Place the dough side by side and allow to thaw. Wash, clean, halve and stone the plums. Cut halves into slices. Bring to the boil with 50 g sugar over medium heat while stirring and let it boil down for 6-8 minutes.
Remove from the heat and let it cool down.
Place the dough sheets on top of each other. Mix 2 tablespoons sugar and decorating sugar. Spread the sugar mixture halfway on the work surface. Place the dough on top, spread the remaining sugar mixture on the dough. Roll out to a square (approx. 20 x 20 cm).
Quarter the dough to make four squares (approx. 10 x 10 cm).
Place on a baking tray lined with baking paper and spread plum compote in the middle of the dough. Sprinkle with almonds. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for 20-25 minutes.
Remove and serve lukewarm. Vanilla ice cream tastes good with it.
