A comforting and addictive blueberry cobbler featuring a fluffy buttermilk biscuit topping that is golden and pillowy, perfectly balancing sweet-tart blueberries with a tender biscuit crust.

Ingredients

Scale
  • 3 cups fresh blueberries (or frozen, thawed and drained)
  • ½ cup granulated sugar (adjust based on berry sweetness)
  • 2 tablespoons cornstarch (for thickening, tapioca starch works too)
  • 1 teaspoon freshly grated lemon zest
  • 1 tablespoon lemon juice
  • ½ teaspoon ground cinnamon (optional)
  • 1 cup all-purpose flour
  • 1 ½ teaspoons baking powder
  • ¼ teaspoon baking soda
  • ⅓ cup cold unsalted butter, cubed
  • ⅓ cup granulated sugar
  • ½ cup buttermilk (room temperature; or milk + vinegar/lemon juice as substitute)
  • 1 teaspoon vanilla extract (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish with butter or non-stick spray.
  2. In a medium bowl, combine blueberries, sugar, cornstarch, lemon zest, lemon juice, and cinnamon if using. Gently toss to mix and set aside to macerate.
  3. In a large bowl, whisk together flour, baking powder, baking soda, and sugar.
  4. Add cold, cubed butter to the flour mixture. Use a pastry cutter or two forks to cut the butter into the flour until the mixture resembles coarse crumbs with pea-sized butter pieces.
  5. Stir in buttermilk and vanilla extract just until combined. The dough will be sticky and slightly shaggy; do not overmix.
  6. Pour the blueberry mixture into the prepared baking dish, spreading evenly.
  7. Drop spoonfuls of biscuit dough over the berries, covering as much surface as possible but leaving some gaps for juices to bubble through.
  8. Bake for 35-40 minutes or until the biscuit topping is golden brown and springy to the touch and the berry filling is bubbling around the edges.
  9. Let the cobbler cool for 10-15 minutes before serving to allow the juices to thicken.

Notes

Use cold butter to ensure flaky biscuit topping. Do not overmix the dough to avoid dense biscuits. If topping browns too quickly, tent with foil halfway through baking. For extra browning, brush biscuit tops with melted butter and sugar before baking. You can prepare filling and dough ahead and refrigerate; bring dough to room temperature before baking. Use parchment paper for easier cleanup if berry juices run wild.
