Nanaimo bars are Canada’s most famous dessert—a glorious three-layer no-bake bar named after the city of Nanaimo in British Columbia. With a chocolate-nut base, a creamy vanilla custard filling, and a smooth chocolate top, they’re absolutely irresistible.
The contrast of textures—crunchy base, silky filling, and firm chocolate topping—is pure magic. This recipe delivers the authentic version: a buttery graham cracker and coconut base, a luscious custard center, and a perfect chocolate glaze. Once you try them, you’ll understand why these bars have achieved legendary status.
Instructions
Make the Bottom Layer
In a medium saucepan over low heat, melt the butter, sugar, and cocoa powder, stirring constantly until smooth. Remove from heat. Gradually whisk in the beaten egg, stirring vigorously until the mixture thickens (the heat from the saucepan will cook the egg).
Return to low heat if needed, stirring constantly for 1-2 minutes until slightly thickened. Remove from heat. Stir in the graham cracker crumbs, coconut, and walnuts until well combined.
Press into Pan
Press the mixture firmly into the bottom of an 8×8 or 9×9-inch baking pan lined with parchment paper. Use the bottom of a measuring cup to press it down very firmly and evenly. Refrigerate while you make the middle layer.
Make the Middle Layer
In a medium bowl, beat the softened butter with an electric mixer until creamy. Gradually beat in the milk, vanilla pudding mix, and powdered sugar until smooth and fluffy. Spread evenly over the chilled bottom layer.
Chill
Refrigerate for at least 30 minutes, until the middle layer is firm.
Make the Top Layer
In a small saucepan or microwave, melt the chocolate and butter together, stirring until smooth. Let cool slightly, then pour over the chilled middle layer. Spread evenly with an offset spatula.
Chill Thoroughly
Refrigerate for at least 2 hours, preferably overnight, until the top layer is firm and set.
Slice and Serve
Use the parchment overhang to lift the bars out of the pan. Place on a cutting board and use a sharp knife to cut into squares. For clean cuts, wipe the knife between slices. Serve cold or at room temperature.
Pro-Tips for Nanaimo Bar Perfection
- Press the Base Firmly: A firmly pressed base is essential for bars that hold together when sliced. Use the bottom of a measuring cup and really lean into it.
- Cook the Base Properly: The egg in the base needs to be cooked gently to thicken the mixture—don’t skip this step.
- Use Instant Pudding Mix: The powder (not prepared pudding) is what gives the middle layer its structure and flavor.
- Chill Between Layers: Chilling each layer ensures clean, distinct layers when sliced.
- Wipe the Knife Clean: For picture-perfect squares, wipe the knife between each cut.
- Room Temperature or Cold? Nanaimo bars are delicious both ways—some prefer them cold, others at room temperature.
- Variations: Try mint chocolate, peanut butter, or mocha versions.
- Make Ahead: These bars keep well in the refrigerator for up to a week, or in the freezer for up to 3 months.
These Nanaimo Bars are Canada’s legendary treat—absolutely irresistible.
