Peach Blueberry Cobbler with a Buttery Biscuit Top
This peach blueberry cobbler is the dessert I turn to when the fruit is so ripe it barely needs a spoonful of sugar.
The topping bakes up crisp on the edges and pillowy underneath, with jammy fruit bubbling up around the biscuits. It is the kind of thing you want on the counter after a weeknight dinner, warm and spooned into bowls.
Why This Cobbler Works
The fruit stays chunky instead of turning to mush because the thickener is just enough to coat it. You get distinct bites of peach and blueberry, not a sugary soup.
The biscuit topping is not very sweet, so it balances the natural sugar of the fruit and keeps the whole thing from feeling heavy. It comes together with nothing more than a bowl and a baking dish, making it an any-night dessert.
Ingredients
- 4 cups sliced ripe peaches (about 4 medium): look for fruit that gives slightly when pressed but is not mushy
- 1 cup fresh blueberries: wash and dry them well
- 1/3 cup granulated sugar: adjust depending on how sweet your fruit is
- 2 tbsp cornstarch: helps the juices thicken into a syrupy sauce
- 1 tbsp lemon juice: brightens the fruit and balances the sugar
- 1 tsp vanilla extract: rounds out the flavor
- 1 1/2 cups all-purpose flour: for the biscuit topping
- 1/4 cup granulated sugar: keeps the biscuits barely sweet
- 1 1/2 tsp baking powder: gives the topping lift
- 1/4 tsp salt: wakes up all the flavors
- 1/2 cup cold unsalted butter, cut into pieces: straight from the fridge, this makes flaky layers
- 2/3 cup cold heavy cream: plus a little extra for brushing the top
- Coarse or raw sugar: for a crunchy top (optional)
Variations / Substitutions
- Swap the fruit: nectarines, plums, or raspberries all work. Use the same volume and adjust the sugar if the fruit is very tart.
- Use brown sugar: replace the granulated sugar in the biscuit dough with light brown sugar for a deeper, molasses-like note.
- Gluten-free: use a 1:1 gluten-free flour blend that contains xanthan gum. The topping will be slightly more tender.
- Dairy-free: swap the butter for a solid vegan butter and the cream for full-fat oat or coconut milk. The topping will still brown and crisp.

How to Make Peach Blueberry Cobbler
Step 1: Toss the Fruit
Preheat the oven to 375°F (190°C). In a large bowl, combine the 4 cups sliced peaches, 1 cup blueberries, 1/3 cup granulated sugar, 2 tablespoons cornstarch, 1 tablespoon lemon juice, and 1 teaspoon vanilla extract. Toss gently until the fruit is evenly coated, then scrape it all into a 2-quart baking dish.
The fruit will look glossy and start to release a little juice while you make the topping. That brief rest helps the cornstarch dissolve, so do not rush it.
Step 2: Mix the Biscuit Dough
In a medium bowl, whisk together 1 1/2 cups flour, 1/4 cup sugar, 1 1/2 teaspoons baking powder, and 1/4 teaspoon salt. Drop in the 1/2 cup cold butter pieces and use a pastry blender or your fingertips to cut the butter into the flour until the mixture looks like coarse meal with some pea-sized bits remaining.
Pour in 2/3 cup cold cream and stir with a fork just until a shaggy dough forms. Stop the moment the dough comes together; overmixing makes the biscuits tough.
Step 3: Drop the Biscuit Dough
Spoon mounds of the dough directly on top of the fruit, spacing them evenly. Brush the tops with an extra tablespoon of cream and shower them with coarse or raw sugar.
The dough will spread as it bakes, so leave a few gaps for the fruit to peek through. Those exposed spots will caramelize around the edges and look beautiful.
Step 4: Bake and Serve Warm
Slide the dish into the oven and bake until the topping is deep golden and the fruit is thick and bubbly, 35 to 40 minutes. Let it cool on a rack for at least 15 minutes, then spoon into bowls and serve warm. A scoop of vanilla ice cream on top never hurts.
How to Nail It Every Time
- Use stone-cold butter and cream straight from the fridge. The butter steams in the oven, creating those flaky layers.
- Taste your peaches before adding sugar. If they are very sweet, back off a tablespoon or two of the sugar in the filling.
- For a thicker filling, add an extra teaspoon of cornstarch if your fruit seems particularly juicy.
- Let the cobbler rest for 15 minutes after baking so the filling can set. Serve warm, not blazing hot.
Storing Leftovers
- Refrigerate: cover tightly and keep up to 3 days.
- Reheating: warm in a 350°F (175°C) oven for 10 to 15 minutes to recrisp the topping. A microwave works in a pinch but will soften the biscuit.
Frequently Asked Questions
Can I use frozen fruit?
Yes. Do not thaw the fruit first, and increase the bake time by 5 to 10 minutes. The filling may be a bit juicier.
Can I make this gluten-free?
Yes. Use a 1:1 gluten-free flour blend with xanthan gum. The topping will be a little more tender, so handle the dough lightly.
Can I make it dairy-free?
Yes. Swap the butter for a solid vegan butter and the cream for full-fat oat or coconut milk. The top will still brown and crisp.
Can I prepare it ahead?
The fruit filling and biscuit dough can be made a few hours ahead. Keep them separate in the fridge, then assemble and bake right before serving.
