I would say an ee. Not all easter eggers have muffs tufts or beards. Many are cleanfaced. How old is it? I would think it might be and EE mixed with something.
Thank you for saying that not all EE have muffs or tufts or beards. I have several that do not. She looks almost exactly like a pullet I hatched out a few years back, that was "pure" EE. Look at this pic on feathersite. scroll down to the middle of the page.
You won't know what color egg it will be until she lays. She may have the blue/green/olive eggs or maybe just a pink one. (i don't like the pinkish ones)
