Blackberries and apples come together in this delicious slab-style pie that will wow the crowd every time. An irresistible crumb topping makes it extra-special.
No need to clean the food processor between making the pie crust dough and the crumb topping!
If you want, you can make the pie crust dough a day ahead, leaving it chilled and wrapped in plastic until ready to roll out. Just remove it from refrigerator for about 30 minutes to make it easier to roll out smoothly.
