Preheat oven 325 F. Prepare an 8-inch square pan with cooking spray.
To a food processor or blender, add the oats and process until smooth like a flour.
Add the remaining ingredients to the food processor omitting the chocolate chips. Process and combine until smooth.
Transfer the batter to a mixing bowl and fold in the chocolate chips reserving 1 1/2 tablespoons for the top of the batter.
Transfer the batter into the baking pan and bake at 325 F 25 minutes.
The bars should look a bit undercooked when you remove them from the oven, but they will finish cooking in the pan. Cool in the pan another 20 minutes before slicing into 12 bars.
