Step 1

Preheat the oven to 350°F.

Step 2

In a large bowl, stir together blueberries, sugar, and lemon zest until combined. Set aside.

Step 3

Place the butter in a 13x9-inch baking dish. Place the dish in the preheated oven until the butter is melted, about 10 minutes.

Step 4

Meanwhile, in a medium mixing bowl, whisk together the flour, sugar, baking powder, and salt. Whisk in the milk until just combined.

Step 5

Carefully remove the baking dish from the oven, and pour the batter into the pan (do not stir). Sprinkle with the blueberries.

Step 6

Bake for 30 to 35 minutes or until the batter is golden brown and a wooden pick inserted in the center comes out mostly clean. Let the cobbler cool slightly before serving. Serve with a scoop of vanilla ice cream, if desired.
