Pre-heat oven to 350 degrees.
Grease a muffin tin (regular or mini) REALLY well with butter spray or butter.
In a large bowl, vigorously whisk milk, oil, salt, and egg.
Slowly add flour, about a 1/4 to 1/2 a cup at a time and mix well until well combined.
Add cheese and mix.
Spoon mixture into muffin tin with the batter until almost all of the way, and then sprinkle with additional Parmesan cheese.
Bake at 350 degrees for 30-35 minutes until browned.
Remove from oven and then set to cool for at least 10 - 15 minutes. Enjoy!
