01 - Preheat oven to 350°F (180°C). Line a baking sheet with parchment paper and set aside.
02 - In a mixing bowl, whisk together the chickpea flour, sea salt, garlic powder, smoked paprika, and ground cumin until evenly distributed.
03 - Pour in the water and 1 tablespoon of olive oil. Whisk thoroughly until a smooth, lump-free batter forms.
04 - Pour the batter onto the prepared baking sheet. Using a spatula, spread it evenly to approximately 1/8 inch (2–3 mm) thickness.
05 - Bake for 10 minutes until the surface is just set. Remove from the oven and brush evenly with the remaining 1 tablespoon of olive oil.
06 - Using a sharp knife or pizza cutter, score the partially baked sheet into chip-sized squares or triangles.
07 - Return to the oven and bake for an additional 12–15 minutes until the chips are golden brown and crisp. For even crispier results, flip the chips halfway through this second bake.
08 - Allow the chips to cool completely on the baking sheet. Break along the scored lines and sprinkle with additional sea salt to taste.
