For the dough, warm the milk lukewarm and remove from the stove. Crumble the yeast into it and dissolve it. Knead flour, 2 tablespoons sugar, egg and yeast milk with the dough hooks of the mixer for about 3 minutes to a smooth dough, kneading 50 g butter into it. Cover and leave to rise in a warm place for about 1 hour until the volume has doubled.
Preheat oven (electric cooker: 180 °C/circulating air: 160 °C/gas: see manufacturer). Line a baking tray with baking paper. For the icing, briefly bring 100 g butter, 2 tbsp. sugar, honey and nuts to the boil and allow to cool slightly.
Divide the dough into 12 pieces and form them into balls. Spread them on the tray and press them flatter. Spread the icing on the dough balls. Bake in a hot oven for about 15 minutes. Let it cool down.
Wash plums, halve, stone and cut into thin slices. Mix cinnamon and 2 tablespoons of sugar. Whip the cream until stiff, pouring in the cinnamon sugar. Cut the bee sting particles in half horizontally. Fill with cream and plums and serve immediately.
