Place cashews, rolled oats, salt, and cinnamon into the processor. Chop the ingredients until you have a fine mixture, but don’t chop them for so long that you make cashew butter.
Blend in the maple syrup and vanilla extract. Beware: This step can be hard on a low-powered food processor. If the mixture is too dry for your tastes, add more syrup; if it’s too gooey, add more cashews or oats, and use less maple syrup next time.
Depending on the size of your batch, stir in the chocolate chips by hand, or put all ingredients into a mixer.
