This is truly one of the best cakes I have ever made. A marzipan riff on basic streusel take this cake from rich to decadent. There is no traditional cake base. Pure marzipan streusel cradles the fresh elderberry mixture on top and bottom. This recipe is very easy to make if you already have marzipan on hand do not have to de-stem the elderberries (see method below).
The fresh elderberries can be hard to harvest if not already not de-stemmed. If you purchase them on the stem, the best way to separate them is to freeze them in a paper bag. When the berries have frozen, shake the bag and the berries should fall off them stems. Make sure you separate and discard all stems as they are poisonous.
