01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Pat the chickpeas thoroughly dry with a clean towel. Remove any loose skins for maximum crispiness.
03 - In a large bowl, whisk together the maple syrup, olive oil, chili powder, smoked paprika, cayenne pepper (if using), garlic powder, cumin, and salt until well combined.
04 - Add the chickpeas to the bowl and toss to coat evenly. Sprinkle the corn starch or arrowroot powder over the mixture and stir until the chickpeas are uniformly coated and slightly sticky.
05 - Spread the coated chickpeas on the prepared baking sheet in small clusters (about 1 to 2 teaspoons each), leaving space between each cluster for even roasting.
06 - Bake for 30 to 35 minutes, shaking the pan or turning the clusters halfway through, until golden, crisp, and caramelized. Watch closely during the last 5 minutes to prevent burning.
07 - Let the clusters cool completely on the tray. They will crisp up further as they cool. Store in an airtight container for up to 4 days.
