How to make marshmallow and oats bars
Add 3 tablespoons of butter in a pan and heat it until it completely melts.
Add the marshmallows.
Make sure to use a bag of them because when they melt, their size will decrease.
Stir until the marshmallows become a dense liquid. If your marshmallows are white (like they usually are), after it becomes a liquid it will look like dense, thick milk.
