“Peach Cream And Filling” are a collection of AI-generated posts in which an absurdly old person (usually around 94-120, but occasionally more than several thousand years in age) claim to have “made their own birthday cake with peach cream and filling”. An example of a caption for these images:

“Hello everyone, I am 108 years old, I made my own birthday cake with peach cream and filling, I started decorating cakes from 5 years old, I love it, and I can’t wait to grow my baking journey 🥰💕❤️💗🦗”
