Awesome Sweet Potato Casserole

1 (8 ounce) can crushed pineapple, drained

½ (14 ounce) bag flaked coconut, or more to taste

3 cups cooked mashed sweet potatoes

1 cup white sugar

2 eggs

1 teaspoon vanilla extract

⅓ cup milk

½ cup butter, melted

⅓ cup all-purpose flour

1 cup firmly packed brown sugar

⅓ cup butter, melted

1 cup finely chopped pecans

Preheat an oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.

Beat the pineapple, coconut, sweet potatoes, white sugar, eggs, vanilla extract, milk, and 1/2 cup melted butter together in a large mixing bowl until smooth. Pour mixture into the prepared pan; set aside. Mix the flour, brown sugar, 1/3 cup butter, and pecans in a bowl. Sprinkle pecan mixture over the batter.

Bake in the preheated oven until the casserole is bubbly and the topping is browned, about 30 minutes.
