Marilyn:  These bars are known by several names.  In our family they were known as 3-Layer Bars.  Mom only made them at Christmastime-usually several batches.  She gave most of them away to family & friends.  The Lears usually received some, & in their family Aunt Margaret tells me they were known as Aunt Ann's Bars.  I have also made these bars at Christmastime for decades & given the first batch or 2 away to family & friends.  I think my kids were always anxious that I might give them all away, but I always made sure that they got some, too!  Many have requested the recipe over the years  & when I pass it on, I call them Nanimo Bars [I found the recipe in an old recipe book of Mom's & that is what they were called.  I liked that name because Carl & I went thru a town on Vancouver Island on our honeymoon by the name of Nanimo.]   I've been retired for two Christmases now, & I'm still hearing that people with whom I worked miss them when Christmas rolls around.  My grandson, Brendan, 4 , helped me make them for the first time in Dec. '03 & had great fun mixing up that "mud" for the bottom layer & patting it into the pan!
