Pre-heat oven to 350 degrees.
Line an 8X8 baking pan with parchment paper.
Add the oats to a food processor and blend until floured, about 7-10 seconds.

Add mixture into pan and smooth into an even layer.
Bake for 35 to 45 minutes, until edges being to brown very slightly. These bars will be soft and chewy and they wont brown much at all - if they're browning a lot, they're burning!
