These no-bake, three layered snack bars start with a crumb base, followed by a layer of light custard buttercream, then topped with a shimmering layer of chocolate. Nanaimo Bars are one of Canada's favorite confections, named after the beautiful city of Nanaimo, B.C. It all began when Mabel Jenkins, a Nanaimo housewife entered the recipe in a magazine contest back in the 1950's. She won the contest with these tasty treats even made the town famous for them. There are six variations of filling here at the bottom of this recipe. Buddha got this recipe from a co-worker named Kindalee.
