Grab some butter or some non-stick cooking spray and grease your spatula and pan well.
Toss 4 tbs of butter and 16 oz of marshmallows into a bowl.
Heat in the microwave for 30 - 60 seconds.
After heating, stir the butter and marshmallows together.
Heat for another 30 seconds and then stir.
Repeat the stirring and the heating until your marshmallows are well mixed and melted.

Slowly mix in 7 cups of corn pops with your melted marshmallows.
Transfer your cereal and marshmallow mixture from your bowl into your greased pan.
Use your greased spatula to gently press the mixture into your pan.
