c. flour
• 11/4 c. Dutch-process unsweetened cocoa powder
• 1/2 tsp. fine sea salt
• 1 c. (2 sticks) unsalted butter, at room temperature
