Low Carb Naniamo Bars Recipe

Low Carb Sugar Free Nanaimo Bars

Naniamo Bars are a Canadian classic that I’m happy to promote. They have a soft not overly sweet chocolate base that’s made with cocoa powder, shredded coconut and chopped nuts (usually walnuts or almonds but pecans also work well!)

They then have a creamy filling made typically using a pudding mix of some sort or custard powder (we’ll talk a bit more about that below). Finally they are topped off with a thin layer of melted chocolate. Pop them in the fridge, (no baking required) and then you have some beautiful looking bars that everyone will love! 

I brought these to a birthday party last week and most people that tried this recipe actually thought they were just regular Nanaimo bars. They were a huge hit! So definitely give them a try if you know some picky family members/friends.

Ingredients In Low Carb Nanaimo Bars

  • Almond Flour – I use the Kirkland Costco brand of almond flour (I buy it in bulk on Amazon or at Costco itself occasionally) for this recipe. As I’ve noted in many of my past recipes, the brand of almond flour can affect the final outcome of the recipe because absorbency can vary depending on how the flour has been processed.
  • Cocoa Powder – I use the Rodelle brand again from Costco. I find it to taste better than other brands!
  •  Powdered Monkfruit Erythritol Sweetener  –   I use the SoNourished brand for both granular and powdered sweetener and love it! The powdered is the best option for no-bake goods and desserts where you want a very smooth final product like this one. 
  • Custard Powder – I know I’ll get a few questions about this one so let me explain, custard powder DOES contain cornstarch which has ~9g of carbs per tablespoon. We are using 2 tbsp for this Low Carb Nanaimo bar Recipe which is 18g of carbs BUT this is divided by 24 bars only adding 0.75g of carbs to each bar! This is very small and for most individuals on a ketogenic diet, this is completely fine as long as you track the low carb nanaimo bars into your daily carb limit like anything else. BUT if you are very strict keto, you can try a pastry cream like the one I used for my Keto Boston Cream Donuts. You may need to double the filling from that recipe, also note that it’s a little softer than a filling made with custard powder. FINALLY if you also don’t want to use that pastry cream, you can make my Keto Cheesecake Nanaimo Bars that replace a traditional pastry cream filling with a cheesecake filling (they are also delicious and were a hit when I brought them to a Christmas party!)

Tools I used To Make This Low Carb Nanaimo Bars Recipe

  • Low Carb Substitution Guide – This is totally optional but if you like my recipes, I now have a $5 guide available with all of the substitutions I use to create every recipe on my site. You can use this to convert old traditional recipes and create new keto recipes! You can purchase it here and/or read more if you are interested. 🙂 I appreciate your support so much guys!
  • Nutritional Food Scale – AKA my best friend. This little buddy has been with me for over 4 years and never fails. Perfect measurements and only needs the batteries replaced maybe once a year!
  • 11×7 Inch Pan – This is a more unconventional size of pan but it works really great for this recipe. If you don’t have one then you can use and 8×8 inch pan, just know the bars will be a little bit thicker than the ones in the photos!

Tips For Making Low Carb Nanaimo Bars

  • When spreading your filling, do your best to evenly cover the entire base of the bars for the best final result.
  • Make sure BEFORE you spread your final chocolate layer that your bars have completely hardened in the fridge to prevent mixing of the two layers. 
  • Feel free to add different chopped nuts to the base of these bars! Walnuts are just a common choice. 
  • When cutting these squares, use a large, sharp knife. Have a cup or bowl of very hot water beside you that you can dip the knife in and a paper towel to wipe it off after. Using a hot knife will prevent the chocolate topping from cracking much as the knife will just melt through that layer. We used to do this when I worked at a French bakery slicing giant Nanaimo bars every day!
