Apple Blackberry Crumble
sandravalvassori.com
Embrace the flavors of fall with this easy and delightful Apple Blackberry Crumble. Juicy, sweet apples and tart blackberries create a luscious filling that’s topped with a golden, buttery crumble. Not too sweet and perfectly spiced, it's a comforting dessert that is virtuous enough to eat for breakfast over yogurt, and ridiculously indulgent warm from the oven with a scoop of melting ice cream.
Servings: 8
Ingredients
For The Filling
- soft butter for greasing baking dish
- 6 large apples, about 2 1/2 to 3 pounds (I use a mix of sweet-tart apples-see notes below)
- 1 tablespoon lemon juice, or more if needed
- 2-3 tablespoons brown sugar or granulated sugar (see notes)
- 1 tablespoon cornstarch
- 1/4 teaspoon cinnamon, or more to taste
- 1 teaspoon vanilla extract, optional
- 1/4 teaspoon kosher salt
- 2 cups blackberries, gently rinsed and dried (can use frozen-do not thaw)
For The Crumble Topping
- 1 cup (130 g) all-purpose flour
- 1 cup (80 g) old-fashioned rolled oats
- 1/2 cup (106 g) light brown sugar, tightly packed
- 2/3 cups ( 75 g) chopped walnuts
- 1 teaspoon cinnamon
- 1/2 teaspoon baking powder, optional
- 1/2 teaspoon kosher salt
- 1 stick (115 g) unsalted butter, melted
Instructions
- Preheat oven to 350ºF. Using soft butter, lightly grease the bottom and sides of a 9x13 baking dish.
- Using a vegetable peeler, peel all the apples. Stand your peeled apple upright, place your knife close to the core and cut downward to remove large chunks of apples. You should get 4 chunks from each apple. Then, cut each chunk into slices that are a little thicker than 1/4-inch – so about three-eighths of an inch.
- Place the apple slices in a large bowl and toss them with the lemon juice, sugar, cornstarch, cinnamon, vanilla and salt, until well combined. Add the blackberries and toss gently to combine. Pour mixture into prepared baking dish, spreading the apples and berries into an even layer.
- In a medium bowl, combine the flour, oats, brown sugar, walnuts, cinnamon, baking powder, and salt. Add the melted butter and use a fork or rubber spatula to stir the mixture until the crumbs look evenly moistened.
- Sprinkle topping evenly over the filling then bake for 50-60 minutes, or until juices are bubbling at center of crumble and topping is golden brown. TIP: Place baking dish on a sheet pan to catch any drippings.
- Let rest, covered with foil, for 15 minutes to allow the juices to set. Serve with heavy cream, whipped cream, or ice cream, if desired.
Notes
Sugar - Apples will vary greatly in sweetness so you will want to adjust the amount of sugar accordingly.If your apples are sweet, add only 1 tablespoon of sugar to the filling. For apples that are sweet-tart, add two tablespoons. If you are using all tart apples, add 3 tablespoons of sugar.
A note on salt - I only use Diamond Crystal Kosher salt for all my cooking and baking. Other brands, or table salt, might be saltier so err on the side of caution and use a little less.
