Boil noodles according to package directions.
In a bowl, add the green onion, garlic, red pepper flakes, chili powder, soy sauce, parmesan, brown sugar, and salt to taste. Set aside.
To a saucepan over medium-high heat, add the sesame oil, neutral oil, and butter. Heat the oils until very hot and sizzling.
Take off the heat and carefully pour over the bowl with the garlic, onion, and chili. It should bubble. Mix all together.
Add to the noodles and toss. Taste and adjust anything to your liking. Add the green onions and more parmesan in along with chili flakes if you want it more spicy.
Enjoy warm!
