The hosts explore the history and cultural impact of Pop-Tarts, tracing their origins from the Kellogg brothers' Battle Creek Sanitarium through the cereal wars between Kellogg's and Post to the invention of the toaster pastry. They detail how Pop-Tarts were rapidly developed in response to a competitor's idea, how the product evolved in flavor, form, and marketing, and how it became an iconic but nutritionally dubious, ultra-processed food. The episode also covers fire hazards, lawsuits, international ingredient differences, and the nostalgic pull Pop-Tarts still have for adults.
