Pour melted butter into the bottom of a 9x13-inch glass baking dish.
Mix milk, flour, sugar, baking powder, and salt together in a small bowl; pour over the butter in the baking dish. Arrange strawberry halves in a layer into the baking dish. Dot the strawberries with the cream cheese pieces.
Bake in preheated oven until top is golden brown and edges are bubbling, 30 to 45 minutes.
