hjónabands​sæla (wedded bliss cake)

Friends and their random knowledge are awesome!  It's how I learned about this Icelandic treat, hjónabands​sæla, that is basically a double crumble (crumble on bottom + crumble on top) with rhurbab jam in the middle.  As you might suppose, it is ridiculously sweet and rich!  I would say that coffee is a necessary compliment.

And, for the record, I veganized this recipe.
