Preheat the oven to 400 degrees.
Drain and rinse chickpeas under cold water.
Pour the chickpeas onto an absorbent towel and pat dry. Remove the skins that have come off but don't worry about removing the rest of the skins.
Bake for 30 minutes.
Transfer the chickpeas into a mixing bowl and top with oil, maple syrup, cinnamon and salt, and coat well.
Bake for another 5-10 minutes or until crispy throughout. The exact bake time will depend on your oven and the brand of chickpeas. Keep checking them at the end every few minutes. You want the chickpeas to be crispy and browned, but not burnt and hard.
Remove from oven and sprinkle with sugar and a dash more salt (if desired). Let cool completely. Enjoy!
