Combine the two cake mixes into a gallon-size ziplock bag labeled with directions. Include a measuring spoon, bags of snack size chocolate bars, and a bottle of chocolate/caramel syrup. If the care package is international, include microwave safe paper cups. If the care package is domestic, add either a can of non-stick spray (for use with a ceramic mug) or microwave safe paper cups. Don’t forget to include the “recipe”.
