- With the rack in the middle position, preheat the oven to 350°F (180°C).
- In a large bowl, combine the sugar, cornstarch and cinnamon. Add the fruit and toss well to coat. Transfer to an 11 x 8-inch (28 x 20 cm) glass baking dish.
- In another bowl, combine the remaining ingredients until just moistened. Spread over the fruit mixture in the baking dish.
- Bake for 45 minutes or until the fruit is bubbling and the topping is golden. Let cool for 1 hour before serving.
Frozen fruit will also work well in this recipe. In this case, add an additional 1 tbsp cornstarch.
