Nanaimo Bars
A no-bake layered Canadian treat: chocolate-coconut base, custard buttercream middle and chocolate ganache top.
About This Recipe
Nanaimo bars are perhaps the most distinctively Canadian dessert, named after Nanaimo, a city on Vancouver Island in British Columbia. The first printed recipe appeared in the Nanaimo Hospital Auxiliary Cookbook in 1952. These no-bake bars consist of three distinct layers: a dense base of Graham crackers, shredded coconut, cocoa powder and butter; a pale yellow custard buttercream centre made with custard powder; and a thin, glossy chocolate ganache topping. They are served chilled, sliced into small squares or rectangles. The city of Nanaimo held a contest in 1986 to find the definitive recipe.
