Some do, some don't. There have been many interesting and delicious things at the M&G's that I've attended. Although many like to bring their specialty or something unusual, it is not always practical so each brings what they can. It is nothing to stress out about.
Your camping situation would generally limit your choices for example someone with a one burner stove would be hard pressed to bring fresh baked cookies, while this would be relatively easy for someone in an RV if they desired to.
Since I am a minimalist on the playa and bring no cookware or even a heat source, I generally contribute booze.
Everything Figjam said and more - barbequed ribs, fresh snow cones (topped with syrup or booze), fresh cookies, ice cream, alcoholic drinks that tasted like pineapple upside down cake flash frozen into pops, dozens of types of booze. The sky is the limit and those who can often go all out.
