"This is the plum cake or tart that my Grossmutter made. It is delicious, and any fruit can be substituted for the plums. Therefore it is a seasonally great! It’s a Southern German dessert from the Zweibrucken area. My daughter requested this for her ‘birthday cake’ when she turned 7; it was a hit at her party! Top with whipped cream. My personal favorite version is to alternate plum and nectarine slices."
