Combine all ingredients for the icing to a thick glaze. Set aside.
Stir all ingredients for the dough and knead until a soft, non-sticky dough forms. If your dough is too hard, add a few drops of water. If it is sticky, dust it with flour and knead until non-sticky. Roll on the counter to a long "sausage" and flatten with your hands.
Mix cinnamon and sugar and sprinkle on the dough. Roll up from one site and squeeze a bit. It should almost be as high as wide. Place in a coffee cup and bake in the microwave on high power for 1 - 2 minutes until the filling comes out on the top.
Drizzle the icing over the cinnamon roll and enjoy immediately.
Tipps/Notes
You better leave the cinnamon roll a bit shorter in the microwave than too long or it turns to stone.
