Grandma's Christmas Cookies

My grandma's chocolate-molasses cutouts were always my favorite Christmas cookie.
My mom sent me a photo of the recipe from an old family cookbook, 
and I decided to post it here so I can pin it and have it easily accessible.
The family cookbook credits these as "Aunt Ethel's Chocolate Jumbles"
but to me, they'll forever be "Grandma's Christmas Cookies".
