Rice Krispies are an iconic treat, but making them with marshmallow fluff is a fun twist on a classic. You're going to love making these rice Krispie treats! They're soft, gooey, and oh-so-perfect in every square.
Grease the inside of an 8x8 baking dish with softened butter and set aside.
Add your butter to a large pot over medium-low heat. Cook until melted.
Add in the marshmallow fluff by using a rubber spatula to scrape the inside of the jar as best as you can.
Stir until the fluff seems fully incorporated and softened.
Remove the pot from the heat.
Stir in the rice crispy cereal until fully coated.
Transfer the cereal mixture to the prepared baking dish and use greased hands or a spatula to press down on the cereal and compact it into the dish. It helps when using something butter coated as the cereal is less likely to stick to butter.
Allow the cereal to cool and set for an hour or two before slicing and serving.
