I have been making Nanaimo bars my whole married life (26 years). There are many different recipes but they are generally similar. Nanaimo bars are deliciously creamy, chocolatey, nutty squares that do not require oven baking. They are by far the favorite in this household over the holidays and pretty much a big hit for those who have tried them. No one person that I have asked in Southern California has ever heard of them. I know this because as soon as you say Nanaimo, they say "Nan what?" They are delicious and I grew up eating them. No they are not calorie free, nor are they sugar or fat free. They are filled with everything that makes them worth every caloric bite. And I say if it's not worth the calories, why eat it?
