All About Nanaimo Bars

No-bake desserts have been around for centuries and started to grow in popularity after the Second World War when staples like butter and sugar started to be more readily available.

There are conflicting theories as to when and where these no-bake Nanaimo Bars were created but research tells us these bars gained their notoriety after Expo 86 in Vancouver. 

In 2006 the Nanaimo bar was voted Canada’s favorite confection by the newspaper National Post. As such the popularity of these bars has continued to grow.

Scroll down to the printable recipe card for exact measurements and step-by-step instructions.

FOR THE BASE (Bottom Layer)

Unsalted butter – Butter adds a nice richness to the base in this recipe. Salted butter can be used in its place but I prefer to use unsalted and add salt if needed. To make this recipe vegan you can use a vegan butter like Earth Balance.

Granulated sugar – A pantry staple.

Cocoa powder – I prefer unsweetened cocoa powder like Hershey’s.

Salt – Any salt will do but I typically use table salt.

Large egg – Any kind of egg will work. 

Graham cracker crumbs – You can usually find the crumbs ready-made in the baking aisle of the grocery store. If you can’t find them you can buy graham crackers and process them in the food processor to make crumbs. If you are unable to find graham crackers where you live, a good substitute are digestive biscuits.

Pecans – Finely chop the pecans or feel free to substitute another nut like walnuts or almonds if you don’t have pecans on hand. If you want to avoid nuts you can omit them or use seeds instead. 

Unsweetened shredded coconut – Coconut flakes also work well, just process them to make them into shreds.

FOR THE FILLING (Middle Layer)

Unsalted butter – Softened at room temperature

Custard powder – Custard powder is usually found in the baking aisle of the grocery. If you are unable to find custard powder, vanilla pudding works well. For a different twist try adding a teaspoon or either ground espresso or mint extract to the pudding. Or use chocolate pudding.

Vanilla extract – Pure vanilla extract or artificial vanilla extra work well. You can also use vanilla powder.

Powdered sugar – Also known as icing sugar. No substitutions here.

Heavy cream – Heavy cream will add richness but reduced-fat cream or milk will also work. 

FOR THE TOP LAYER

Semi-sweet chocolate – You can substitute semi-sweet chocolate chips if you don’t have semi-sweet chocolate. Dark chocolate works well too or try using white chocolate for a different taste. 

Heavy cream – Heavy cream adds richness here too but reduced-fat cream or milk will also work.

How To Make Nanaimo Bars

Line a 9 x 9” baking dish with tin foil or parchment paper.

For the base layer, melt butter in a double boiler over low heat. Mix in sugar, cocoa powder, and salt and mix until combined.

Slowly add the beaten egg to the mixture, whisking constantly to prevent the egg from cooking. Return to the double boiler and cook for an additional minute or two for slight thickening. Your mixture should resemble a fudge-like consistency when ready.

Add graham cracker crumbs, shredded coconut, and pecans. Mix until hydrated.

Pour into the prepared baking dish and spread in an even layer. Store in the fridge until ready for the second layer.

Add butter, custard powder, vanilla, powdered sugar, and heavy cream to the mixer with a paddle attachment. Mix until light and fluffy. If too thick, add a small amount of cream until a spreadable consistency has been reached.

Spread mixture on top of the first layer. Store in the freezer while chocolate ganache is made.

Add semi-sweet chocolate and cream to a heatproof bowl and melt over a double boiler.

Once smooth, remove the pan from the freezer and pour melted chocolate over top, spread quickly and evenly.

Return the pan to the refrigerator for 15 minutes. Remove and score chocolate with a sharp knife.

Return to the fridge to set further. When the chocolate has completely set, remove from the fridge, and cut squares.

Serve.

Tips & Tricks

Take butter and the egg out of the fridge before you begin so they can come to room temperature.

Add a touch of oil to the topping layer to make it easier to spread. 

Make sure to chill each layer before adding the next one. 

How to Store 

Nanaimo Bars will last for several days on the counter. If you live in a warm climate it may be best to store in the fridge.
