Add in the marshmallows and stir until they are almost melted.
Remove from heat and add in peppermint extract and pinch of salt..

Notes
Can I melt the marshmallows in the microwave instead?Melt butter in microwave-safe bowl first. Add marshmallows into bowl with melted butter and heat on med-high power in 15 second intervals, stirring between cycles until marshmallows are almost totally melted.What’s the easiest way to cut Rice Krispie treats?I like to use a serrated knife for a clean cut. Cut them into 20 squares or any shape you like.
