Canadian Nanaimo Bars

Nanaimo bars are a Canadian icon, named after the city of Nanaimo on Vancouver Island. Three layers, no baking, and a flavor combination that hits every note: a crunchy cocoa and graham cracker base, a smooth custard buttercream filling, and a glossy semi-sweet chocolate shell on top.

The bottom layer comes together in a saucepan. Melted butter, cocoa, sugar, and a beaten egg form a fudgy binder for the graham cracker crumbs. Press it firmly and evenly into the pan. Gaps mean weak spots that crumble when you cut the bars.

The custard filling is the signature layer. Custard powder (Bird’s brand is traditional) mixed with butter and icing sugar creates a thick, sunshine-yellow cream that tastes like vanilla pudding in solid form. Add milk a teaspoon at a time until it spreads smoothly.

Work fast on the chocolate topping. It starts to set the moment it hits the cold filling, so pour and spread in one confident motion. Score the chocolate with a knife while it’s still slightly soft to make cutting easier later.

Kitchen Tips

• Chill each layer for at least 15 minutes before adding the next for clean, distinct layers
• Score the chocolate topping before it fully sets; cutting through hard chocolate cracks the surface
• Store in the fridge; these bars are meant to be eaten cold

Variations

• Add ½ cup shredded coconut and ½ cup chopped walnuts to the base for a more traditional Nanaimo bar
• Use peanut butter in the filling instead of custard for a chocolate-PB version
• Swap semi-sweet chocolate for white chocolate on top for a striking visual contrast
