Blueberry Peach Cobbler

Key Ingredients and What to Look For

Peaches: Choose ripe but firm freestone peaches—they’ll hold their shape during baking and release just enough juice. If the peaches are very soft, reduce the sugar slightly. For the best flavor, use in-season local peaches. Blueberries: Fresh or frozen both work; if using frozen, no need to thaw. Look for plump, deep-blue berries with a silvery bloom—that’s a sign of freshness. Cornstarch: This thickens the fruit juices into a luscious syrup. You can substitute arrowroot powder in equal measure, but avoid all-purpose flour, which can make the filling cloudy.

Tools You’ll Need

9×13-inch baking dish (glass or ceramic works well for even heat distribution). Large rimmed baking sheet lined with foil—essential for catching any drips. Box grater for grating cold butter (a food processor with a grating disc also works). Small cookie scoop (optional but helpful for dropping the batter evenly). Mixing bowls, whisk, and a rubber spatula.

Tips for a Perfectly Flaky Cobbler

The secret to that tender, golden crust lies in keeping the butter as cold as possible. Grate it straight from the fridge—the small shreds distribute evenly and create steam pockets as they melt, giving you a light, biscuit-like topping. When you stir in the boiling water, work quickly and stop as soon as the dough comes together; those visible lumps of butter are exactly what you want. And don’t skip the foil-lined baking sheet on the rack below—I’ve learned the hard way that this cobbler loves to bubble over, and that pan saves you a messy cleanup. For the best texture, let the filling bake for the full 10 minutes before adding the batter; that head start thickens the juices so the topping doesn’t sink into a soggy mess.

Mix It Up: Variations to Try

Swap the peaches for nectarines or plums—they have a similar texture and sweetness, so no other adjustments needed. For a boozy twist, stir 2 tablespoons of bourbon or vanilla extract into the fruit mixture before baking. To make this gluten-free, substitute a 1-to-1 gluten-free flour blend for the all-purpose flour; the topping will be slightly more tender but still delicious. If you prefer a crunchy streusel topping, replace the batter with a mixture of 1 cup flour, ½ cup brown sugar, ½ cup cold butter (cut in), and ½ cup oats—sprinkle over the fruit and bake as directed.

Ways to Serve This Summer Fruit Cobbler

A scoop of vanilla ice cream is the classic partner—its cool creaminess balances the warm, spiced fruit and flaky crust. For a tangier contrast, try a dollop of crème fraîche or a drizzle of heavy cream. If you want a little crunch, scatter toasted sliced almonds or a pinch of flaky sea salt over the top just before serving. Pair it with a tall glass of sweet tea or a crisp rosé for a true summer dessert spread.

Storing Leftover Cobbler

Cover the cooled cobbler tightly with foil or plastic wrap and refrigerate for up to 4 days. The topping will soften over time, but the fruit stays juicy and flavorful. For the best texture, reheat individual portions before serving.

How to Freeze This Cobbler

Freeze the fully baked and cooled cobbler for up to 3 months. Wrap the entire dish in a layer of plastic wrap, then a layer of foil, or transfer portions to airtight freezer containers. To thaw, move it to the refrigerator overnight. Reheat in a 350°F oven until warmed through and the topping crisps up again—about 15 to 20 minutes. You can also freeze the unbaked filling and batter separately; assemble and bake straight from the freezer, adding 10 to 15 minutes to the baking time.

The Best Way to Reheat Cobbler

For a crust that stays crisp, reheat in a 350°F oven. Place individual servings on a baking sheet and warm for 10 to 12 minutes, or until the filling is bubbly and the topping is golden. The microwave works in a pinch (about 45 seconds per serving), but the crust will turn soft. If you have an air fryer, set it to 350°F and reheat for 5 to 7 minutes—it restores some of that flaky texture beautifully.

• 1 tsp ground cinnamon
• 0.5 tsp ground cardamom

crust topping

• 2 cup all-purpose flour
• 1 cup light brown sugar
• 2 tsp baking powder
• 1 tsp kosher salt
• 12 tbsp butter cold, grated
• 0.5 cup boiling water

cinnamon sugar topping

• 0.333 cup white sugar
• 2 tsp cinnamon

Equipment

• 9×13 baking dish
• large baking sheet
• foil
• mixing bowls
• whisk
• cheese grater
• cookie scoop
• toothpick

Instructions

 

1. Preheat oven to 425°F. Place a large baking sheet covered in foil on the lowest rack in the oven. This cobbler overflows a bit almost every time I make it. The baking pan will catch the drips and prevent a mess in the oven.
2. In a large bowl, combine the peaches, blueberries, lemon juice, sugar, cornstarch, and cinnamon. Stir to coat and then pour into a 9×13 baking dish. Bake for 10 minutes.
3. While the filling is in the oven, whisk together the flour, brown sugar, baking powder, and salt. Toss the grated butter into the flour mixture. Stir in the boiling water, just until combined, leaving plenty of little lumps of butter.
4. Remove the filling from the oven and spoon the lumpy batter on top of it. (I like to use my smallest cookie scoop to do this.) Mix together the cinnamon and sugar and sprinkle it onto the cobbler topping.
5. Bake until the crust is golden and a toothpick inserted into the crust comes out clean, about 20-24 minutes. Let cool for 10 minutes. Serve warm with a scoop of vanilla ice cream, if desired.
