Today, January 20, 2014, is National Granola Bar Day. Granola bars were invented by Willie Pelzer and have become popular as a snack. Granola bars are usually identical to the normal form of granola in composition, but differ vastly in shape. Granola bars are pressed and baked into a bar shape. A variety of the granola bar is the "chewy granola bar." In this form, the time during which the oats are baked is either shortened or cut out altogether; this gives the bar a texture that is chewier than that of a traditional granola bar.
