Great Glammas aka Helen McKinney's Famous Date Filled Oatmeal Cookie Sandwiches

My mom is Helen McKinney and this is her scrumptious recipe for Date Filled Oatmeal Cookie Sandwiches which I did not like at all until I grew up. I have renamed them Great Glammas as she is William's Great Grandma and a very Glamorous Great Grandma. As this is her cookie all decked out in 24K gold, it seemed more than fitting.
