01 - Preheat oven to 350°F (180°C) and line a baking sheet with parchment paper.
02 - In a mixing bowl, whisk together the chickpea flour, sea salt, garlic powder, smoked paprika, and ground cumin until evenly distributed.
03 - Add water and 1 tablespoon olive oil to the dry ingredients. Whisk vigorously until a smooth, lump-free batter forms.
04 - Pour the batter onto the prepared baking sheet and spread evenly to approximately 1/8 inch (2-3 mm) thickness using a spatula.
05 - Bake for 10 minutes until the surface is set. Remove from the oven and brush evenly with the remaining 1 tablespoon 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 chips to cool completely on the baking sheet, then break along the scored lines. Sprinkle with additional sea salt to taste if desired.
