My Grandmother's Peach Cobbler with the Biscuit Topping That Stays Crispy Every Time
This peach cobbler features a buttermilk biscuit topping that stays crisp thanks to a simple syrup-reduction trick. Made in a hot cast iron skillet, it's the perfect summer dessert.
Equipment
- 10-inch cast iron skillet
- Large Mixing Bowl
- Medium Mixing Bowl
- Small saucepan
- Pastry cutter or two forks
- Measuring Cups and Spoons
Ingredients
- 3 lbs ripe peaches (about 6 medium), sliced into wedges
- 2/3 cup granulated sugar
- 2 tbsp fresh lemon juice
- 1/4 tsp salt
- 1/2 cup unsalted butter (for the skillet)
For the biscuit topping
- 1 1/2 cups all-purpose flour (spooned and leveled)
- 1/4 cup granulated sugar
- 1 1/2 tsp baking powder
- 1/2 tsp baking soda
- 1/4 tsp salt
- 6 tbsp cold unsalted butter, cubed
- 3/4 cup cold buttermilk
Instructions
- Preheat your oven to 400°F with a rack in the center.
- Maceration: Slice the peaches into even wedges (about 6 per peach). Toss them in a large bowl with 2/3 cup sugar, lemon juice, and salt. Let sit for 30 minutes undisturbed until a pool of syrupy juice gathers at the bottom.
- Reduce the syrup: Pour the juice from the peach bowl into a small saucepan. Bring to a simmer over medium heat and let bubble gently until thickened, about 8–10 minutes. It should coat the back of a spoon like warm honey. Pour back over the peaches and stir gently.
- Hot skillet: Place 1/2 cup butter in your cold skillet. Put it in the oven for 5 minutes until the butter is fully melted and sizzling.
- Make the biscuit topping: In a medium bowl, whisk the flour, 1/4 cup sugar, baking powder, baking soda, and salt. Drop in the cold cubed butter. Cut it into the flour using a pastry cutter or your fingers until it looks like coarse meal with some pea-sized butter chunks. Pour in the cold buttermilk and stir with a fork until just combined. The dough will look shaggy.
- Assemble and bake: Pull the hot skillet from the oven. Drop spoonfuls of biscuit dough evenly over the melted butter. Spoon the peaches and reduced syrup over and around the dough. Bake for 35–40 minutes, until the topping is deep golden brown and the fruit is bubbling thickly at the edges. Let rest at least 15 minutes before serving.
Notes
Chef's tips: For the crispiest topping, don't skip the hot skillet step – the batter hitting the sizzling butter creates a caramelized bottom edge. Keep the biscuit butter very cold; pop cubed butter in the freezer for 10 minutes before starting. Always let the cobbler rest the full 15 minutes – if you cut into it right away, the syrup runs and the biscuits don't set. Variations: For gluten-free, use a 1:1 GF flour blend with xanthan gum. For dairy-free, use plant-based butter and oat milk + lemon juice for buttermilk. Add bourbon, cinnamon, or blackberries as desired.
