Heat milk for the dough. Crumble yeast into it. Mix flour and sugar. Knead the egg and yeast milk with the dough hooks of the mixer for about 3 minutes to a smooth dough, kneading 50 g butter in flakes.
Cover and leave in a warm place for about 1 hour until the volume has doubled.
Line a springform pan (28 cm Ø) with a large sheet of baking paper. Pour in the dough and spread it with a moistened spoon. Cover and let rise for about 30 minutes.
Preheat oven (electric cooker: 200 °C/circulating air: 175 °C/gas: see manufacturer). For the honey icing, briefly boil 100 g butter and honey with the nuts. Spread on the risen dough. Bake in a hot oven for 15-20 minutes.
Remove and let it cool down.
For the vanilla-honey-cream mix pudding powder with approx. 5 tablespoons milk and honey. Bring the rest of the milk to the boil, remove from the stove. Stir in the pudding powder. Simmer for about 1 minute while stirring. Let it cool down for about 5 minutes, then stir in butter by the spoonful.
Remove the cake from the mould and paper. Cut open horizontally. Stir the cream briefly. Spread on the cake base, leaving 1-2 cm of edge free. Carefully place the cake lid on top. Chill for about 15 minutes.
