If you’ve ever had the pleasure of biting into a Classic Nanaimo Bar, you already know why it’s a beloved treat. This no-bake Canadian dessert is layered with a chocolatey, nutty base, a dreamy custard-flavored buttercream middle, and a glossy chocolate topping that seals the deal. It’s a sweet that delivers texture and richness in every bite.

Named after the city of Nanaimo in British Columbia, these bars are as iconic in Canada as maple syrup. They’re the kind of dessert that you remember from childhood bake sales or holidays at Grandma’s house, always perfectly chilled and ready to be devoured. Once you try making them yourself, they’ll become a staple in your dessert rotation.

Why You’ll Love This Classic Nanaimo Bars Recipe

These bars are the ultimate crowd-pleaser. They’re easy to make ahead, require no baking, and taste even better after chilling. The base has a satisfying crunch from the graham crackers and coconut, the middle layer is smooth and sweet with just a hint of custard flavor, and the chocolate topping offers the perfect snap when you bite into it.

Whether you’re making them for a potluck, holiday gathering, or just because you want something indulgent, these bars never disappoint. Plus, they slice beautifully for serving and store well in the fridge or freezer.

What Kind of Chocolate Should I Use for the Topping?

The topping is a thin layer of melted chocolate mixed with butter to help it set with a soft bite. For the best results, use semi-sweet or dark chocolate baking squares or chips. Avoid using milk chocolate chips alone unless you prefer a sweeter finish. The richness of semi-sweet chocolate really balances the sweetness of the custard filling.

Ingredients for the Classic Nanaimo Bars

You’ll find most of these ingredients in a well-stocked pantry. Each layer has its own set of essentials that work together to create the iconic flavor and texture of a Nanaimo Bar.

Unsalted Butter: Used in every layer for creaminess and structure.

Granulated Sugar: Helps sweeten and stabilize the base layer.

Cocoa Powder: Brings rich chocolate flavor to the base.

Egg: Adds structure to the base when heated.

Graham Cracker Crumbs: Provide the crunchy backbone of the base layer.

Shredded Coconut: Adds texture and a hint of tropical flavor.

Chopped Walnuts: Give the base a nutty crunch (optional, but classic).

Powdered Sugar: Used in the custard buttercream for a smooth consistency.

Vanilla Custard Powder: Gives the middle layer its signature yellow hue and creamy taste (Bird’s is traditional).

Heavy Cream: Helps the custard filling become smooth and spreadable.

Semi-Sweet Chocolate: Used for the topping, giving that perfect bittersweet snap.

How To Make the Classic Nanaimo Bars

Step 1: Make the Base Layer

Melt butter, sugar, and cocoa powder in a saucepan over low heat. Whisk in the beaten egg and cook gently until the mixture thickens. Remove from heat, and stir in graham cracker crumbs, coconut, and walnuts. Press the mixture firmly into a parchment-lined 8×8-inch pan and chill.

Step 2: Prepare the Custard Filling

In a bowl, beat together softened butter, powdered sugar, custard powder, and heavy cream until smooth and fluffy. Spread evenly over the chilled base. Return the pan to the refrigerator to firm up.

Step 3: Add the Chocolate Topping

Melt chocolate with butter over a double boiler or in short bursts in the microwave. Let it cool slightly before pouring over the custard layer. Gently tilt the pan to spread evenly, or use a spatula. Chill until set.

Step 4: Slice and Serve

Once fully chilled, use a sharp knife dipped in hot water and wiped dry to slice cleanly through the layers. Wipe the knife between cuts for neat squares. Serve chilled or at room temperature.

How to Serve and Store Classic Nanaimo Bars

These bars are rich, so a little goes a long way. Cut them into small squares and serve them on a dessert platter or cookie tray. They’re ideal for holiday parties, bake sales, or simply as a fridge-ready indulgence.

You can store Nanaimo Bars in an airtight container in the refrigerator for up to a week. For longer storage, they freeze beautifully. Layer them between parchment paper and keep them in a sealed container. Just let them sit at room temperature for 15 minutes before serving.
