In a large mixing bowl combine 4 cups Leapin' Lemurs Cereal and 1 cup marshmallows. Stir to combine.
In a microwave safe bowl combine chocolate chips, butter and peanut butter.
Microwave in 30 second intervals, stirring between until chocolate chips and butter are melted and you have a chocolate peanut butter sauce.
Pour melted chocolate peanut butter mixture over your marshmallow cereal mix. Fold gently until all cereal is covered in chocolate and peanut butter.
Sprinkle powdered sugar over cereal mix and fold gently until powdered sugar is coating your cereal mix. Spread on a baking sheet lined with parchment paper to cool, roughly 15-20 minutes.
Once your cereal mix has cooled, add remaining Leapin' Lemurs Cereal, 1 cup of marshmallows and pretzels, candy coated chocolate and cashews.
Toss and serve! Store leftovers in an airtight container!
