01 - Preheat the oven to 325°F (160°C) and lightly grease a 6-cup muffin tin or silicone egg bite mold.
02 - In a medium mixing bowl, whisk together eggs, whole milk, soy sauce, toasted sesame oil, mirin if using, garlic powder, and ground white pepper until the mixture is homogeneous.
03 - Fold in chopped ramen noodles, chopped scallions, finely chopped nori, and shredded cheese as preferred, ensuring even distribution throughout the mixture.
04 - Divide the prepared mixture evenly among the muffin cups, filling each approximately three-quarters full.
05 - Place the filled muffin tin into a larger baking dish, then pour hot water into the dish until it reaches halfway up the sides of the muffin tin to maintain moisture during baking.
06 - Transfer to the oven and bake for 18 to 20 minutes until the egg bites are just set and gently puffed.
07 - Remove egg bites from the oven and allow to cool for 5 minutes. Carefully run a knife around the edges to help release them from the tin.
08 - Sprinkle with toasted sesame seeds and extra sliced scallions before serving warm or at room temperature.
