add butter, peanut butter, marshmallow creme & regular marshmallows into a large pot, once the marshmallows start to slightly melt add in cereal and turn off coat generously. Now add in chips and stir add to casserole and pat down, I added a few more peanut butter cereal balls to top for topping. put in fridge at least 30-45 minutes or you can leave on counter to set up. your treats will still be ooeygooey but easier to cut.
