Make the most of those juicy summer blueberries with this Blueberry Cobbler recipe! It’s a quick and easy dessert, perfect with a scoop of ice cream.
Cobblers and crisps are the most requested dessert around here. I usually make cobbler with a biscuit topping (Buttermilk Biscuit Strawberry Cobbler! Cherry Cobbler! Peach Cobbler! ahem), but my husband has been a huge fan of cake-like cobblers ever since I made him a Peach Cobbler in the Crockpot.
He says it reminds him of a cake his late grandma used to make, so I whip this up when I want to be extra nice to him 😉 I don’t know if this is a more old school and traditional way to make cobbler, but I don’t even care that much about technicalities. It’s a nice change from our usual biscuit topped fruit desserts!
Ingredients you’ll need
Here is a visual overview of the ingredients in the recipe. Scroll down to the printable recipe card at the bottom of this post for quantities!
- Butter: I recommend using real butter. Buttery spread will not work as well. If using margarine, only use stick margarine. The taste will be different.
- Blueberries: Fresh and frozen work. See notes below for using frozen.
- Buttermilk: If out of buttermilk, make a homemade buttermilk replacement: Stir 1 teaspoon white vinegar into 2 cups of regular milk. Let sit on counter for 5 minutes, then stir well and use as directed in the recipe.

Using frozen berries
To counteract the extra liquid from the frozen berries, you’ll need to add less liquid to the filling – there are instructions in the recipe below.
If you have homegrown and home-frozen blueberries and see a lot of ice crystals/small blocks among the berries, you should also add an extra spoonful of cornstarch.
Cooking the blueberries
I know, a lot of cobbler recipes use the berries raw in the filling. And while that’s easier to prep, I definitely prefer pre-cooking the filling here (it only takes a couple of minutes!).
With the cake-like topping, it’s necessary to bring the berries to a boil with some cornstarch and sugar before adding them to the baking dish.
That way you also know if you added enough sugar (as it can be hard to judge how sweet berries are before cooking them).
Troubleshooting the filling
If your filling doesn’t thicken after bubbling up on the stove, you will need to add a little extra cornstarch.
Simply whisk 1 teaspoon of cornstarch into 1-2 tablespoons cold water, then stir the slurry into the blueberry filling and bring it to a boil again until thickened.
Blueberry cobbler FAQs
The best way is to stick a food thermometer into the thickest part of the topping. It should read 200°F to be done. The filling should be bubbly and the topping should look baked, spring back when touched and look golden in color.
Like fruit pies, a cobbler does not need to be refrigerated. Cover the cooled cobbler well, then leave it on the counter for up to 1 day. If you need to keep your cobbler for a longer time, refrigerate it for up to 3 days.
I let cobbler cool between 10-15 minutes, to allow the juices to set and thicken a little and to allow it to cool down. I like cobbler best hot with a scoop of ice cream, but you can also let it cool for longer and serve it warm or at room temperature.
