Soak chickpeas in a medium bowl in enough cold water to cover by at least 2 inches. Cover and allow to soak at room temperature overnight.
Drain chickpeas and transfer to food processor. Add the scallions, parsley, cilantro, chickpea flour, garlic, salt, pepper, cumin, and cinnamon. Process until the chickpeas are coarsely minced and the ingredients are evenly mixed. Do not over process so that the mixture forms a paste . Form mixture into 1.5-2" patties. Cover and refrigerate until ready to cook.
Pour enough oil into a large skillet to cover the bottom. Heat over medium high. When oil is hot, carefully add the falafel patties to the oil. Cook until golden brown on the bottom. Flip and continue cooking until both sides are golden brown. Reduce heat to medium if the patties are browning too quickly. Carefully transfer to a paper towel lined plate. Keep warm in a 200°F oven if needed or serve immediately. Serve in a pita sandwich or on their own with tahini sauce or hummus.
