Keto Nanaimo Bars

by hungryelephant

Ever had a Nanaimo bar? Outside of Canada, I’m pretty sure it’s unheard of, but it’s one of the most delicious things ever. Thankfully I made some yummy keto Nanaimo bars!

It’s a 3-layered, no bake bar. 1st layer is a graham cracker crust, 2nd is a custard and the final, top layer is a chocolate ganache. Of course we cant use graham crackers, so today I ‘ketofied’ the Nanaimo bar, making it very low carb.

A lot of people have been asking what is custard powder? Well, basically it is a powder that allows you to make custard without eggs! I used Bird brand. It’s usually found in supermarkets in Canada and the UK/Europe but might be hard to find in the US. You can always replace it with a thick stovetop custard. 

One suggestion I will make is to only use 1 cup of sugar for the custard (2nd layer). While I enjoyed mine, I thought it was a little too sweet. So step it back a little and it will be perfect.

What is custard powder?

Hi Sara,

Custard Powder is a British no-egg custard mix. You can buy it online at walmart, target, amazon.. etc!

I couldn’t find it at Wal-Mart so I ordered it on Amazon. I can’t wait to make these!

Made these over the weekend with my daughter, they were excellent! I will have to find a substitute for the icing sugar or grind my substitute sugar so that it is finer, as was suggested.
Found the custard powder at Provigo (formerly Loblaws in Quebec).

My mother used to make these when I was a kid!! So pleased to find a low-carb version – and I’m from New Zealand, with no Canadian connections at all ☺ But Im surprided you use custard powder; does that meet lc definition? Is there another way to do it?

Hi pauline! The custard powder does have carbs in it, but I think it was like 9 for 2 tbsp. alternatively you could just make a thick low carb vanilla custard and use that instead! Same thing! The custard powder is just a way to make eggless custard.

OMG I just started keto and was trying to figure out how to make my favorite Christmas time dessert! This is AMAZING! I’m an ex-pat and everyone I’ve made Nanaimo Bars for here in the US has loved them…and now are all on diets (not related…LOL). Thank you for saving me the steps to figure it out! 🙂

Is custard powder keto-friendly? Is there anything that could be used in its place?

hungryelephant March 25, 2019 - 7:19 pm

I would just make a generic thick vanilla custard on the stovetop!
