The Nanaimo bar // is a dessert item of Canadian origin. It is a bar dessert which requires no baking and is named after the city of Nanaimo, British Columbia, on Vancouver Island. It consists of three layers: a wafer and coconut crumb-base, custard flavoured butter icing in the middle and a layer of chocolate ganache on top. Many varieties exist, consisting of different types of crumb, different flavours of icing (e.g., mint, peanut butter, coconut, mocha), and different types of chocolate.
The earliest confirmed printed copy of the recipe using the name "Nanaimo bars" appears in the Edith Adams' prize cookbook (14th edition) from 1953. A copy of the book is on view at the Nanaimo Museum. However, following research into the origins of Nanaimo bars, Lenore Newman writes that the same recipe was published in the Vancouver Sun earlier that same year under the name "London Fog Bar". The recipe later also appears in a publication entitled His/Her Favourite Recipes, Compiled by the Women's Association of the Brechin United Church (1957), with the recipe submitted by Joy Wilgress, a Baltimore, Maryland, native. (Brechin United Church is in Nanaimo.)
In 1954 the recipe "Mabel's Squares" was published in The Country Woman's Favorite by the Upper Gloucester Women's Institute (New Brunswick). The recipe was submitted by Mrs. Harold Payne, the daughter of Mabel (Knowles) Scott (1883-1957). The ingredients list, quantities, and fabrication closely match the recipe found on the City of Nanaimo's website.
The first printing of recipes featuring Nanaimo bar ingredients is found in the 1952 Women's Auxiliary to the Nanaimo Hospital Cookbook, which features three nearly identical recipes that differ only slightly from the modern Nanaimo bar. They are referred to as the "chocolate square" or the "chocolate slice".
Other unconfirmed references date the bar back to the 1930s, when it was said to be known locally as "chocolate fridge cake". One modern reference even refers to the bars' existing in nineteenth century Nanaimo.
The popularity of the bar in Nanaimo led local residents to mobilise to have it voted "Canada's Favourite Confection" in a National Post reader survey. In 1985, Mayor Graeme Roberts initiated a contest to find the ultimate Nanaimo bar recipe. The recipe submitted by Joyce Hardcastle, a resident of Nanaimo, was unanimously selected by a panel of judges.
Recipes for similar desserts are found in various places, under various names, in North America and Europe. The designation "Nanaimo bar" is Canadian, and appears in the Canadian Oxford Dictionary, but not in other language or dialect versions.
The 2016 US state dinner in honour of Justin Trudeau featured Nanaimo bars. The elaborate dinner hosted by former US President Barack Obama and his wife Michelle Obama consisted of a blend of American and Canadian dishes. The main dessert featured was Nanaimo bars, and was presented on a plate inspired by the Rocky Mountains. 
In April 2019, Canada Post announced the release of a booklet of postage stamps dedicated to Canadian desserts and sweets. The booklet of 10 stamps features images of the Nanaimo bar, the butter tart, tarte au sucre (sugar pie), blueberry grunt, and Saskatoon berry pie. Canada Post described the stamps as "fun-shaped" and appear on a recipe card background. The Nanaimo bar stamp received some criticism for its ratio of "the crumbly base, the custard filling, and the chocolate ganache icing."
