These aren’t your grandma’s cookies. With Colossal Cookies, Wendy Kou, creator of the blog My Dessert Diet, elevates a classic treat with a decadent and supersized approach.

When Kou’s boyfriend tried to limit her cookie intake to one, she found a loophole: make that one cookie equal to the size of ten. Since then, Kou has been baking treats big enough to share with a crowd. Think the size of a single layer cake but with the chewy consistency of a soft cookie. These massive cookies are a fresh and accessible approach to desserts made for sharing, with the same wow-factor as cakes but none of the pressure.

Having friends over for a movie night? Indulge in sinfully satisfying recipes like the colossal double chocolate chip cookie stuffed with marshmallow or the red velvet cookie with white chocolate chunks. Hosting a luncheon or shower? Keep things lighter with raspberry rose or lemon apricot cookies. Or bake a couple for your kid’s soccer team and see how quickly you become the favorite parent. And if you’re short on time, Kou includes a section of recipes that rely on boxed mixes, making it even easier to whip up a confection large enough to feed a family.

Replete with techniques, tips, and equipment lists, Colossal Cookies has everything you need to up your cookie game.
