1. In a large saucepan, melt the butter over low heat. Be patient and let it melt slowly to avoid burning.
2. Add the mini marshmallows to the melted butter, stirring constantly until they are fully melted and blended together. This should take about 2-3 minutes.
3. Remove the saucepan from the heat and stir in the chocolate chips, vanilla extract, and a pinch of salt until the chocolate is completely melted and the mixture is smooth.
4. Gently fold in the Rice Krispies cereal, ensuring each piece is evenly coated with the marshmallow-chocolate mixture. This is where my kids love to jump in and help!
5. Press the mixture into a greased 9×13 inch pan using a buttered spatula or wax paper. You want to press firmly but not crush the cereal.
6. Allow the mixture to cool at room temperature for about 20 minutes, then cut into squares and enjoy!

These steps are straightforward enough to whip up a batch even on the busiest days, because who has time for complicated recipes?
