Add unsalted walnuts, nutritional yeast, garlic powder, and salt to a blender or a food processor and pulse for 30 seconds. Pulse, open, shake, and repeat. Stop before you think you should; otherwise, it can become oily clumps.
Taste and adjust flavor. Add more nutritional yeast for “cheesiness” and extra garlic powder for a more intense note.
Store in a covered container in the refrigerator for up to 3 weeks.

Notes
It's essential to stop, stir (or shake) and repeat; otherwise, it can turn into clumps and may not have the powdery texture we are looking for.If using a nutribullet(affiliate link), stop when I have mostly powder with a couple of walnut pieces left. A couple of walnut pieces are great. :)
