Step 1

Preheat oven to 375-degrees F. Butter a 9- x 9-inch baking dish; set aside.

Step 2

In a medium mixing bowl, whisk together flour, salt, and brown sugar. Pour ½ cup melted butter over flour mixture. By hand, stir until crumbly. Set aside while preparing fruit filling.

Step 3

In a large mixing bowl, gently stir together the peaches, plums and blueberries. Pour vanilla extract and melted butter over fruit and fold together.

Step 4

In medium bowl, stir together the flour, sugar, cinnamon, nutmeg and salt. Pour over fruit and stir gently until sugar/flour mixture is well incorporated.

Step 5

Turn out fruit mixture into prepared baking dish; distribute evenly. Crumble topping over fruit. Bake for 45 minutes until hot and bubbly and topping is deep golden brown. If topping is browning too quickly, lay a piece of aluminum foil over the topping without sealing the edges.

Step 6

Serve warm with vanilla ice cream, if desired. Store refrigerated for up to 3 days.
