For this recipe you will need Rice Krispies Cereal, Mini Marshmallows, Butter, and Vanilla Extract.
In a saucepan over low heat, melt the butter. While the butter is melting, measure one cup of marshmallows and set aside.
Remove the mixture from the heat and stir in the vanilla extract.
In a large bowl, pour the marshmallow mixture over the Rice Krispies cereal.
Use a large silicone spatula to mix together the marshmallow mixture and the Rice Krispies cerea.
Add the reserved 1 cup of marshmallows to the mixture and gently fold in.
Gently press the Rice Krispies mixture into a 9x13 pan lined with parchment paper or sprayed with cooking spray.
Allow the treats to cool and then cut into squares. Enjoy!
