Cheerio Treats

I love fancy desserts, don't get me wrong, but there's something about a simple, quick, and yummy treat.
My mom used to make Cheerio treats when I was a kid and I haven't had these in years before randomly remembering them a few days ago. Naturally, I had to make them ASAP.
They're just as good as I remember... the chewy-ness of the marshmallow and peanut butter flavor plus the crunchy-sweetness of the cheerios make for such a yummy dessert.
Best of all, I guarantee your kids (if you have em) will love these, as long as you don't eat them all first. That's what I would do.

Ingredients:
5 cups Honey Nut Cheerios (I used a combo of Honey Nut and regular to cut down the sweetness)
1 package (aprox 6 cups) miniature marshmallows
1/2 cup smooth peanut butter
3 tablespoons butter

Directions:
Grease pan (I used 13x9 but an 8x8 would make thicker bars)
Put butter, marshmallows, and peanut butter in a large microwave-safe bowl. Heat in microwave (at full power) for 2 minutes.
Stir until marshmallow is smooth and ingredients are well-mixed.
Add cheerios, mix well to coat cereal.
Press mixture into pan (I find a rubber spatula helps a bunch with this, the mixture is sticky!)
Let cool, cut into bars, and enjoy!
