Add everything except the chickpeas, oats and chocolate chips to the bowl of a food processor. Blend on high for one minute until combined and creamy.
Add the beans and process for a minute then remove the lid and scrape down the edges. Process for an additional minute then pause to scrape the edges again. Repeat 1-2 additional times until smooth and creamy.
Add the oatmeal and puree for 1-2 minutes. The oats should be mostly incorporated and finer but still have some slight texture.Add the egg until just combined. Stir in the chocolate chips (or another add in).
Scoop 2 tablespoons of batter at a time onto a lined baking sheet. (The batter will be a bit runny and sticky- somewhere between muffin batter and cookie batter).
Bake at 350 °F for 10-12 minutes until the cookies appear set but are still soft to the touch. Remove from the oven and allow to cool on the baking sheet for 5 minutes before removing to a wire rack to cool completely.
