In a bowl mix the milk with the sugar and yeast and let it start bubbling slightly
Add the rest of the ingredients and knead for 2 minutes until somewhat smooth
Place in a buttered or oiled bowl, cover and let rise for 2 hours in a warm place
Make the filling by mixing the butter with the powdered sugar
Preheat your oven to 180°C
When the dough has doubled, punch it down and place on a floured surface
Divide into 12 equal pieces, roll each into a ball
Roll each piece into a rectangle, smear with the filling and sprinkle with poppy seeds
Next, roll into a log, cut in half, braid and knot, just like making a Babka
Place each bun on a parchment covered sheet pan and let rise for 20 minutes before baking
Bake in the oven for 15 minutes, then take out
Cover the pan and the buns with foil and bake for 20 minutes
Remove from the oven and let cool
Meanwhile make the glaze
Add 50 g of the milk to the white chocolate and 100 g to the dark chocolate
Melt each in a water bath, double boiler
Once the buns have cooled, dip into the dark chocolate and place on a wire rack to set
After 10 minutes take a spoon or a spatula and drip the white chocolate over the buns
