Gifts - brownie mix in a jar

I have made up several of these brownie mix in a jar for a few of the guys in our family.  With the directions attached they can make up their own snacks or dessert for a family meal any day of the week!!  It would be nice to have a few of these gifts on hand for any last minute occasion.   I have packaged them in peanut butter jars that I have saved over the year.  Therese
