Tessa’s Recipe Rundown
Taste: Sweet, juicy blueberries with a hint of bright lemon and vanilla cake flavor.
Texture: Soft, jammy blueberries topped with a thin yet fluffy, cake-like topping that’s lightly crisp around the edges.
Ease: There are a few steps and dishes, but nothing here is difficult.
Why you’ll love this recipe: It’s an easy, crowd-pleasing dessert that makes the most of fresh or frozen blueberries.
This Blueberry Cobbler recipe is everything I want in a summer dessert: juicy blueberries, a soft, cakey topping, and a big scoop of ice cream.
I absolutely love my Blueberry Pie recipe, but it’s definitely more of a weekend project. I wanted to create a blueberry recipe with the same fresh, summery blueberry flavor, but one that was much easier to throw together for a weeknight dessert.
I thought this would be a super straightforward recipe to nail down.
I was wrong.
This blueberry cobbler took more than 15 batches to get right, baked across three different kitchens in three different states. After hearing from readers who wanted a thicker topping and better substitution options, I worked with my team and kept testing until we landed on a cobbler I’m genuinely excited to share with you.
So while you only need one batch to make it, a whole lot of testing went into making sure it’s worth your blueberries.
I made this last night and it was absolutely delicious. It was easy to make. Cobbler crust was not too thick like a biscuit; it was perfect for the blueberries. So glad I found this recipe. It’s a keeper.
Ingredient NOtes
Blueberries – I love using a mix of both regular and wild blueberries for the best taste and texture. You can use fresh or frozen blueberries, but don’t thaw frozen berries first.
Buttermilk – This gives the topping the best flavor and texture.
- Swap: If you need a substitute, use an equal amount of full-fat, plain Greek yogurt and follow the recipe notes for baking. I don’t recommend DIY buttermilk, as it produces a thinner batter and topping.
Baking powder – Helps lift and lighten the cobbler topping. Learn how to test for freshness in my Baking Soda vs. Baking Powder article.
Cornstarch – Helps thicken the blueberry filling. Skip it if using fresh blueberries.
Lemon – The zest and fresh juice from a lemon naturally enhance the flavor of the blueberries, giving it a bright burst of freshness.
- Not a fan? Omit the zest and reduce the juice to 1/2 tablespoon.
Cinnamon – Just a hint of warmth, which complements the blueberries perfectly.
Storage
Leftovers: Store in an airtight container at cool room temperature for up to 2 days or in the fridge for up to 4 days. To reheat, cover the pan with foil and bake at 375°F for about 15 minutes, or until heated through. It’s also delicious cold!
Freezing: I don’t recommend freezing this cobbler, as it can alter the texture. For the best results, make it the day you plan to serve it.
Frequently Asked Questions
Yes! You can use either, and you don’t need to thaw frozen blueberries first. I love using a mix of regular and wild blueberries for the best flavor and texture, but you can use all regular blueberries if that’s what you have. If using fresh blueberries, wash and dry them first and discard any stems.
Wild blueberries have a more intense, slightly tart blueberry flavor and contain less water than regular blueberries, which helps the filling set up nicely. Their smaller size also means more blueberries in every bite! You can usually find frozen wild blueberries in the frozen fruit section.
Buttermilk gives this cobbler the best flavor and texture. If you need a substitute, use an equal amount of full-fat plain Greek yogurt and follow the recipe notes for baking. I do not recommend DIY buttermilk, which results in a thin batter that spreads into the berries.
I haven’t tested this recipe with other fruit, so I can’t recommend a 1:1 swap. Different fruits release different amounts of moisture and may require changes to the sugar, cornstarch, or bake time.
Use a 9×13-inch glass pan or ceramic baking dish. I don’t recommend a metal pan because the acidity from the blueberries and lemon can react with the metal and create an unpleasant metallic flavor.
Yes! Halve the recipe, bake in an 8×8-inch glass pan, and shave a few minutes off the recommended bake time.
If using frozen blueberries, don’t skip the cornstarch, which helps thicken the extra juices they release. Fresh blueberries don’t need cornstarch. Most importantly, bake the cobbler until the filling is bubbling and let it cool before serving so the juices have time to thicken.
The topping can look golden before it’s fully baked, especially in the center. Check several spots with a toothpick, since one spot may be hiding underbaked batter! It’s okay if the toothpick has blueberry juice on it, but it shouldn’t have wet batter. If the topping still looks slightly wet after removing the foil, bake for 1–2 minutes more, uncovered.
For the best taste and texture, make this cobbler the day you plan to serve it. If needed, you can refrigerate leftovers for up to 4 days and reheat them in the oven.

Ingredients
For the batter:
- 5 tablespoons (71 grams) unsalted butter
- 1 1/4 cup (296 grams) buttermilk, or full-fat, plain Greek yogurt, cold¹
- 1 1/4 teaspoon vanilla extract
- 1 1/4 cup (159 grams) all-purpose flour
- 1 1/4 cup (250 grams) granulated sugar
- 2 3/4 teaspoons baking powder
- ¾ teaspoon fine sea salt
For the filling:
- 4 cups (560 grams) blueberries, don’t thaw if frozen
- 2 cups (280 grams) wild blueberries, don’t thaw if frozen²
- 1/2 cup (100 grams) granulated sugar
- 4 tablespoons (32 grams) cornstarch³
- 1 heaping teaspoon fresh lemon zest
- 1 tablespoon fresh lemon juice⁴
- 1/4 teaspoon ground cinnamon
- 1/4 teaspoon fine sea salt
- Coarse sugar, for topping, optional
Instructions
- Preheat the oven to 375°F. Generously spray a 9×13 glass⁵ or ceramic pan with baking spray.
Make the batter:
- In a small heatproof bowl, melt the butter. Set aside to cool until just warm to the touch (about 75°F).
- In a medium bowl, whisk together the cooled butter, buttermilk, and vanilla until combined. In a separate medium bowl, whisk together the flour, sugar, baking powder, and salt. Add the wet mixture to the dry mixture, whisking until combined and no clumps are visible. Set aside for 10 minutes to thicken.
Make the filling:
- In a large bowl, toss the blueberries with the sugar, cornstarch (if using frozen berries), lemon zest, lemon juice, cinnamon, and salt. Break up any cornstarch clumps as you mix.
Assemble:
- Spread blueberry mixture evenly into the prepared pan. Dollop the batter evenly over the blueberries, then spread gently to cover. Sprinkle coarse sugar evenly over batter, if using.
- For frozen berries: Bake uncovered for 40 minutes, then tent with foil and bake for 15–20 minutes more. For fresh berries: Tent with foil after about 25 minutes, then bake for another 25 minutes, or until done. The topping will look golden before it’s fully baked, so check several spots with a toothpick. It’s okay if there’s blueberry juice on the toothpick. If the topping still looks slightly wet, bake uncovered for 1–2 minutes more.
- Let the cobbler cool until just warm before serving, about 45 minutes. The topping will be thin and lightly crisp while warm, then soften and thicken as it cools.
Notes
- Buttermilk gives this cobbler the best flavor and texture. If you need a substitute, use an equal amount of full-fat plain Greek yogurt. The batter will be thicker and the topping denser, with slightly crispier edges. Tent with foil after 25 minutes and bake for another 30-35 minutes, checking with toothpick as written. Milk mixed with vinegar or lemon juice does NOT work and will result in a runny batter that bleeds into the filling.
- If you don’t have wild blueberries, use a total of 6 cups (840 grams, or approx 2 ½ pints) of regular blueberries.
- If using fresh blueberries, do not add cornstarch.
- If you’re not a fan of lemon, simply omit the zest and reduce the juice to 1/2 tablespoon.
- Metal pans can react to the acidity in the blueberries and lemon, giving an unpleasant metallic taste. Use a glass or ceramic pan for this recipe.

My sister made this for our monthly movie night, and it was delicious!! We couldn’t stop eating it. The vanilla cake topping is so soft, and the blueberry filling is perfectly sweet. We’ll be making this every blueberry season for sure!
I didnt care for the cake on top. I think itd be better as a crisp. The filling was tasty however.
Made this last night and it is delicious! My in-laws, husband, and daughter raved about it, too. I ended up using 4 C. wild blueberries and 2 C. peaches, because I wanted that mix and that was what I had on hand. Didn’t change anything else in the recipe. It turned out perfect!
Well the flavor was delicious! I did add a touch more sugar. But like some of the others my crust was not great. It also did not get thick. It all went down into the berries. Seems like there was too many berries for the amount of crust.
I’m not sure what I did wrong- but the 1 cup of flour, 1 cup of milk yielded a soupy batter… it wasn’t thick- rather it was runny and it sank into the blueberry mixture
Hi Lucy! Oh no, I’m sorry to hear that this cobbler didn’t turn out as it should! How old is your baking powder? If your baking powder is not fresh, it can’t do its job and cause all sorts of issues, such as your cobbler topping failing to set up and sinking. Leavening agents can also lose their effectiveness long before the expiration date on the packaging. Tessa talks about the science behind leavening agents, and how to test for leavener freshness, in this article here. I also highly recommend using real buttermilk here whenever possible – especially full fat buttermilk if you can find it (Target typically sells it). Real buttermilk helps this cobbler topping thicken, for a fantastic texture, and gives a wonderful flavor too. I hope you’ll give this cobbler another try – it really is delicious!
I made this last night and it was absolutely delicious. It was easy to make. Cobbler crust was not too thick like a biscuit; it was perfect for the blueberries. So glad I found this recipe. It’s a keeper.
Delicious and easy to make! Frozen blueberries can also be good in this recipe or not?
Hi Angela! We actually tested this recipe using frozen blueberries, so we know they work great! As mentioned in the recipe, if using frozen berries, don’t thaw them prior to baking. I hope that helps! Happy baking 🙂
Followed the recipe to a T (using weight not volume) using frozen berries that I’d previously picked. I was a little worried about the amount of liquid, since they’d accumulated a bit of ice in the freezer, but it did not affect the consistency. Baked for 45 minutes on convection and did not need any extra time. The flavor was perfect – absolutely delicious and rave reviews from my guests! However I deducted 1 star because the topping was much more liquid as what was pictured before baking, and then it did not rise in the oven. I used real buttermilk purchased just for this recipe AND tested my baking powder, and my house is climate controlled. The overall result was quite thin and flat (no more than 1″ max across the bottom of the pan) and was better served with a spatula than a spoon.
Cobbler tasted absolutely delicious! Although my batter sunk into the filling and was not that distinct layer like in your photo, any idea what went wrong?
Hi Carly! We’re so glad to hear that your cobbler was delicious! It’s so hard to say exactly what went wrong with your cobbler without having baked alongside you, but here are a couple initial thoughts:
– While we did include some substitution tips if you don’t have buttermilk, using real buttermilk will yield the best results and help the cake part thicken beautifully. Definitely give the real thing a try next time, if you didn’t this time 🙂
– How do you measure your ingredients? By volume (using cups), or by weight (using a digital kitchen scale)? When measuring by volume, it’s so easy to mis-measure ingredients (particularly flour) and throw off the entire chemistry of a recipe. Check out Tessa’s article here, where she talks about how to best measure ingredients to ensure accuracy every time.
– How old is your baking powder? If your baking powder isn’t fresh, this can cause a whole bunch of issues. Tessa talks about the science behind leavening agents, and how to test for leavener freshness, in this article here!
I hope something here helped, Carly! Happy baking 🙂
Mine too!
I have used this batter recipe with many fruits. I’ve used whole milk and buttermilk. I’ve used self-raising flour and AP flour. It’s all the same. Batter is too thing. I think ratio of 1c milk and 1c flour is not a good ratio if you’re wanting a thicker crust or a crust that doesn’t mix with berries. I would suggest 1/4c more flour with same milk. It will be a bit thicker thus it dripping or mixing with berries. It really depends on how you like your cobblers.. mixed or crustier topping and l do prefer SR flour and I’m not a fan of buttermilk flavor in my crust so l prefer whole milk. I haven’t tried but I do wonder how half’n-half would work. That would be an experiment to try.
Hi just tried this recipe last night and it was delicious! I used whole milk and added 1/4 cup extra flour as the mix seemed to be too soupy. Thanks for this users recommendation it came out perfect to me and my loved ones!
I would like to make this in a smaller 8 x 8 pan. how do you adjust this recipe? thank you. Bonnie
Hi Bonnie! Yes, you can make a half batch – instructions for this in the pink tip box above the recipe 🙂 Let us know what you think once you’ve given this cobbler a try 🙂
