First, start by melting a stick of butter over medium-low heat in a large pot.
Then, add in half the bag of mini marshmallows. That's about 5 ounces of mini marshmallows.
Mix those two ingredients together over the heat.
Then, add 7 cups of pumpkin cheerios.
Also, add in the rest of the bag of mini marshmallows, which is another 5 ounces.
Mix all of these ingredients together until they are gooey.
Add the mixture into a 9x13 baking dish covered in parchment paper.
Then, refrigerate the treats for at least thirty minutes and enjoy.
