In a large bowl, using a large spoon or rubber spatula, combine the melted butter, apples, cranberries, sugar, flour, and cinnamon. Stir until well mixed and fruit is covered with mixture.
Pour the entire fruit mixture into a pie plate, spreading evenly.
In a medium bowl, combine flour, brown sugar, salt, melted butter, and sugar, stirring with a spatula or fork to fluff the crumble mixture. Sprinkle over the filling, covering as much as possible.
Bake at 350 degrees for 30-35 minutes, until the top crumble is a light golden brown.
Notes
No need to peel apples first!
