Kitchen Sink Cookies are soft and chewy cookies packed with chocolate chips, pretzels, potato chips, and toffee ("everything but the…"). Make them as written, or swap in your favorite mix-ins.
My kids still don't totally understand why these are called "Kitchen Sink" Cookies, but they know they love them. When I started testing this recipe, with each batch, the kids said more chocolate chips, more pretzels, more potato chips, more toffee!
