Named after the city of Nanaimo in British Columbia, the first time this square was published under that name was in the early 1950's in the Vancouver Sun newspaper! This version of the original bar is from Company's Coming - 150 Delicious Squares! Later versions change the vanilla custard layer to mint or peanut butter but the original is my favourite. You can make this a day ahead of a special occasion or keep it in the freezer. I used to freeze half because I'm very weak & I would eat the whole thing myself BUT I soon discovered that it tastes good even when its frozen!

It's impossible to spread the custard layer without refrigerating the bottom layer - I just ended up with a giant mess and had to go back to the store and do it all again. Poor instructions.

This was by far one of the best desserts I've made! Thank you so much for posting this! YUMMO! I could not find the custard powder so I replaced with 3 tbsp vanilla instant pudding and I made the replacement suggestion for the icing sugar and my family was WOW'd! I will absolutely be making this again! Wish I could give more then 5 stars =)
