Pop-Tarts originally came in four flavors: apple currant, strawberry, blueberry and brown sugar cinnamon. As of 2015, these Kellogg’s breakfast pastries were available in nearly 30 flavors in the United States, ranging from the traditional to the truly strange. Confetti Cupcake Pop-Tart, anyone?
Most varieties of Pop-Tarts are topped with a layer of frosting covered in colorful sprinkles or a swirl of icing, but the original product was unfrosted. The original pastries also featured a diagonal cut so that consumers could easily break the Pop-Tart into two pieces.
Despite the limited flavors, Pop-Tarts were wildly popular when they debuted in 1964. The first supply of Pop-Tarts sold out in two weeks, leaving consumers empty-handed until the next shipment could be sent to grocery stores across the country. As for those who might have been waiting for a frosted variety, that wish was granted in 1967.
