How to Make Marshmallow Treats From The 50S

Generously butter a 13 x 9 inch baking pan.
Melt 1/2 cup (1 stick) of unsalted butter in a microwave-safe bowl in 30 second intervals, stirring until completely melted. Alternatively, melt butter in a saucepan over medium-low heat on the stove.
Add 10 oz (about 4 cups) of miniature marshmallows to the melted butter. Stir constantly until completely melted and smooth.
Remove from heat (or microwave).
Gently stir in 5 cups of Rice Krispies cereal.
Press the mixture firmly and evenly into the prepared pan using a buttered spatula or wooden spoon.
Let sit for at least 1 hour to set completely. For easier cutting, chill for 2-3 hours.
(Optional) Add an extra cup of Rice Krispies for a less sugary treat.
