01 - Cook noodles according to package directions until al dente. Drain thoroughly, reserving 1/4 cup pasta water. Set aside.
02 - Heat butter and olive oil in a large skillet or wok over medium heat until melted. Add minced garlic and cook, stirring constantly, for 1-2 minutes until fragrant and golden but not browned.
03 - Reduce heat to low. Add soy sauce, oyster sauce, brown sugar, and black pepper. Stir continuously until sugar dissolves and sauce is well combined, about 30 seconds.
04 - Add cooked noodles to the skillet. Toss vigorously with tongs or wooden spoon until evenly coated in sauce. Add reserved pasta water, 1 tablespoon at a time, if needed to achieve silky consistency.
05 - Remove from heat immediately. Top with scallions, Parmesan cheese, and toasted sesame seeds as desired. Serve hot while aromatic.
