We have a classroom party coming up Wednesday at our nut-free school. This smore bag is a great and easy snack to share with everyone. 
I don’t have real measurements, just use a giant bowl, combine and add to small school safe kiddo bags for snacking. 
Approx: for 30 small bags

• 3 family size boxes chex plain cereal 18oz
• 4 bags enjoy life mini chocolate chips
• 4 bags mini marshmallows

1. Mix together in a bowl
2. Chocolate sinks, so fluff often
3. Three handfulls, or about 1.5 cups of mix per bag.
