Instructions

1. Coat a 9×13 pan with a little bit of butter.
2. In a large bowl, measure out 9 cups of Rice Krispies cereal; set aside.
3. In a large saucepan, melt butter over medium-low heat. After 5 minutes or so, the butter will start to foam and turn a golden brown. It will bubble and crack. Keep a close eye on it as it can burn easily. Cut the vanilla bean in half, and scrape the seeds with the back of a knife. Add the vanilla to the melting butter.
4. When the butter is nice and brown, add the marshmallows. Stir over low heat until marshmallows are 90% melted. I like it when not all the marshmallows are melted. Pour the marshmallow mixture over the Rice Krispies and stir to coat evenly.
5. Press the treats into the prepared 9×13 pan. Let sit for 2 hours at room temperature before cutting into 20 or 24 squares.
6. Devour.
