The Market, located at 1445 Larimar Street, Denver, Colorado makes this fabulous cake. We first had the cake at a birthday party for our friend (Mary). It was so good that I had to search for the recipe, and found it in an old Rocky Mountain News article. The RMN no longer publishes a newspaper, so I'm saving the recipe here.
As a child, my parents traveled quite a bit and a retired couple (Mr. and Mrs. Kern) would stay with us kids. I'm sure keeping 4 kids busy wasn't easy, and Mrs. Kern would make these no-bake treats for us. It's a simple-to-prepare recipe, one that Mrs. Kern allowed us to help make — we were in charge of rolling the date balls in coconut.
A co-worker made this recipe for a cookie swap years ago, and they have been one of my favorite holiday cookies ever since then. I haven't tried it, but freezing the peppermint patties might make it easier to shape the dough around the them.
