Combine chickpeas, red onion, and garlic in a food processor and process until a thick, well-mixed paste forms. Add parsley, mint, lemon juice and zest, coriander, and red pepper flakes. Pulse until everything is combined.
Transfer to a small bowl and mix in the flour and baking powder.
Form into small ping-pong shaped balls and place about 1 inch apart on a greased baking sheet (you should be able to make around 15 balls).
Bake for 20-23 minutes, flipping over at the halfway mark. Remove from oven and enjoy warm or cool!
