Easy Blueberry Cobbler Recipe with Fresh or Frozen Berries

You don’t need fresh blueberries for this.
In fact… frozen might be even better.

The best part? It turns out rich, juicy, and perfectly golden every single time — no matter which berries you use.

There’s something nostalgic about scooping into a warm dish of blueberry cobbler — the bubbly, jammy fruit, the golden buttery topping, and that sweet smell drifting from the oven.

🧑‍🍳 Step-by-Step Instructions

Step 1: Preheat your oven

Preheat your oven to 375°F (190°C). This ensures your cobbler starts baking immediately and cooks evenly.

Step 2: Prepare your baking dish

Use a 9x9-inch baking dish or a 10-inch cast iron skillet. Lightly grease it with butter or non-stick spray to prevent sticking.

Step 3: Make the blueberry filling

In a large mixing bowl, combine:

• Blueberries
• Sugar
• Lemon juice
• Lemon zest (optional)
• Cornstarch
• Vanilla extract

Toss everything gently with a silicone spatula until the berries are evenly coated and the sugar starts to dissolve.

👉 Tip: If using frozen berries, increase the cornstarch to 2½ tablespoons to balance extra liquid.

Pour the berry mixture into the prepared baking dish and spread it out evenly.

Step 4: Make the cobbler topping

In a medium bowl, whisk together:

• Flour
• Baking powder
• Baking soda
• Salt
• Sugar

Add the cold cubed butter. Use a pastry cutter, two forks, or clean fingers to cut the butter into the flour mixture until it resembles coarse crumbs — like wet sand with some pea-sized butter chunks.

Pour in the buttermilk and stir with a fork or spatula until a shaggy dough forms. It should be thick and sticky — don’t overmix.

👉 Important: The dough will not be pourable. It's a biscuit-style topping, so it will be spooned on in chunks.

Step 5: Assemble the cobbler

Using a spoon or cookie scoop, drop the dough in heaping tablespoons over the blueberry filling. The topping will not cover the entire surface — gaps are good! They allow the berry juices to bubble up.

For a little extra texture and sparkle, sprinkle coarse sugar or turbinado sugar on top of the dough mounds (optional, but worth it).

Step 6: Bake the cobbler

Place the dish in the preheated oven and bake for 35 to 40 minutes.

You're looking for:

• A deeply golden brown topping
• Bubbling filling around the edges and in the gaps
• A toothpick inserted into the topping should come out clean

👉 Tip: If the top is browning too quickly but the filling isn’t bubbling yet, loosely tent the dish with foil for the last 10 minutes.

Step 7: Cool slightly before serving

Let the cobbler cool for at least 15–20 minutes before serving. This helps the juices thicken slightly and prevents molten lava burns to the tongue.

❓ FAQs + Troubleshooting

Q: Can I use frozen blueberries?
A: Yes! No need to thaw. Just toss them in and increase cornstarch to 2½ tablespoon to handle the extra moisture.

Q: My topping came out gummy — what happened?
A: This can happen if the dish is too deep or the topping wasn’t baked long enough. Use a wide, shallow dish and make sure the topping is golden and a toothpick comes out clean.

Q: Can I make this in advance?
A: Yes. You can bake it, let it cool completely, and refrigerate it for up to 3 days. Reheat in the oven at 300°F for 15–20 minutes or until warmed through.

Q: Can I double this recipe?
A: Absolutely! Use a 9x13-inch pan, double all ingredients, and add 5–10 minutes to the baking time.
