Melt butter in a big pot on low heat. Do not let it scorch.
Add a 10 oz bag of marshmallows. Hint - small ones melt faster!
Stir and stir again. Watch the heat and make sure you don't brown the butter or marshmallows.
Add 6 cups of Cheerios. Remove from heat.
Stir to thoroughly coat the Cheerios with the marshmallows.
Dump into a 11 x 13 dish which has been treated with a non-stick spray or lined with parchment paper.
Melt about ½ cup of chocolate in a microwave safe bowl (20 seconds at a time then stir - repeat until chocolate is smooth)
Pour chocolate into a small plastic baggie and make a tiny cut at the corner. Drizzle over your Cheerio marshmallow treats.
Cut while still warm but not hot.

Helpful Tip
Marshmallows make this mixture STICKY! Spray the back of a large spoon or spatula with nonstick spray. It will make flattening the cereal mixture much easier.Other cereal treats.Apple Jacks applesSpecial K cereal bars
