These seven-layer bars, a.k.a. magic bars, are the ideal gateway dessert recipe for nonbakers. They only take one pan and require no mixing of ingredients. Just melt butter in a 13-by-9-inch baking dish, sprinkle it with crushed graham crackers, and layer on the coconut, chocolate chips, and nuts. Sweetened condensed milk binds it all together while it bakes, and after about an hour, you’ll have a dessert that was just as easy as any prepackaged mix, but is way tastier.
