A 7 layer bar recipe is a dessert recipe that typically consists of seven layers, beginning with a graham cracker crust, followed by layers of coconut, pecans, sweetened condensed milk, butterscotch or chocolate chips, peanuts, and chocolate ganache.
Originating in the 1950s, 7 layer bars gained popularity throughout the following decades and remain a beloved dessert due to their ease of preparation, affordability, and crowd-pleasing flavor profile. They are commonly served at gatherings and celebrations and have become a staple of American home cooking.
