Cast Iron Blueberry Peach Cobbler

Living in Texas, summer always reminds me of childhood trips to Fredericksburg for peaches. I can still remember the excitement of stopping at a familiar roadside stand, where they served the most amazing peach cobbler topped with a scoop of fresh peach ice cream. Those memories inspired this cast iron blueberry peach cobbler recipe. It’s my grown-up take on that classic summer dessert, with the added twist of blueberries for a burst of tangy flavor. While I can’t promise it’ll be quite as good as that roadside stand’s version, I can guarantee it’ll bring a taste of summer to your table, especially when served warm with a scoop of vanilla ice cream. And the best part? It’s so simple to make.

If you love this blueberry peach cobbler, you’ll want to try my other fruit desserts, too. My homemade cherry pie filling makes an excellent base for cherry puff pastry turnovers, and my homemade apple pie filling is perfect for mini puff pastry apple pies. For a different take on breakfast, berry crêpes with a dollop of whipped cream offer a lighter alternative that still satisfies that sweet tooth.

Key Ingredients and Substitutions

This cast-iron blueberry peach cobbler recipe is simple and perfect for summer. With just a few ingredients and your favorite skillet, you’ll have a warm, fruity dessert that everyone will love.

In the printable recipe below, you can find a complete list of ingredients and measurements.

• Peaches: It’s peach season, and we chose to use a combination of fresh Texas peaches that we got on a recent trip to the Texas Hill Country and South Carolina peaches, which are a little less sweet than Texas peaches. 
• Blueberries: These provide bursts of flavor and add a perfect tartness to balance the sweet peaches. Fresh blueberries are ideal, but frozen can work, too – there’s no need to thaw them. Add them frozen and increase the flour slightly to account for the extra juice they’ll release during baking.
• Granulated sugar: We use granulated sugar, but feel free to experiment with brown sugar for a deeper, caramel-like sweetness. Reduce slightly or substitute with honey or maple syrup for a less sweet version.
• All-purpose flour: We added a little flour to thicken the fruit juices as the cobbler baked, but cornstarch can also be used. The flour is also used in the cobbler topping.
• Butter: We used frozen, unsalted butter, cut into small cubes and shredded on a box grater. You can also use cold butter cut into small cubes. We prefer unsalted butter to control the amount of salt added to the recipe.

How to Make Cast-Iron Blueberry Peach Cobbler

Here are the quick, step-by-step instructions with visuals; you can find the full instructions, including the exact ingredients, in the recipe card below.

Pro-tip: There is no need to skin the peaches, but if you prefer to remove the skin, you can blanch them and then peel the skin off before slicing.

1. Prepare the fruit mixture: In a large bowl, combine the blueberries, peaches, sugar, lemon juice, vanilla extract, and flour. Gently toss to coat the fruit evenly, ensuring each piece is coated well. Transfer the fruit mixture to a 10-inch cast-iron skillet, spreading it evenly to create a uniform base for your cobbler.

2. Create the topping: In a medium bowl, whisk together the flour, sugar, baking powder, and salt for the cobbler topping. Add the cold, cubed butter to the flour mixture. We prefer to freeze the butter and then “shred it” using the large holes of a box grater to make it easier to combine it with the flour.  Use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse crumbs. Pour in the buttermilk and stir until just combined. The dough should be slightly sticky and clumpy – this texture is key for a great cobbler topping.

3. Top the cobbler and bake: Drop spoonfuls of the dough over the blueberry peach filling. Aim for even coverage, but don’t worry if some fruit is still visible. Place the skillet in the preheated oven and bake for 35-40 minutes. You’re looking for a golden brown topping and bubbling fruit underneath.

4. Cool slightly: Allow the cobbler to cool for about 10 minutes before serving. This brief rest lets the juices thicken slightly, enhancing flavor and texture.  Enjoy your cobbler warm with a scoop of vanilla ice cream or a dollop of whipped cream.

Make-Ahead and Storage

Make-Ahead: We recommend making this cobbler before serving for the best texture and flavor. However, if you need to prepare the components in advance, you can make the fruit filling and store it separately from the topping. Prepare the fruit mixture and refrigerate in an airtight container for up to 24 hours. Mix the dry ingredients for the topping and store them at room temperature, adding the butter and buttermilk just before baking.

How to Store: This cobbler is best enjoyed fresh, but if you have leftovers, let them cool completely, then transfer them to an airtight container. Store in the refrigerator for up to 2 days, keeping in mind that the topping may lose some of its crispness.  It can also be frozen for up to 

How to Reheat: For individual servings, the cobbler can be reheated in the microwave for 30-45 seconds. To reheat the whole cobbler, transfer it to an oven-safe dish, cover it with foil, and warm it in a 350°F oven for about 20 minutes. Add a scoop of vanilla ice cream before serving for that fresh-baked taste. Allow the frozen cobbler to thaw in the refrigerator overnight before reheating.

Recipe Tips and Notes

• Let it rest. The cobbler should rest for 10 minutes to allow the filling to thicken and set up, making it easier to serve.
• No cast iron skillet? No problem. Don’t worry if you don’t have a cast-iron skillet; use a 9×9″ baking dish instead.
• Fresh versus Frozen Berries. If you are using frozen fruit, allow it to thaw and drain any excess water. It will be a little mushier than fresh, and you might need to increase the amount of flour used to thicken it.
• Prep the Peaches. We don’t mind the skin on our peaches for cobbler, but if you want to remove the skin, you can easily peel them with a paring knife if your peaches are ripe. For firmer peaches, try the blanching method for easy peeling.
• Customize your topping. For an extra layer of flavor, sprinkle cinnamon or nutmeg on the cobbler topping.
• Add more cobbler topping. We like more fruit and less cobbler topping, but you can double the amount if you prefer.
