Sadie Lebo's Famous Coconut Cake!

Sadie Lebo and I aren't related, but she was a dear, dear woman I met through our many trips to the now-defunct Reinholds Athletic Club. She was a waitress there and she and her husband, Popeye, were great people.
This cake was famous throughout the area and no one could ever hope to duplicate it.
Thanks to Sadie's daughter-in-law, Janet Miller for sharing it with me. When I was a Charge Nurse at the Denver Nursing Home, Janet's father was a patient there. I asked her about the recipe and she not only got it for me, she handed it to me, in Sadie's handwriting! I value this as I do my own grandmother's recipes. Thank you Janet, and thank you Sadie.
