Nanaimo Bars: A Canadian Classic with Six Delicious Twists

The first time I tasted a Nanaimo bar, I was a kid visiting my aunt in Vancouver. She pulled a tray of these layered squares from the fridge, and the contrast of the rich chocolate, creamy custard, and chewy base was pure magic. I remember how the chocolate topping would crack just so when you bit into it, yielding to the smooth, sweet filling. To this day, that first bite remains a vivid memory, a taste of pure Canadian comfort and my aunt’s warm hospitality. These bars are surprisingly easy to make, and I’m excited to share my recipe – along with a few exciting flavor variations!

Recipe Overview

• Prep Time: 30 minutes
• Chill Time: 2 hours
• Total Time: 2 hours 30 minutes
• Servings: 16
• Yield: 16 bars
• Dietary Type: Not Gluten-Free

Ingredients

For the Base:

• ½ cup butter
• ¼ cup sugar
• 5 tablespoons cocoa powder
• 1 egg, lightly beaten
• 1 teaspoon vanilla extract
• 1 ½ cups graham cracker crumbs
• 1 cup shredded coconut
• ½ cup walnuts, chopped (or almonds or pecans)

For the Filling:

• ⅓ cup butter
• 3 tablespoons custard powder, Bird’s brand (or substitute vanilla jello pudding powder)
• ¼ cup milk
• 3 cups icing sugar

For the Topping:

• 8 ounces semisweet chocolate
• 2 tablespoons butter

Equipment Needed

• 9-inch square baking pan
• Heavy saucepan
• Wooden spoon or electric mixer
• Measuring cups and spoons
• Whisk
• Refrigerator

Instructions

1. Prepare the Base: In a heavy saucepan, melt ½ cup butter over medium-low heat. Be careful not to burn the butter; low and slow is key here!
2. Combine Dry Ingredients: Stir in ¼ cup sugar and 5 tablespoons cocoa powder until the mixture is smooth and well combined. This creates a rich, chocolatey base for our bars.
3. Add Egg and Vanilla: In a separate small bowl, whisk 1 egg with 1 teaspoon vanilla extract. Gently stir this mixture into the butter mixture in the saucepan. The egg helps bind the base together.
4. Remove from Heat: Remove the saucepan from the heat. It’s crucial to take it off the heat at this stage to prevent the egg from scrambling.
5. Incorporate Crumb Mixture: Stir in 1 ½ cups graham cracker crumbs, 1 cup shredded coconut, and ½ cup chopped walnuts (or your choice of nuts – almonds or pecans work beautifully too). Ensure everything is evenly distributed.
6. Press into Pan: Grease a 9-inch square pan. Press the crumb mixture evenly over the bottom of the prepared pan. Use the back of a spoon or your fingers to create a firm, even layer.
7. Chill the Base: Chill the base in the refrigerator until it is set, for at least 20 minutes. This firming up is essential for layering the filling properly.
8. Prepare the Filling: In a mixing bowl, beat ⅓ cup butter with a wooden spoon or an electric mixer until it’s light and fluffy. This creates a smooth base for the custard.
9. Combine Custard and Milk: Beat in 3 tablespoons custard powder (Bird’s brand is traditional, but vanilla jello pudding powder works as a substitute) and ¼ cup milk. Ensure there are no lumps.
10. Gradually Add Sugar: Gradually beat in 3 cups icing sugar until the filling is smooth and creamy. Be careful not to add all the sugar at once, as this can create a powdery texture.
11. Spread Filling: Spread the filling evenly over the chilled base. Use an offset spatula for a smooth, professional finish.
12. Chill Filling: Let the filling set in the refrigerator. This may take an hour or so. Patience is key for a clean cut later.
13. Prepare the Topping: In a heatproof bowl set over a saucepan of simmering water (or in the microwave in 30-second intervals, stirring in between), melt 8 ounces semisweet chocolate and 2 tablespoons butter together.
14. Stir Until Smooth: Stir the chocolate and butter until the mixture is completely smooth and glossy.
15. Spread Topping: Spread the melted chocolate evenly over the chilled filling. Again, use an offset spatula for the best results.
16. Chill and Score: Store the bars in the refrigerator until the chocolate topping begins to harden. While the chocolate is still slightly soft, score the topping into 16 small bars (bites). This will make it easier to cut them cleanly later.
17. Cut and Serve: Cut the bars completely before the chocolate is totally solid. Use a hot knife, wiping it clean between cuts, for the neatest squares.

Expert Tips & Tricks

• For a richer base, try using melted butter cookies instead of graham cracker crumbs.
• If you find the chocolate topping is cracking when you cut it, try adding a teaspoon of vegetable oil to the melted chocolate. This will make it more pliable.
• Don’t overbeat the filling, as this can make it too soft.
• For extra flavor, toast the coconut before adding it to the base.
• If you don’t have custard powder, you can use cornstarch as a substitute. Use 1.5 tablespoons of cornstarch mixed with 1.5 tablespoons of milk.

Serving & Storage Suggestions

Serve Nanaimo bars chilled, straight from the refrigerator. They are the perfect treat for parties, potlucks, or a simple afternoon snack. Store leftover Nanaimo bars in the refrigerator for up to a week in an airtight container. You can also freeze them for up to 2 months. Thaw them in the refrigerator before serving.
