You would be hard pressed to find a Canadian who hasn’t heard or indulged in these legendary Canadian treats.

Similar to other no-bake layer bars, these dreamy chocolate confections have been popular since the 1950’s and few bars have gained the popularity as the Nanaimo Bar.

So, if you’ve never had a Nanaimo Bar before, you’re missing out on a culinary simple pleasure!

Where are Nanaimo bars from

Like the name would suggest, these tasty little confections come from Nanaimo, British Colombia. Though the exact origin and original recipe creator seems to be a mystery, these sweet treats are popular and well known throughout the country of Canada and beyond.

What are Nanaimo Bars

There are many no-bake three layer bars that have popped up all over that are similar in style and taste to Nanaimo bars, however, few have gained in popularity as much as the original Nanaimo Bar.

These bars consist of a dense cake or brownie style layer, a sweet thick custard layer, and a silky smooth rich chocolate topping.

Storage

At room temperature

While you can leave them out for a short period of time while serving, this no-bake dessert should not be stored at room temperature.

Since the bottom layer contains egg, it should be chilled for proper food handling.

Not only that the chocolate and custard layers will both soften as they become warm. This will quickly turn them into a bit of a mess to eat and handle.

Fridge

To store the Nanaimo bars in the fridge

  • Place the bars in an airtight container
  • Store in the refrigerator for up to 1 week
  • The bars can be served cold straight from the fridge

Freezer

The freezer is the perfect choice for longer storage of Nanaimo Bars. All of the layers freeze extremely well and is a great way of storing this make ahead dessert.

To store Nanaimo bars in the freezer

  • Place the bars in an airtight container
  • Store in the refrigerator for up to 3 months
  • Remove the bars to the refrigerator a few hours before serving to defrost

How to cut Nanaimo bars

Nanaimo bars can be a bit of a tricky business to cut cleanly. Once they are fridge cold they are pretty firm and hard to cut through, even if you use a sharp knife and manage to cut through the layers the delicate chocolate top will end up cracking and not looking it’s best.

To get that beautifully smooth chocolate top, make sure to allow the bars to sit out at room temperature to soften. This will be much easier to cut through and the chocolate layer will be slightly pliable and less likely to crack and fracture while you are slicing the bars.

After they are cut and portioned out, you can place them in an airtight container and store them in the refrigerator or freezer for longer storage.
