Turn the dough out on a floured surface and roll it out to a large rectangle.
NOTE: if too sticky, add flour. Pay attention to the bottom of the dough, you do not want it sticking to the surface! Spread the filling over the rolled-out dough, using a spatula. Fold the dough in half lengthways. Using a pizza cutter, cut 16 strips widthways. Take one strip and carefully twist it then fold around your fingers into a knot. It doesn’t have to be perfect!
Place the buns spaced well apart on the baking sheets, cover with a kitchen cloth and let rise for 30 minutes. Preheat the oven to 400F, brush each bun with half the beaten egg, sprinkle some sugar (or whatever you like), then bake for 10 minutes or until golden brown!
