INFORMATION ABOUT BROWNIES IN A JAR
This is the link for the brownies, there is a list of 9 various recipes for "brownies in a jar".  The only problem I see is that all the recipes call for either or all eggs, oil, milk.  That's good for the states, but what about Iraq or Afganistan?

However - I have been urged not to send the "brownies in a jar" to Iraq - the heat will cause a fast growth in bacteria, also this was mentioned on www.military.com.

A warning also from Joe & Chris - There has been some information, as well as an official request from the Military, NOT to send brownies in a jar - they may not bake at suffienctly high temperatures to kill the bacteria.
