Traditional Bountiful Cake (Stedrak with healthier ingredients)

Living in a cold climate, my ancestors used ingredients which were available in the season. Before the inhospitable winter came, nature provided them with nuts, plums, apples and honey. Everything had to be processed, stored or dried before the cold hit. Maybe this version of Bountiful Cake isn't very local (there are no almond trees, nor have we coconut palms growing in our region) but it is at least healthier than the original version.
