Blueberry Cobbler Recipe

How to Make Easy Blueberry Cobbler

What is a Cobbler? Is it Different From a Crisp or a Crumble?

Cobblers, crisps, and crumbles are all fruit bases with topping – but the toppings vary. The definitions of each are surprisingly highly-debated regionally. As I see it, here are the differences:

• Cobbler: Fruit base with a biscuit topping, a cake-like topping, or a cake-like base and topping, like my Peach Cobbler.
• Crisp: Fruit base with a namesake topping consisting of flour, sugar, butter, spices, and sometimes oats, which completely covers the fruit – like my Apple Crisp Recipe.
• Crumble: Think streusel topping. No oats, but sometimes there are nuts instead. A crumble topping can be sandy in texture, or made in large clumps, to partially or completely cover the fruit.

Ingredients for Easy Blueberry Cobbler Filling:

• Blueberries – I highly recommend using both regular blueberries and wild blueberries, for the best taste and texture. You can use fresh or frozen blueberries. More on this below.
• Sugar – Granulated, for sweetness and to help make the filling perfectly juicy.
• Cornstarch– To help thicken the blueberry filling. Skip if using fresh blueberries – they don’t need the additional thickening agent. More on this below.
• Lemons – Blueberries and lemons are the perfect pairing, so don’t skip this! Use both the zest and fresh juice for a beautiful burst of freshness in this filling. If you’re not a fan of lemon, simply omit the zest and reduce the juice to 1 tablespoon.
• Cinnamon – This very slight hint of spice complements the blueberries perfectly.
• Salt – I prefer fine sea salt, but you can use table salt. Learn about the differences between salt types here.

Ingredients for Blueberry Cobbler Topping:

• Sugar – Granulated sugar, for sweetness, flavor, moisture, and more. Learn more about all that sugar does in your baking here.
• All-purpose flour – Measured correctly! This cobbler topping is designed to be light and fluffy, and too much flour will ruin that. Use a digital scale for precision.
• Salt – To help balance the sweetness.
• Baking powder – To lift and lighten this cobbler topping. Be sure to use fresh baking powder. Learn how to test for freshness in my Baking Soda vs. Baking Powder article.
• Butter – Use unsalted butter, for flavor and moisture in this cake topping.
• Buttermilk – This brings the best flavor and texture to the cake topping. More on this below.
• Vanilla extract – For flavor.
• Coarse sugar – Optional, but I love the slight crunch this brings to the cobbler.

How to Make Easy Blueberry Cobbler Recipe:

1. Preheat the oven and prepare the baking dish. Preheat the oven to 400°F. Spray a 9×13-inch glass pan with nonstick spray and set aside.
2. Prepare the batter. In a 2-cup measuring glass or medium-sized bowl, stir together the wet ingredients. In a separate medium bowl, whisk together the dry ingredients. Add the wet mixture to the dry mixture, stirring until combined and no clumps are visible. Set aside.
3. Prepare the filling. In a large bowl, toss together all filling ingredients.
4. Assemble. Spread blueberry mixture evenly into the prepared pan. Pour batter on top of the blueberries, carefully spreading across the top of the berries if needed (but don’t worry if it’s not all the way to the edges!). Sprinkle coarse sugar evenly over the batter.
5. Bake. Bake for 45 minutes, or until the top is golden brown and set. Use a toothpick or cake tester in several places to check for doneness. Allow to sit until just warm before serving. Serve fresh with vanilla ice cream or homemade whipped cream.

Should I Use Frozen Blueberries or Fresh Blueberries for This Cobbler Recipe?

You can use either! I have included directions in the recipe for using fresh or frozen blueberries. Don’t thaw if using frozen blueberries. If using fresh blueberries, be sure to wash and dry the berries first, and discard any stems.

Can I Use Regular Blueberries Only, Instead of Regular + Wild Blueberries?

Yes – but you’re missing out! Simply use regular blueberries for the total volume/weight of both wild and regular blueberries listed in the recipe.

Here’s Why I Love Wild Blueberries:

• They have an intensely blueberry flavor with a slight tartness.
• They’re smaller in size, so they fill all the little gaps in the filling so you get MORE blueberries and the filling is held together more uniformly.
• Wild blueberries contain less water, so they help the filling set up perfectly.
• You can find frozen wild blueberries in the frozen fruit section at most grocery stores.

Do I Have to Use Buttermilk?

No – but I highly recommend it. I have included directions for making DIY buttermilk in the instructions, but as demonstrated in my experimenting, nothing compares to real buttermilk. It will yield a thicker, lighter, fluffier topping that sits beautifully on top of the fruit, and it brings a pleasant tang to help balance the sweetness.

Can I Use a Different Fruit?

We haven’t tested this recipe using anything other than blueberries – but let us know in the comments below if you give blackberries, raspberries, or strawberries a try. Just note that the sweetness level and lemon and spice pairing may need some adjustment. Alternatively, check out my Brown Butter Peach Cobbler recipe.

What Pan Should I Use for Blueberry Cobbler?

This is a rare occurrence where I don’t prefer a metal pan! Metal can react to the acidity in the blueberries and lemon, giving an unpleasant metallic taste. We tested this recipe using this 9×13-inch glass pan as well as this ceramic dish. Don’t use a smaller baking dish or your cobbler will overflow.

Can I Halve This Blueberry Cobbler Recipe?

Yes! Halve the recipe, bake in an 8×8-inch glass pan, and shave a few minutes off the recommended bake time.

How Do You Make Blueberry Cobbler Not Runny Or Mushy?

• If using frozen berries, don’t skip the cornstarch. The cornstarch will help thicken those juices that release while baking.
• Be sure to cook it fully, too, as cornstarch doesn’t activate its thickening properties until just over 200°F, so you want the filling to bubble in the oven.
• Cornstarch isn’t needed if using fresh blueberries, as they won’t release as much juice.

How to Store Blueberry Cobbler

To store leftover cobbler, place in an airtight container (or use the lid this pan comes with!) and store in the refrigerator for up to 4 days. Reheating instructions are below, but I also enjoy this cobbler straight from the fridge!

Can You Freeze Blueberry Cobbler?

This recipe isn’t best suited for freezing. For best results, make blueberry cobbler the day you plan to serve. If you need to make this cobbler ahead of time, follow the reheating directions below.

How to Reheat Blueberry Cobbler

To reheat blueberry cobbler leftovers, cover the pan with aluminum foil and bake at 400°F for 10-15 minutes, or until heated through. Reheating in the microwave will result in more of a soggy texture.
