Whipped cream or vanilla ice creamfor serving (optional)
Instructions
Preheat your oven to 350°F. Place the butter pieces in a 9x13-inch baking dish and let them melt in the oven for a few minutes.
In a bowl, combine the blueberries with 1/2 cup sugar, lemon juice, and the lemon zest.
In another bowl, whisk together the flour, 1 cup sugar, baking powder, and salt. Stir in the vanilla and buttermilk until just combined; do not overmix.
Remove the dish from the oven. Pour the blueberry mixture evenly over the melted butter, then drizzle the batter over the top. Sprinkle a pinch of ground cinnamon over everything.
Bake in the preheated oven for 35 minutes, or until the top is lightly golden and a toothpick inserted in the center comes out clean.
Let the cobbler cool for a few minutes before serving. For an extra treat, top with a dollop of whipped cream or a scoop of ice cream when serving.
