Boil 675 ml of milk. Stir pudding powder, 90 g sugar and 75 ml milk until smooth. Stir into the boiling milk, bring to the boil and simmer for about 1 minute. Remove from the heat, pour into a bowl and cover with foil.
Allow the pudding to cool, then chill for at least 2 hours, preferably overnight.
Melt the butter. Add 225 ml milk, warm up lukewarm. Mix yeast, 1 tablespoon sugar and 100 ml of the milk mixture. Mix flour, salt and 75 g sugar in a bowl, press a depression in the middle.
Pour yeast milk into the hollow, mix with some flour from the rim and cover with flour. Cover and leave to rise for about 15 minutes.
Add the remaining milk mixture and egg and knead with the dough hooks of the hand mixer to a smooth dough. Cover the dough and let it rise in a warm place for about 30 minutes.
Peel and quarter the pears and remove the core. Cut the quarter into cubes. Cut the dough in half. Roll out each half successively in a rectangle (approx. 25 x 36 cm). Spread half of the pudding on each half.
Spread pears on top. Roll up starting from the long side. Cut into slices of about 3 cm and place them on a greased, floured baking tray (27 x 29 cm). Cover and leave to rise in a warm place for about 5 minutes.
Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 30 minutes. Take out and let cool down.
