Mix 1 cup sugar and 2 cups fruit together in a large mixing bowl and set aside.
Melt butter in a 9x9 ceramic or glass baking dish in the microwave until butter is completely melted and covering the bottom of the pan.
In a separate mixing bowl, mix ½ cup sugar, flour, baking powder, and salt. Add the milk and stir with a whisk until fully mixed. The batter should be on the runny side. Then pour the batter over the butter in the baking dish. Do not stir!
Place the sugar and fruit mixture on top of the batter. Do not stir this either.
Bake for approximately 1 hour at 350 degrees. The batter will rise to the top during baking and will be brown and crisp when done.
Serve with vanilla ice cream while the cobbler is hot.
