Place the tray of coconut flakes in the oven for 5 minutes, then remove the tray and stir the coconut. Repeat this 2-3 more times until the coconut is toasted to a light golden brown. Be careful, the coconut will brown quickly once it begins to toast.
Remove the tray from the oven and allow it to cool on a cooling rack.

In a medium bowl, add the toasted coconut and the contents of caramel spice bowl and stir till mixed evenly.
