Knead the dough ingredients, cover and chill for about 2 hours. Mix the ingredients for the filling, chill.
Roll out the dough between two cut freezer bags into a rectangle (20 x 30 cm). Put the filling on top and smooth out evenly. Roll up the long side like a roulade and cover or wrap in foil and put in the fridge overnight.
Cut the roll in portions into about 1/2 cm thick slices, place on a baking sheet lined with baking paper and bake at 180 ° C for about 10-12 minutes.
