If you put the guacamole as one of the lower layers, it won't brown. You just need to reduce the air contact with it.

Guacamole does not last long at all. Since it is made out of avacadoes, it turns brown if not eaten within a few hours after being made. If you want to preserve it, try squeezing lime juice on it, or also covering it with lettuce or something. It's actually usually the top of the guacamole that only goes bad at first because of the oxygen hitting it. So somtimes when just the surface of the guacamole is brown, you can mix it together with the rest of the green guacamole - unless it's obviously rotten.
Guacamole is great in and on so many things! Even kids can love them! www.cooks.com and www.foodnetwork.com have great, authentic guacamole recipes. They are easily adjusted to each spice level!
To me, spoiled guacamole tasted a little sour at first, then a significant tingle on the tongue. This had not turned brown. It was in a sealed plastic container that went unused for too long.
The main ingredient of guacamole is ripe avocado. All you really need to make guacamole are avocados and salt. However you can also add lemon/lime juice, chopped cilantro, chiles, onion and tomato to taste.
