Mix the yeast with the milk and sugar and set aside for 10 minutes.
Add the flour, egg, salt, and butter – knead into a smooth dough.
Let rise for 1 hour. Divide the dough into 8-10 pieces, flatten them, and fill each with jam or Nutella. Form the rolls and place them in an air fryer basket lined with baking paper. Brush the tops with the egg wash and milk. Bake at 160°C for 10-15 minutes.
