OG Puddin' / Creamy Puddin' by Trippy Drips was my absolute fav and ADV for about 8 years, and I've never been able to find anything as good since they closed. They were a small shop based in Illinois, with a line of about 15 or so consistently great dependable flavors available for online ordering until late 2023 when they became a casualty of FDA threats. Can't seem to find anything quite like their Creamy Puddin' , which was a sort buttery vanilla pudding flavor with a slight hint of graham to it.
