Let me tell you: There were few things more satisfying than a Carnation Breakfast Bar and a tall glass of ice-cold milk. A friend of mine used to joke they were essentially Snickers bars with vitamins sprayed on, but he was wrong. They were more like Whatchamacallit bars with vitamins sprayed on: oats, chopped nuts, and perhaps some puffed rice (and chocolate chips in the chocolate chip flavor), bound together with a touch of corn syrup and surrounded by chocolate.
And yes, I’m also serious about the Hires Root Beer. Though Dr Pepper Snapple has this page for the product, good luck finding it in your local supermarket.
