1. Prepare a 9x13 dish by buttering or misting with cooking spray (we like coconut oil spray).
2. Melt the butter in a large pot.
3. Stir in the marshmallows and stir with a silicone spatula until melted.
4. Working quickly, add the cereal and stir to combine fully with the melted marshmallow mixture. Transfer to your prepared dish. Gently press into an even layer.
5. Allow the bars to sit for 5 to 10 minutes. Slice and serve!
Notes
Gently press the bars down using wax paper or clean wet hands to help keep the marshmallows from sticking.Be sure not to press too hard.
