Vanilla ice cream or whipped cream, for serving (optional)
Instructions
Preheat oven to 350 degrees F and grease a 9-inch round baking dish with butter or nonstick spray.
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.
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.
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.
Serve warm with whipped cream or ice cream, if desired.
