Talk about the most delicious bar on the market

So... I eat these super slow so I can enjoy every delicious bite. The flakes of cereal are sooooooo good. I have to be careful because I will demolish an entire box. They make my mouth water just by thinking about them. Its like a huge peanut butter cake with fruity cereal treats in every bite!! I recommend these to everyone!!
