Step 1

Preheat oven to 350 degrees F and grease a 9-inch round baking dish with butter or nonstick spray.

Step 2

In a medium bowl, stir together 1 cup of the sugar, the flour, baking powder, and salt. Add the milk and combine. Add the melted butter and whisk until smooth.

Step 3

Pour the batter into the greased baking dish. Scatter the top with all of the blackberries. Sprinkle 1/4 cup of sugar over the top.

Step 4

Bake until edges are golden and crispy, 50-60 minutes. When 10 minutes remain (topping is just turning golden), sprinkle with remaining 2 tablespoons sugar.

Step 5

Serve warm with whipped cream or ice cream, if desired.
