Preheat oven to 325°F.
Lightly spray a 9-inch-square baking dish with cooking spray.
Combine pears and cranberries in a large bowl, add the orange zest, honey, cornstarch and cinnamon and pour it into the baking dish.
In another bowl, combine the crumble topping ingredients and sprinkle evenly over the fruit.
Bake uncovered for about 60 minutes or until browned and bubbly. Serve warm.
