Pour the Wilton S'more candy melts into a microwave safe dish. Heat in 30 second increments until completely melted. This takes about 2-2.5 minutes in my microwave.
Pour the melted chocolate over the top of the cereal (see photo). Using a large spoon, stir the chocolate and cereal together to evenly coat the cereal.
Add the 2 cups of powdered sugar to the resealable bags, 1 cup of powdered sugar in each.
Pour the chocolate cereal into the bags. Seal the bags and shake to completely coat the cereal with powdered sugar.
Allow the mixture to cool and then add in the chocolate chips (optional). Store in an airtight container.
