When we lived in Canada, I fell in love with Nanaimo Bars. Canadians are amazing bakers. They are something I have only ever seen in Canada, and when one is made well, it is heaven.

It is Thanksgiving Day, and I am sitting at my kitchen table writing about Christmas cookies. What is wrong with this picture? Since I enlisted the help of my guests, this Thanksgiving has been a breeze. My first two turkeys are resting, the gravy is made and waiting to be reheated, the cranberries are done, the rolls are rising, and the tart is waiting patiently to be eaten. My house is even clean! I actually have time to catch up and add my Week 9 of Christmas post.

When we lived in Canada, I fell in love with Nanaimo Bars. Canadians are amazing bakers. They are something I have only ever seen in Canada, and when one is made well, it is heaven. I prefer the traditional version like this one, but have seen various flavors, like peanut butter and mint. A Nanaimo Bar is 3 layer bar, the bottom being a crust of walnuts, coconut, and chocolate. The middle layer is a buttercream variation, and the top is a thin layer of chocolate. In the US, we call this a bar cookie, but in Canada, they call it a square. Whatever you want to call it is fine with me, but I am calling it delicious.

*This recipe calls for custard powder. I found mine in the ethnic foods aisle, with the British food, but you can order Bird’s custard powder online.*  

Homemade Nanaimo Bars Ingredients

Crust:

  • 1/2 cup butter
  • 1/4 cup brown sugar
  • 3 Tablespoons cocoa
  • 1 egg
  • 2 cups graham cracker crumbs
  • 1 cup coconut
  • 1/2 cup chopped walnuts
Butter, sugar, flour, cocoa powder, eggs, baking ingredients for baking cookies or cake.

Middle Layer:

  • 2 cups powdered sugar
  • 1/4 cup room temperature butter
  • 1/4 cup heavy cream
  • 2 Tablespoons custard powder

Chocolate layer:

  • 3 ounces chocolate chips
  • 1/4 cup butter

How to Make – The Steps

Step 1: Start with the crust. Melt together the butter, brown sugar, and cocoa.

Chocolate and butter in mixing bowl for baking recipe preparation.

Step 2: I did mine over a double boiler, but if I had a microwave, I probably would have done it that way.

Deep chocolate ganache being made in a stainless steel bowl with a whisk attachment.

Step 3: Beat the egg, and quickly whisk it into the hot chocolate mixture. You need to add the egg slowly and keep the whisk moving, otherwise, you will have scrambled eggs. Not good.

Step 4: Mix in the graham crackers, coconut, and walnuts.

Crumble topping mixture for baked dessert or pie, seasoned with spices and sugar.

Step 5: Press the crust into an 8×8 pan that has been lined with parchment. Put the crust into the fridge to chill for a half hour.

Rich, crumbly homemade dessert topping or crust in a lined baking pan. Perfect for baking or dessert recipes.

Step 6: Make the buttercream layer, but cream together the powdered sugar, butter, and custard powder. Add the cream slowly, and beat until light and fluffy, about 5 minutes.

Cream cheese frosting being spread on a dessert layer in a baking pan.

Step 7: Spread the cream layer evenly over the crust. Back in the fridge for another half hour or so.

Golden layered cake batter in a baking pan before baking.

Step 8: Melt together the butter and chocolate (either a double boiler or microwave) and pour over the chilled cream layer.

Step 9: Back in the fridge to set up.

Step 10: Cut them into small squares (they are really rich) and keep them in the fridge. My Canadian daughter loves these. She must know that they are part of her heritage. This recipe was adapted from The Marion House Book.
