Hear me out, so one day we had lunch at work and I'm one of those folks that don't care if their food touches... noticed a lil green on my cookie, still ate it cus im a gremlin. And boy I tell ya!!!! So heres the thing... the guac has to be like a seasoned one, like kinda salty, but not too salty if that makes sense. Because it gives it a sweet and salty type of vibe which I think is why I like them. Also I tend to like it better with thicker cookies less gooey cookies (although flat and gooey is superior)
p.s: sugar cookies smack wit guac.
