Once when I was a kid, my family went back to Mobile to visit relatives. We stayed the weekend at my aunt's house.
The first morning there, my cousins had this for breakfast. It was their new favorite cereal. I was a die-hard Peanut Butter Cap'n Crunch man, myself, and didn't really want to eat the Donutz, but it was that or cream of wheat.
It was horribly, horribly sweet and the real powdered sugar did an unholy thing to the milk. I had heartburn the rest of the day and kept urping up a sickly-sweet ooze.
