Cookies with a Deep, Dark Chocolaty Secret
Chocolate chip cookies can handle a pretty dazzling array of mix-ins, from pretzels to cornflakes to chili flakes and even ground coffee. But how about inserting an entire brownie inside the cookie dough, so it's completely hidden until you take a bite? It can be done—and, in fact, doing so is surprisingly easy. Just make a batch of chocolate chip cookie dough, portion it into balls on a baking sheet, gently flatten each one a bit and place half of a store-bought brownie bite in the middle. Roll the dough around the brownie until the cookie dough is round again and bake. When they're cool, bite into one and be amazed.
