A delightful twist on a classic treat, combining the creamy richness of peanut butter with the gooey sweetness of marshmallows.
Melt the butter in a double boiler over low heat.
Using a double boiler prevents the butter from burning.
Add the peanut butter and marshmallows to the melted butter, stirring until completely smooth.
Stir constantly to ensure even melting and prevent sticking.
Remove the mixture from heat and fold in the rice cereal until evenly coated.
Work quickly as the mixture will start to set as it cools.
Transfer the mixture into a greased 9x13 pan and press down firmly to create an even layer.
Use a spatula or the back of a spoon to press the mixture firmly.
Allow the bars to cool completely at room temperature or refrigerate until set.
Refrigerating helps the bars firm up faster for easier cutting.
Cut into squares and serve.
Use a sharp knife for clean cuts and wipe the blade between slices.
