Ingredients
Method
Place a rack in middle of oven; preheat to 300°. Pulse brown sugar and powdered sugar in a food processor to combine. Add butter and pulse just until combined. Add einkorn flour, all-purpose flour, and salt and pulse until dough comes together. Turn out onto a clean surface; press into about a 6"-diameter disk.
Place dough between 2 sheets of parchment paper and roll out to a ⅓"–½"-thick round. Remove top sheet of parchment and punch out cookies with larger cutter. If using smaller cutter, punch out center of each cookie. Carefully transfer cookies to a large parchment-lined baking sheet, spacing 1" apart. Reroll scraps; punch out more cookies.
Bake cookies, rotating baking sheet front to back halfway through if browning unevenly, until golden and firm around edges, 25–35 minutes. Let cool on baking sheet. Do ahead: Cookies can be baked 2 days ahead. Store airtight at room temperature.
