In a large bowl, combine the garbanzo flour and cold water.

In a separate bowl, pour boiling water over the oat flakes.

Cover the oat flakes and let them stand for a few minutes to soften.

Add the softened oat flakes, chopped nuts, baking powder, vegetable oil, onion or garlic powder, cumin, and salt (if using) to the garbanzo flour mixture.

Stir all ingredients together thoroughly until well combined.

Heat an oiled griddle or frying pan over medium heat.

Form the mixture into patties.

Place the patties on the oiled griddle.

Cook until browned on one side.

Flip the patties and cook until browned on the other side.

Remove from heat and serve.

The patties can be refrigerated or frozen for future use. Reheat before serving.
