Rinse and drain the chickpeas. Pat them dry with a paper towel.
Spread the chickpeas on baking sheet line with parchment paper.
Bake for 45- 50 minutes. Give the pan a little shake every 15 minutes to move them around.
You want to bake them until they are crunchy all the way through. Test one. If it's still soft in the middle, cook a little longer. Retest until completely crunchy.
In a small bowl, combine the olive oil, maple syrup , brown sugar, cinnamon.
Put the chickpeas into the the maple syrup mixture and toss until they are coated.
Put them back onto the lined baking sheet and caramelize for about 10-15 mins.
