Because it's three layers, this sounds hard but it's worth it. My son is famous for making and taking these in to work. I've heard other names but here in the Northwest everyone knows them as Nanaimo bars. They are sold on British Columbia Ferries and at coffee stands. If you can't find custard powder, I've used instant pudding mix with good results.
These were delicious. Here's a tip for beginners. Don't add the egg to the saucepan...if it's too warm the egg will CURDLE. My mom told me to slowly beat about half of the chocolate mixture into the egg, a little at a time, so that it won't curdle from the heat. Hope this helps, thanks for the great recipe, I will make again for sure! - 27 Jan 2008 (Review from Allrecipes US | Canada)
So very delicious! I doubled the recipe to fit a 9x13 pan and it turned out fabulous. Tip for bottom layer: To avoid curdling the egg, I beat the eggs in a separate bowl and slowly added 1/2 cup of the melted cocoa mixture to the egg while whisking, then slowly added the egg mixture to the rest of the cocoa mix while whisking. Turned out perfect! - 06 Dec 2007 (Review from Allrecipes US | Canada)
Excellent Recipe!! Living in Canada I've been making Nanaimo bars every Christmas for as long as I can remember! The recipe I usually use is a little different than this one but what a difference a few changes can make. The filling is nice and firm, the crust moist and the topping not too hard! It cuts into squares excellent (I line my pan with parchment paper so it's easier to get out of the pan and cut.) The top doesn't crack when you're cutting it and the filling doesn't squish out the sides and the bottom stays together nicely. This is my new Nanaimo bar recipe that I'll be using from now on!!
