Gather all ingredients before you start. Slice the green onions, chop the cilantro if using, and keep the garnishes ready so the noodles can be served while warm.

Cook the knife-cut noodles according to the package directions until tender and chewy. Before draining, reserve 4 to 6 tbsp of the hot noodle cooking water.

In a large mixing bowl, whisk together the chili oil, peanut butter, soy sauce, black vinegar, sugar, and optional sesame oil. Add 4 tbsp of hot noodle water and whisk until smooth, adding more water 1 tbsp at a time if the sauce is too thick.

Add the drained noodles to the bowl and toss until evenly coated in the creamy sauce. Finish with green onions, cilantro, and sesame seeds, then serve immediately.
