Preheat the oven to 350 °F (180 °C).
Before you start, make sure you selected chickpea flour made from garbanzo beans, not besan flour as the ratio of dry/liquid ingredients would be totally different! Besan flour needs less liquid.
In a mixing bowl, add chickpea flour and use a whisk to stir and break any lumps.
Whisk in bagel seasonings and spices if desired.
Add olive oil and 3 tablespoons of water. Stir with a rubber spatula, and if too dry, add the extra tablespoon of water. When it gets difficult to stir, lightly oil your hands and knead to form a soft dough.
Place the dough between two pieces of lightly oiled parchment paper and roll it with a rolling pin. I like to fold my parchment paper into a rectangle shape so the dough rolls into a perfect rectangle creating lovely square crackers.
Roll into a 0.1-inch thickness (2mm) peel off the top piece of parchment paper, then use a pizza wheel to cut out crackers.
Slide the piece of parchment paper with the chickpea tortilla chips onto a baking sheet and gently spread each cracker from eachother.
Bake on the center rack for 12-14 minutes at 350 °F (180 °C) until lightly golden brown and crispy. They firm up even more as they cool down, the longer you bake them, the harder and crispier they get.
Notes
Note 4: Bagel seasoning contains sesame seeds, onion powder, garlic powder, and salt. If you don’t have this at home swap for ½ teaspoon of salt + ¼ teaspoon of onion powder + ¼ teaspoon of garlic powder + ¼ teaspoon of black/white sesame seeds.
Storage: Store the crackers at room temperature in a sealed container for up to 2 weeks. You can double or triple the recipe and freeze the crackers for later in a sealed bag.
