Wash, pit, and quarter the Italian plums. Spread them out on a parchment-lined baking sheet.
Optionally, sprinkle the plums with sugar. This gives the Powidl a subtle caramelized flavor.
Bake at 140°C (285°F) convection / 160°C (320°F) conventional oven for 3–4 hours. Stir every 30–60 minutes to prevent the plums around the edges from burning.
Scrape the finished Powidl from the baking sheet.The Powidl is ready when the plums have cooked down into a dark, almost black or deep purple, thick and slightly firm, sticky mixture, but are not burnt.
Transfer the Powidl to a saucepan and simmer for about 5 minutes with the apple juice, rum, vanilla sugar, and cinnamon.
While still hot, transfer the Powidl into sterilized canning jars using a jam funnel. Seal with sterilized lids.
