Canadian Nanaimo Bars

Posted By Chef Rodney on October 16th, 2017 under Squares & Bars

A home cook who relies too much on a recipe is sort of like a pilot who reads the plane’s instruction manual while flying.

Growing up, Nanaimo Bars were one of my favorite sweets. Sweet custard sandwiched between chocolate. How can you go wrong?

These Nanaimo bars are probably one of my most requested desserts. I love making them for others. They are pretty easy to make but do require some time in the fridge to settle. I have share this recipe with many and it would appear that custard powder is not that easy to locate. While I don’t have any problems finding it locally here in Southern California, you can easily find the same brand I use on Custard Powder on Amazon


For coconut lovers, you can add a bit of shredded coconut to the base mixture for something a little different. And if you really love custard, you can double the ingredients for the filling.


How to Make this Recipe


Make the base

In a sauce pan, combine first 5 ingredients and cook over medium heat stirring constantly until smooth and slightly thickened. Remove from heat.


Add graham cracker crumbs to the mixture and mix well. The batter should be thick at this point. Pack the mixture into a 9 inch square pan.


Make the filling

Combine 1/4 cup butter, milk, 2 tsp vanilla and custard powder. Beat for 5 minutes. Blend in powdered sugar. Spread custard filling over the base and chill in the refrigerator for at least 15 minutes.


Make the topping

In a small saucepan, melt the chocolate chips and 1 Tbsp butter stirring frequently. Spread the chocolate mixture over the custard filling.


Let dish cool completely in the refrigerator before cutting into squares and serving.

Chef's Notes

- Add a little shredded coconut during step 2 for something a little different.

When my children were growing up this recipe was one of their favourite. I usually tried to make them at least once a month (they would have liked them every week). They were great for school lunches and i usually kept them in the freezer so they would not eat them all at once. They just took 5-10 minutes to get to room temperature. And now that the children are grown up I make them to take to gatherings and are always a huge success.
