Nanaimo Bar
“Three-layer no-bake confection from Nanaimo, British Columbia — bottom layer of cocoa-coconut-graham-cracker crumb, middle layer of pale yellow custard-flavored butter cream, top layer of melted dark chocolate. Cut into squares and served at every BC bake sale, every potluck, every wedding cookie tray.”
Where it comes from
First published recipe in 1953 in the Nanaimo Hospital Cookbook submitted by Mabel Jenkins, but variants appeared in BC women's magazines since the 1940s. The exact origin is disputed but the name 'Nanaimo Bar' became canonical by the 1980s. Custard powder (Bird's brand) in the middle layer is the British-colonial inheritance that locks the bar's identity.
On the plate
Fork knocks into thin cap of dark chocolate — it cracks crisp like a glaze. Then the soft yellow custard cream, almost playdough-soft, with vanilla-and-custard sweetness. Bottom layer is denser, with cocoa darkness and the textural contrast of coconut shred and walnut crunch. Three distinct textures, three distinct sweetness levels, one tidy square. The reason it's the BC potluck standard.
How it works
Custard powder (Bird's brand specifically — cornstarch + vanilla + yellow coloring + salt) is the structural component of the middle layer — without it, the butter cream is just buttercream. The custard powder absorbs liquid and gives the layer its characteristic playdough body. The hot-knife scoring before final set is critical: chocolate cools faster at thinner cuts, preventing the brittle top from cracking irregularly.
Variations
Mint Nanaimo (with peppermint extract in the middle layer and white chocolate on top) is a Vancouver innovation. The peanut-butter version replaces some butter in the middle with peanut butter. The Nanaimo-Tourism-Board-defined 'classic' specifies Bird's custard powder; substituting vanilla pudding is heresy locally.

Bottom layer: melt 125 g butter + ¼ cup sugar + 5 tbsp cocoa powder + 1 beaten egg in a double boiler, stirring constantly until thickened (3-4 min).
- 23 min
Off heat, mix in 1 cup graham-cracker crumbs + 1 cup desiccated coconut + ½ cup chopped walnuts.
- 332 min
Press firmly into a 23×23 cm parchment-lined pan. Refrigerate 30 min.

Middle layer: cream 125 g softened butter + 3 cups powdered sugar + 3 tbsp custard powder (Bird's) + 3 tbsp heavy cream + 1 tsp vanilla. Beat 5 min until light and fluffy.
- 532 min
Spread evenly over bottom layer. Refrigerate 30 min.
- 64 min
Top layer: melt 175 g dark chocolate + 30 g butter in double boiler until smooth.
- 75 min
Pour over middle layer; tilt pan to coat evenly. Score lines for 16 squares while chocolate is still soft (using a hot knife) — this prevents cracking later.

Refrigerate 2 hours. Cut along score lines with a hot knife. Store refrigerated.
