Shauna Sever's Chocolate Chip CookieBrittle

"This chocolate chip cookie variant should get its own special bookmark in your brain right now, for the next time you need a last-minute party snack or cookie swap entry or a gift for pretty much anyone (including yourself). Conveniently, the brittle packs up well in a big jar for holidays, birthdays, and sugar-fueled road trips and plane rides. It's also quite friendly to swap-ins for the nuts and chocolate—coconut? chile? pretzels?—if you need a place to set yourself free.
