In a large pot, melt your butter on low. Once your butter is melted add in the marshmallow fluff and stir well over low heat (image 1). Stir slow and on low until well combined.

Once the marshmallow fluff is melted in, turn the heat off and stir in the vanilla extract. Pour the mixture over your rice cereal (image 2). Stir it together (image 3).

Gently press it into a well greased 8 x 8 pan (image 4). Cool for at least 2 hours before cutting and serving

Reduce the heat before adding your vanilla extract in.
