In a large mixing bowl, whisk together the chickpea flour, water, olive oil, salt, and optional sugar until the batter is completely smooth and lump-free, about 1-2 minutes.

Cover the batter with a kitchen towel and let it rest at room temperature for at least 30 minutes.

Preheat your waffle iron to medium-high heat, which usually takes about 5 minutes. Brush with a thin layer of olive oil to prevent sticking.

Pour the batter into the waffle iron according to manufacturer’s guidelines, usually about 1/2 to 3/4 cup per waffle. Cook for approximately 4-6 minutes or until golden brown.

Remove the chickpea waffles from the iron using a fork or spatula. Serve warm with your favorite toppings.
