Combining sweet tart apples and blueberries with a buttery, crunchy crumble topping, this dessert is begging to be eaten on a warm summer night with a big scoop of ice cream!
Prepare the fruit filling. Chop the apples into bite size pieces. In a large bowl, toss together the apples, blueberries, brown sugar, cornstarch, cinnamon, cardamom, lemon juice, salt, and vanilla.
