Preheat the oven to 180 ° C. Grease the muffin tray (size 12) or use paper cases.
Chop up the white chocolate a little, put it in a small metal bowl and melt it with the milk in a water bath (simply hang a small bowl in a strainer and fix it in the pan). Let the mixture cool down a little.
Mix the flour and baking powder.
Mix the eggs with the creme fraiche, sugar, vanilla sugar and chocolate mass.
Quickly add the flour mixture and stir in. Pour the batter into the molds / muffin tin.
Bake the muffins in the oven (center) for 20 to 25 minutes. Let the muffins cool down a bit in the tray and then remove them from the tin.
