This classic Nanaimo bar recipe has been handed down through Canadian families for generations!

What is a Nanaimo Bar?
- Named for the city of Nanaimo in B.C., Canada, Nanaimo bars are 3 layers of rich and deliciously distinctive stacked-up flavors in one easy-to-make, no-bake bar!
- A top layer of rich chocolate covers a creamy middle layer of cocoa buttercream which is spread over a bottom cookie layer made with chocolate-coconutty goodness.
- No-bake and easy to make and Nanaimo bars freeze beautifully so why not keep some on hand for last-minute treats?
What’s in a Nanaimo Bar?
Three layers create a perfect combination of crunchy, creamy, and crispy chocolate!
The base can be baked, or unbaked. The combination of cocoa, graham cracker crumbs, coconut, and walnuts provides a chewy and dense base similar to a brownie that’s perfect for piling on two more layers of good stuff! Gluten-free graham crackers can be used or you can make a flourless peanut butter base and create a Reese’s Nanaimo bar!
Custard powder, powdered sugar, and butter make up the melt-in-your-mouth middle layer that makes Nanaimo bars so famous. Look for custard powder in the pudding section of your supermarket or buy some on Amazon. A bit of mint extract and some green food coloring will make a minty-flavored Nanaimo bar that’s perfect for St. Patrick’s Day or summertime parties!
This recipe tastes best when you use the best ingredients! Good quality chocolate chips or baking squares help marry all the other flavors together. You can even double the recipe to create an extra tall, extra decadent bar.
It’s easy to switch up the ingredients or add mix-ins to this Nanaimo bars recipe. Use pecans or pistachios instead of walnuts in the base, and a rum, maple, or bourbon extract in the buttercream filling, or pour a thin layer of white chocolate on the topping and make decorative swirls with a toothpick. Make them without nuts and use seeds or even homemade granola.
How to Make Nanaimo Bars
Nanaimo bars are a must-have on a cookie tray any time of year!
- Heat butter, sugar, and cocoa in a pan and stir until smooth. Add egg and vanilla, as directed in the recipe card below.
- Stir in graham crackers, coconut, and walnuts. Press into the bottom of a pan and refrigerate.
- Cream butter until fluffy. Add powdered sugar, custard powder, and milk and beat until smooth.
- Spread the custard mixture evenly over the crust and refrigerate.
- Melt chocolate and butter in the microwave at intervals until melted and smooth.
- Gently spread the chocolate topping over the custard.
Tips For Success
- Use a wooden skewer to make small lines in the top layer. Scoring the top keeps the chocolate from breaking while you cut them.
- Make sure each layer is cooled completely or the buttercream middle layer will melt.
- Refrigerate Nanaimo bars until they are set before cutting into squares and serving.
Best Way to Store Nanaimo Bars
Keep Nanaimo bars in the refrigerator in a covered container for up to 4 days.
Freeze bars by wrapping them in plastic wrap and placing them in a zippered bag. Thaw in the refrigerator.
