To make the Triple Garlic Sauce, set about a clove's worth of minced garlic aside. Then add the rest to a frying pan with about half of the vegetable oil. Put the pan over medium-low heat and slowly fry the garlic until it's light brown in color and very fragrant. Be careful not to burn it. Let this cool.
Add the remaining oil, black garlic, soy sauce, nutritional yeast, toasted sesame oil, and onion powder to a beaker or bowl of a blender/food processor. When the fried garlic has cooled, add it in with the other ingredients along with the oil. Blend the mixture until smooth.
To make the garlic noodles, boil the noodles according to the package directions. Transfer the noodles directly to a bowl using tongs or chopsticks, reserving the boiling liquid.
Add a few large spoonfuls of Triple Garlic Sauce onto the noodles and a ladleful of the boiling liquid from the noodles.
Toss together to emulsify the water with the sauce and coat the noodles. Taste and add more sauce if needed. If the noodles start to stick together, just add some more boiling liquid.
Garnish the garlic noodles with chopped scallions and freshly cracked black pepper.
