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 ½ , 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!
