📝 About This Recipe

This quintessential American dessert captures the essence of summer with a bubbling, jammy layer of fresh blueberries nestled beneath a golden, pillowy buttermilk biscuit crust. Unlike a pie, this cobbler celebrates a rustic charm, where the fruit juices mingle with a hint of lemon and cinnamon to create a luscious sauce. It is the ultimate comfort food, striking a perfect balance between the tartness of the berries and the buttery, sugary crunch of the topping.

🥗 Ingredients

The Blueberry Filling

  • 6 cups Fresh Blueberries (rinsed and patted dry)
  • 1/2 cup Granulated Sugar (adjust based on sweetness of berries)
  • 1 tablespoon Cornstarch (for thickening)
  • 1 tablespoon Lemon Juice (freshly squeezed)
  • 1 teaspoon Lemon Zest (finely grated)
  • 1/4 teaspoon Ground Cinnamon

The Biscuit Topping

  • 1 1/2 cups All-Purpose Flour (spooned and leveled)
  • 1/4 cup Granulated Sugar (plus extra for sprinkling)
  • 1 1/2 teaspoons Baking Powder
  • 1/2 teaspoon Fine Sea Salt
  • 6 tablespoons Unsalted Butter (cold, cut into 1/2-inch cubes)
  • 1/2 cup Buttermilk (cold; full-fat preferred)
  • 1 teaspoon Vanilla Extract (pure extract)
  • 1/4 cup Boiling Water (to be added last to the batter)

The Finishing Touch

  • 1 tablespoon Turbinado Sugar (for a crunchy texture)
  • 1 tablespoon Unsalted Butter (melted, for brushing)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 375°F (190°C). Lightly grease a 9x9-inch square baking dish or a 2-quart round casserole dish with butter.

  2. 2

    In a large mixing bowl, combine the blueberries, 1/2 cup granulated sugar, cornstarch, lemon juice, lemon zest, and cinnamon. Toss gently until the berries are evenly coated.

  3. 3

    Transfer the blueberry mixture into the prepared baking dish, spreading it out in an even layer. Set aside while you prepare the topping.

  4. 4

    In a separate medium bowl, whisk together the flour, 1/4 cup sugar, baking powder, and salt until well combined.

  5. 5

    Add the cold, cubed butter to the flour mixture. Using a pastry cutter or your fingertips, work the butter into the flour until it resembles coarse crumbs with some pea-sized pieces remaining.

  6. 6

    In a small measuring cup, stir the vanilla extract into the cold buttermilk.

  7. 7

    Pour the buttermilk mixture into the flour and butter mixture. Stir with a fork just until the dough starts to come together; do not overmix.

  8. 8

    Carefully pour the 1/4 cup of boiling water over the dough and stir gently. This 'hot water' method creates a unique, tender, cake-like consistency in the biscuit topping.

  9. 9

    Drop large spoonfuls of the dough over the blueberries. It doesn't need to cover the fruit completely; leaving small gaps allows steam to escape and the fruit to bubble through.

  10. 10

    Brush the tops of the dough mounds with the melted tablespoon of butter and sprinkle generously with turbinado sugar.

  11. 11

    Place the dish on a baking sheet (to catch any drips) and bake for 40-45 minutes. The topping should be deep golden brown and the fruit juices should be thick and bubbling.

  12. 12

    Remove from the oven and let the cobbler cool on a wire rack for at least 15-20 minutes. This resting period is crucial for the juices to set properly.

💡 Chef's Tips

Always use cold butter and cold buttermilk to ensure a flaky, tender biscuit topping. If using frozen blueberries, do not thaw them first; simply increase the cornstarch by half a tablespoon to manage the extra moisture. Avoid over-mixing the dough once the liquid is added, as this develops gluten and can make the topping tough. Check the cobbler at the 30-minute mark; if the top is browning too quickly, tent it loosely with aluminum foil. For a flavor twist, add 1/2 teaspoon of ground ginger to the berry mix for a subtle spicy warmth.

🍽️ Serving Suggestions

Serve warm with a generous scoop of high-quality vanilla bean ice cream. Drizzle with a bit of cold heavy cream for a classic, less sweet alternative to ice cream. Pair with a glass of chilled Moscato or a light dessert wine to complement the fruit acidity. A dollop of lemon-scented whipped cream adds a bright, zesty contrast to the sweet berries. Enjoy any leftovers cold for breakfast with a spoonful of Greek yogurt.
