Lay out a large sheet of wax paper on a table or countertop and lightly spray it with cooking spray.
Place the popped popcorn in a very large bowl.
Melt the almond bark and peanut butter together slowly in a double boiler or in the microwave in 30-second increments, stirring until smooth.
Pour the almond bark mixture over the popcorn.
Add the peanuts and Rice Krispies, then stir for a couple of minutes until everything is well coated. Be gentle so you do not crush the popcorn.
Spread the popcorn mixture over the prepared wax paper.
Let it dry for at least 1 hour.
Once the coating has hardened, break the popcorn crunch into chunks and serve.
Notes
This makes more than 14 cups once the cereal, peanuts, and coating are added.Do not use buttered microwave popcorn because the flavoring can make the coating greasy.Let the popcorn crunch dry fully before bagging it for gifts.
