Spread the blueberry pie filling evenly across the bottom of the dish. Stir in the lemon zest (and fresh blueberries if using) for extra brightness.
Sprinkle the dry lemon cake mix evenly over the fruit layer—don’t stir.
Drizzle the melted butter evenly over the top, making sure most of the dry mix is moistened.
Bake for 40–45 minutes, until the top is golden and crisp and the filling is bubbling around the edges.
Let it cool slightly before serving.
