In a small bowl, whisk together warm milk, instant yeast, and sugar. Let it sit for 5 minutes until it turns slightly foamy.
Add flour, salt, and butter to the mixture. Mix and knead until a smooth dough ball forms.
Cover and let it rest for 30-40 minutes (or until slightly puffy).
In a bowl, mix together brown sugar, melted butter, and cinnamon to make the cinnamon filling.
In another bowl, whisk cream cheese and sugar until smooth for the frosting. Set aside.
Roll out the dough into a thin rectangle on a floured surface.
Spread the cinnamon sugar filling evenly over the dough.
Using a sharp knife or pizza cutter, cut the dough into thin strips.
Roll each strip tightly to form mini cinnamon rolls.
Place the rolls in a greased baking dish.
Brush the tops with a little cream to keep them soft.
Air-fry at 170°C (340°F) for 10 minutes, or bake in a preheated oven at 180°C (350°F) for 12-15 minutes until golden.
Once baked, generously spread the cream cheese frosting over the warm rolls.
Serve immediately and enjoy the softest, most delicious mini cinnamon rolls ever!
