Mom’s Nanaimo Bars – Our Authentic Canadian Dessert

Nanaimo bars are a classic Canadian dessert. This is Mom’s recipe, and it is a bit less sweet than most, which is a good thing! They are made with a graham-crumb, coconut, and nut crust, topped with a layer of buttery custard, and finished with chocolate. You’ll love this no-bake dessert!

It’s no surprise that Nanaimo bars hold a special place in my heart. As a Canadian, I’ve eaten my fair share over the years, and I can confidently say that nothing compares to a homemade Nanaimo bar. With their chocolate-coconut base, creamy custard filling, and glossy chocolate topping, they’re one of Canada’s most iconic desserts for good reason.

This recipe comes from my mom, and it’s the one I come back to every holiday season, potluck, and family gathering. The layers are perfectly balanced, the custard filling is silky and rich, and the texture is exactly what a Nanaimo bar should be. In my opinion, they’re miles better than the pre-made versions you’ll find in bakery cases around British Columbia.

If you’ve never made authentic Nanaimo bars before, don’t worry. The ingredients are simple, the steps are straightforward, and the results are absolutely worth it. Once you’ve tasted a homemade Nanaimo bar with real custard powder and that classic chewy-crunchy base, it’s hard to go back.

The ingredients are classic and traditional. Cocoa powder, graham cracker crumbs, coconut, and walnuts create the signature base, while powdered sugar, butter, and Bird’s Custard Powder make the creamy middle layer. A simple mixture of chocolate and butter finishes everything off with the glossy topping that makes Nanaimo bars instantly recognizable.

What is a Nanaimo bar?

A Nanaimo bar is one of my favorite classic Canadian desserts. While it’s spread all over Canada, it originated in the city of Nanaimo on Vancouver Island in British Columbia—just a hop away from The Endless Meal headquarters! These no-bake tasty treats are made by layering three distinct tiers: a crumbly base, a creamy custard middle, and a chocolate topping. The result is like a layered bar cookie. They are loved year-round and hold a special place as a festive-season staple in Canada.

Ingredients

Bottom Layer

• ▢ ½ cup butter
• ▢ 5 tablespoons cocoa powder
• ▢ ¼ cup granulated sugar
• ▢ 1 large egg
• ▢ 1 ¾ cup Graham cracker crumbs
• ▢ ¾ cup fine coconut
• ▢ ¼ cup chopped walnuts

Middle Layer

• ▢ 3 cups powdered sugar
• ▢ ¾ cup butter (softened)
• ▢ ¼ cup milk
• ▢ ¼ cup Bird's vanilla custard powder

Top Layer

• ▢ 8 ounces shaved dark chocolate or chocolate chips
• ▢ 4 tablespoons butter

Instructions 

Bottom layer

• Lay a piece of parchment paper in a 9×11-inch pan, letting some hang over the sides. (This makes it easier to remove the Nanaimo bars.)
• Melt the butter in a medium-sized pot over medium heat. Whisk in the cocoa powder and sugar. Remove the pot from the heat then add the egg and whisk until it has thickened, about 30 seconds. Stir in the Graham cracker crumbs, coconut, and walnuts. Press the crust firmly into the prepared pan.
  ½ cup butter, 5 tablespoons cocoa powder, ¼ cup granulated sugar, 1 large egg, 1 ¾ cup Graham cracker crumbs, ¾ cup fine coconut, ¼ cup chopped walnuts

Middle layer

• Add all the middle layer ingredients to a large bowl and cream them together using electric beaters. Pour the custard over the first layer and smooth the top.
  3 cups powdered sugar, ¾ cup butter, ¼ cup milk, ¼ cup Bird's vanilla custard powder
• Place the pan into your fridge for at least 20 minutes, or until the custard is firm.

Top layer

• Add the chocolate and butter to a medium-sized pan over low heat and let both melt. Whisk to combine and then pour the chocolate over the custard. Smooth the top first with a spatula then by gently tapping the pan on your counter.
  8 ounces shaved dark chocolate or chocolate chips, 4 tablespoons butter
• Chill in your fridge for about 20 minutes, or until the chocolate is soft-set. Cut the Nanaimo bars into bars then place them back in your fridge until they are completely set. (Cutting the bars first prevents the chocolate from cracking.)
• Store the bars in a covered container in your fridge for a week or up to three months in your freezer. The bars can be eaten cold or at room temperature – they take about 10 minutes to warm once out of the fridge.
