Mix butter, poppy seeds, sugar and rum and chill. De-stem the cherries, cut them in half and remove the stone. Unroll yeast dough, remove paper. Place the dough on a baking tray lined with baking paper. Fold the dough over lengthwise once in the middle
Fold over the edges to form an oval. Press the edge slightly. Press in holes with your finger or with the help of a wooden spoon handle. Fill the holes alternately with the poppy seed butter (in small flakes) and the cherry halves. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 25-30 minutes. Remove, dust the edge with icing sugar and serve preferably warm. Whipped cream tastes good with it
