Keto Nanaimo Bar Recipe – A Low Carb and Gluten Free Keto Dessert

If you have never had this iconic Canadian dessert bar, well  what can I say, I am so sad for you! Let’s fix that right now with this Keto Nanaimo Bar Recipe!

What is a Nanaimo Bar you ask?  Traditionally, it is a 3 layer no bake bar. The bottom layer is a chocolate coconut wafer concoction. The middle layer is a custard and the top layer a nice dark chocolate ganache.

The Nanaimo Bar originated in Nanaimo, BC which is not too far from where I live. The first recorded Nanaimo bar recipe (according to the wikipedia) was in the Nanaimo Hospital Ladies Auxillary cookbook in 1952.

These gluten free Keto Nanaimo Bars are also featured in The 12 Days of Keto Christmas Treats blog post, which has more amazing Keto and Low Carb Christmas desserts.

The two most important things you need to know about Nanaimo Bars?   One, they are over the top delicious and a perennial favorite around here, and 2) They are actually super easy to make! So don’t be scared by the 3 layers!

We Canadians eat these by the ton in my geographical location of the Canadian West Coast. The local supermarkets sell giant slabs of it at Christmas. So it was real important that I make this into a Keto Nanaimo bar recipe or I’m done for!

What will I need to make these gluten free nanaimo bars?

All of the ingredients are easily obtainable from any major supermarket. If you are in a remote location then Amazon is your friend so I’ll share the links for the harder to find ingredients. (Note, these are affiliate links meaning I get a small commission if you order them, which doesn’t affect the price you pay)

There’s no baking involved here which is always a bonus. You’ll just need a 9 x 12 casserole pan, because honestly there is no point in making a small measly pan of these.

You’ll be just making it all over again, so it’s better to make lots just the one time. Besides, you can freeze these too.

  1. this is the recipe I use every year!! you should be rated online honestly yours shows up with no reviews and it’s the best out of them all I’ve made a few with top review and they aren’t that great..I’ve grown up on this stuff and being able to make a sugar free version is awesome thanks for sharing!!!


  2. This is absolutely fantastic! Thank you for this recipe!
    I plan to make this soon, but for now wanted to share my ideas for my substitutions I will need to make for my allergies:
    —Egg – will replace with Gelatin
    —Bird’s Custard Powder – I will replace it with part gelatin and part powdered coconut flour (Coconut flour buzzed in the coffee grinder to make it a super fine powder – it won’t need much because it thickens well, plus the gelatin will do a great job of thickening too). Could also add collagen possibly, depending how it blends.
    —-Erythritol – will replace with powdered Allulose.
    Thanks again!

  3. I know this is an older post but given the current events, I’m home with a lot of time to find and make new recipes. This recipe for nanaimo bars is great!!! I didn’t grow up with these but was introduced to them by a Canadian colleague. I followed this recipe and the bars turned out really well. Decadent and still very low carb. The only change I made was the topping. I had stevia-sweetened chocolate chips on hand so I just melted those with the butter for the topping. Great!

    1. I know what you mean, I have been making cabbage rolls and baking way more than usual! Thanks for your kind words!

  4. These look amazing!! Are these Keto? I noticed the Custard Powder has cornflour. What are the carbs for the Custard Powder pls? THank you!!

    1. People who are doing ‘clean keto’ would definitely poo poo this dessert! I normally am pretty clean keto but at Christmas I am dirty keto or I’m not going to make it through the holidays, you know what I mean!? So about ingredients being ‘keto’, there’s actually no such thing as a keto food. Ketosis is a metabolic state brought about by keeping your carbs very low. These Nanaimo Bars are 3 net carbs (4 total carbs) per bar. If you ate several, sure it will kick you out of ketosis. I bake a sheet in December and freeze the bars and kind of use them as needed. The 3tbsp of Birds powder contribute about 26 carbs to the recipe, so less than 1 carb per bar is from the Bird’s powder. I hope that helps and make your decision based on what’s best for you and your way of doing Keto. (But watch out for the Keto police, they are everywhere!) :-)

  5. Hi! I was just looking over the recipe. Sounds so delish!
    I noticed beaten egg added in bottom layer but listed in ingredients.
