For the vanilla snails, make a smooth dough with butter, milk, flour, sugar, yeast and egg. Let the dough rise until it has doubled in volume.
Knead the dough again well by hand and roll it out.
For the filling, melt butter and stir with powdered sugar and vanilla pudding powder until smooth and free of lumps, mix in raisins and spread the pudding on the dough.
Roll up the dough and cut each into pieces about 3 cm thick. Place these on a baking sheet and flatten slightly. Brush with milk and bake the vanilla snails at 180 °C top/bottom heat for approx. 20 minutes.
