"These soft and chewy cookies have no butter, no flour, and no white sugar. Because there's no butter or flour to dilute the flavor, they're intensely peanut buttery. The toffee bits add so much crunchy texture to the otherwise buttery soft and tender dough. The toffee is slightly salty, playing up the salty-and-sweet aspect. There's just a hint of chocolate for flavor, but it doesn't detract from the full-on peanut butter punch these cookies pack. For successful cookies, make sure to really cream the first four ingredients together very well; don't use natural or homemade peanut butter; and it's mandatory the dough is chilled before baking so your cookies don't spread too thin...."
