Ingredients:
- 24 oz (680g) frozen peach slices, unglazed
- 1/4 cup (50g) granulated sugar
- 2 tbsp (16g) cornstarch
- 1/2 tsp (1g) ground cinnamon
- 1 tbsp (15ml) lemon juice
- 1 cup (90g) old-fashioned rolled oats
- 1 cup (125g) all-purpose flour
- 1 cup (200g) packed light brown sugar
- 1/2 cup (113g) unsalted butter, cold and cubed
- 1/2 tsp (3g) salt
Instructions:
- Toss the frozen peach slices in a medium bowl with granulated sugar, cornstarch, cinnamon, and lemon juice until evenly coated. Note: Don't thaw the peaches first; the cornstarch works best on the cold fruit.
- Pour the peach mixture into a 9x9 inch baking dish and spread into an even layer.
- In a large bowl, whisk together the rolled oats, all purpose flour, brown sugar, and salt.
- Add the cold, cubed butter to the dry ingredients.
- Use a pastry cutter or fork to work the butter in until the mixture resembles coarse crumbs with pea sized lumps. Note: Avoid overmixing or the topping will become a paste.
- Scatter the crumble topping evenly over the peaches, pressing down lightly.
- Bake in a preheated 375°F (190°C) oven for 40–45 minutes.
- Remove from oven until the fruit juices are bubbling thick and the topping is deep golden brown.
