Skillet Blueberry Cobbler with Buttermilk Biscuits

This skillet blueberry cobbler brings together juicy, jammy berries and flaky, golden buttermilk biscuits in one rustic cast iron pan.

A crunchy turbinado sugar topping adds a satisfying crackle, while a scoop of melting vanilla ice cream turns it into pure Southern comfort. It's a straightforward dessert that feels special enough for company but easy enough for a weeknight.

The magic of this cobbler lies in its simplicity: fresh blueberries tossed with sugar, cornstarch, lemon juice, and cinnamon, then topped with a light, tender biscuit dough.

Baked in a cast iron skillet, the berries bubble into a thick, glossy sauce while the biscuits turn golden and flaky. The combination of warm, tart fruit and buttery, slightly sweet biscuits is irresistible.

Ingredients

Why this recipe works

The biscuit dough relies on cold butter and cold buttermilk to create steam pockets during baking, which results in flaky, tender layers.

Cutting the butter into pea-sized pieces ensures those pockets form, giving the biscuits their signature lift and texture. The cold buttermilk not only adds tang but also keeps the dough from becoming tough.

Baking in a cast iron skillet distributes heat evenly, allowing the berry filling to thicken and bubble while the biscuits bake to golden perfection.

The skillet's high sides contain the bubbling juices, and the pan's heat helps create a crispy bottom crust on the biscuits. This one-pan approach also makes serving and cleanup effortless.

Notes and substitutions

Use fresh blueberries for the best texture and flavor. If using frozen, do not thaw them first, and add a couple of minutes to the baking time. The lemon juice brightens the berries and helps balance the sweetness, while the cinnamon adds warmth without overpowering the fruit.

For the biscuits, use a high-quality all-purpose flour and unsalted butter. The dough should be just combined—overmixing will develop gluten and make the biscuits tough. If the dough seems too dry, add a splash more buttermilk; if too wet, a little more flour. The rustic mounds are intentional, so no need to roll or cut them.
