Mist the slices of bread, one at a time, and coat them in the cinnamon sugar mixture.
Lay coated bread on a baking sheet.
Bake at 220˚Ffor 45 minutes and then flip the cinnamon toasts over.
Return to the oven and bake for an additional 45-75 minutes, depending on the thickness of your bread, until the bread does not give when you press on it. You want it to be dry and crunchy.
