Preheat your oven to 350°F (175°C). Grease a 9x9 inch baking dish or similar size with butter or cooking spray.

Drain the fruit cocktail, reserving the syrup. Spread the drained fruit evenly in the prepared baking dish.

In a mixing bowl, whisk together the flour, sugar, baking powder, and salt until well combined.

Pour the melted butter over the dry ingredients and mix until the mixture resembles coarse crumbs.

Sprinkle the crumb mixture evenly over the fruit cocktail in the baking dish.

Carefully pour the reserved fruit syrup evenly over the entire cobbler.

Bake in the preheated oven for 35-40 minutes or until the top is golden brown and the filling is bubbly.

Remove from the oven and let it cool slightly before serving. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream if desired.
