In a pot, over medium heat, melt butter.

Place Peanut Butter in the pot, and stif until incorporated with the marshmallow mixture.
Pour Peanut Butter/ Marshmallow mixture over top of the Rice Krispy Cereal in the bowl.
Mix until about halfway incorporated. Distribute spoonfulls of the marshmallow fluff overtop the mixture.
Finish mixing the Rice Krispy Treat Mix until all the Rice Krispies are coated. The more you mix, the smaller the pocketfulls of marshmallow fluff will be.
Place mixture into a 9″x13″ pan that is nonstick or lined with parchment paper and press down evenly over top. Making sure not to press down too much or the treats will become dense.
Let the Fluffernutter Krispy treats set for at least 2 hours before cutting into desired size!
