This old-fashioned dessert of warm baked apples and tart cranberries with a crunchy oat streusel topping comes from Rustic Fruit Desserts by Cory Schreiber and Julie Richardson, a small and unassuming little cookbook full of yummy treasures. If you’re at all intimidated by baking, or just think of it as one of those things that other people do, this recipe is for you. There’s no fussy pie dough — just fruit tossed with sugar and cinnamon and a simple crumb topping of oats, flour, brown sugar and butter. Serve the crumble warm out of the oven topped with vanilla ice cream or whipped cream. Leftovers are delicious plain, especially for breakfast.
Apple Cranberry Oat Crumble
For the Dish
- 1 tablespoon unsalted butter, at room temperature
For the Topping
- 2 cups rolled oats
- 1-1/2 cups all-purpose flour, spooned into measuring cup and leveled-off
- 1-1/3 cups packed light brown sugar
- 1/2 teaspoon salt
- 1-1/2 sticks (12 tablespoons) unsalted butter, melted
For the Fruit Filling
- 8 large baking apples, peeled, cored and sliced 1/4-inch thick
- 2 cups (8 ounces) fresh or frozen cranberries
- 1-1/3 cups granulated sugar
- 2 tablespoons cornstarch
- 2 teaspoons ground cinnamon
- Preheat the oven to 375°F. Butter a 3-quart, or 9 x 13-inch, baking dish.
- To make the topping, mix the oats, flour, brown sugar and salt together in a bowl. Stir in the melted butter, then press the topping together with your hands to form small clumps. Put the topping in the freezer while you assemble the filling.
- To make the fruit filling, toss the apples, cranberries, sugar, cornstarch and cinnamon together in a large bowl. Transfer the filling to the prepared pan and spread it out, pressing the fruit down into the corners.
- Press the oat crumble evenly over the fruit, then bake for 60-70 minutes, or until the crumble is lightly golden and the filling is bubbling up in the corners. Cool for about 20 minutes to temper the heat before serving, then top with vanilla ice cream or sweetened whipped cream.
- Note: This crumble is best served the day it is made, but any leftovers can be wrapped in plastic wrap and kept at room temperature for 2 to 3 days. Reheat in a 300 degree oven for 10-15 minutes, until warm.
- Freezer-Friendly Instructions: After baking, the crumble can be frozen tightly covered for up to 3 months. Before serving, reheat it, uncovered, in a 300°F oven until heated through and crisp on top.
