I guess I had s'mores on the brain after writing about them yesterday, since I was inspired to look up the record for the world's largest s'more. The Guinness Book of World Records lists a s'more made in 2003 as the largest. It was constructed in California from 20,000 marshmallows, 7,000 Hershey's chocolate bars, and 24,000 graham crackers. All totaled, it weighed about 1,600-lbs.
The Guinness category was retired, however, which means that an even larger s'more made this year went unrecorded!
The current largest s'more measured 1,936-sq feet and was constructed to celebrate the 70th anniversary of Virginia State Parks. It was made with 8,000 Hershey's chocolate bars, 40,000 marshmallows and 55,000 graham crackers - nearly double the size of the previous record holder, though it didn't use quite as much chocolate.
