Cracking bit of pop-tart history here Chico :
Originally not frosted when first introduced, it was later proved that frosting could survive the toaster, and the first frosted Pop-Tarts were officially released in 1967. However, frosted Pop-Tarts are not suitable for vegetarians because they contain gelatin. Today, there is a wide variety of Pop-Tart flavors, including Chocolate Chip, S'Mores, Raspberry, French Toast and Mint Chocolate Chip.
In 1992, Pop-Tarts became the focus of controversy when Thomas Nangle sued Kellogg for damages after his Pop-Tart got stuck and caught fire in his toaster. The case gained notoriety when humor columnist Dave Barry wrote a column about starting a fire in his own toaster with Pop-Tarts. In 1994, Texas A&M University professor Joseph Delgado performed an experiment proving that, when left in the toaster too long, strawberry Pop-Tarts could produce flames over a foot high. The discovery triggered a flurry of lawsuits. Since then, Pop-Tarts carry the warning: "Due to possible risk of fire, never leave your toasting appliance or microwave unattended."
