I cooked this dish last night It turned out pretty good. Not the greatest thing, but the kids love it! Very kid friendly and something they could easily help with. I did mine on the stove since I have a small microwave. It was VERY simple and the flavor isn't bad. We added some of the easter candy we had left to the mix at the end. made it pretty interesting and colorful. (we used sixlets and about 7 rolo's) The rolos make for a carmelly surprise when you find one. :)

This is so easy and simple. A nice change from the usual rice cereal. I did a mix if regular and honey-nut oat cereal.

Quick and easy treat! I reduced the butter to 3 tablespoons and only used 1/4 cup peanut butter and it tasted great!

Wonderfully delicious! I made these because my son has diabetes and needs frequent snacks and has tired of all the "normal" snacks. Not only does my son love them but so does the rest of the family. Very very easy to make.

These are delicious and a nice change from Rice Krispie treats. My kids love them and I feel like it's a good snack because you get some protein and fiber along with your sugar. I followed the recipe exactly and wouldn't change a thing. Will definitely be making these again, thanks for sharing!

I was looking for something to satisfy my craving for peanut butter and cereal... I used Rice Krispies for the cereal - crunchy peanut butter and I only had big marshmallows. Also - I put a layer of peanut butter chocolate ganache on top - delish! My rice krispie was a little hard... not enough marshmallow? Not sure. But it was tasty!

These are easy to make and so yummy. I used chunky peanut butter and have also used M & M's.( The new pretzel kind were awesome.) I will make over & over!
