In a bowl, mix together all of the filling ingredients and set aside.
2 pounds apples, 1 cup blackberries, 1 tablespoon orange juice, zest of one orange, 1 tablespoon cornstarch, 2 tablespoons granulated sugar, 1/2 teaspoon ground cinnamon, 1/4 teaspoon vanilla, 1/2 teaspoon kosher salt
Stir together all topping ingredients except for the butter
1/3 cup all purpose flour, 1/3 cup brown sugar, 1/3 cup white granulated sugar, 2/3 cups rolled oats
Cut cold butter into small pieces and mix in to the oat topping. You can use a fork or a pastry cutter, but I use my hands. You want to get it thoroughly mixed in, ideally to form pea-sized pieces.
6 tablespoons butter
Place filling in baking dish and crumble the topping over it until the filling is covered. Bake for 30-40 minutes until topping is golden brown and apples are fork-soft

Notes
**Notes:1. If using frozen blackberries, let them thaw first. Using them frozen will release too much water and make your filling soupy.2. Use at least some Granny Smith apples for firmness. You can mix and match with others (best alternatives are described in the post above)3. Make sure the butter is cold when incorporating it into the topping mixture.**Want more like this?
