optional: strawberry flavored candy (I used strawberry sour balls)
Place cereal in a large bowl. Whisk together jello pudding mixes in a small bowl.
In a microwave safe bowl, melt chocolate chips. (Microwave for 1 minute on half powder, then microwave 20 seconds at a time, stirring after each interval until smooth). Pour chocolate over chex cereal. Use a large spoon or a rubber spatula to toss cereal with chocolate until well coated. Transfer chocolate coated cereal to a large zip lock bag.
Pour dry pudding powder into bag. Seal and toss until well coated. Open bag, add powdered sugar, seal bag and toss to coat. Add graham crackers and optional candies. Store in airtight container.
