Why You’ll Love This Blackberry Cobbler

  • Thick, syrupy filling: As the berries bake, they release their sweet juices. The cornstarch in the recipe thickens those juices up, creating an incredible syrup to coat the berries.
  • The best topping: A simple cake mix topping adds a golden, buttery layer on top that is completely irresistible.
  • Quick and easy: With just 6 ingredients and 15 minutes of active time, this blackberry cobbler is perfect for your busiest summer days.
  • Flexible: My family has been making this recipe for years and it can be used with many different kinds of summer fruit. You can swap the blackberries out for whichever berries you choose. You could even add fresh sliced peaches.

Ingredient Notes

  • Blackberries – Fresh, not frozen! You can use any berries you’d like.
  • Granulated sugar – Light brown sugar would also work.
  • Cornstarch – As the cobbler bakes, the berries release their juices. The cornstarch works to thicken the juice, so you get this sweet, syrupy filling.
  • Boxed yellow or vanilla cake mix – Using boxed cake mix makes this filling SO easy!
  • Butter – I like using unsalted butter, but you can use salted butter instead.
  • Ice cream – I feel like you can’t have blackberry cobbler without vanilla ice cream. Whipped cream would be great, too.

Can I use other kinds of berries?

Totally! Raspberries or blueberries would be great. So would some combination of all of the above (maybe throw in a few strawberries while you’re at it). Have a look at my Skillet Berry Cobbler and this Classic Berry Cobbler, too. They both use a mixture of berries.

Not a berry person? You can use whatever fruit you’d like here. Consider fresh, diced peaches or nectarines.

How to Make Blackberry Cobbler

  • Prep. Preheat the oven to 350°F and grease a 9”X13” baking dish with butter.
  • Make the blackberry filling. Toss the blackberries with the sugar and cornstarch and spread them over the bottom of the baking dish.
  • Make the topping. Whisk together the cake mix and cinnamon and sprinkle it over the berries. Layer the butter slices over the top.
  • Bake. Bake for 40-45 minutes.

Tips for the Best Blackberry Cobbler

  • Fresh berries. When possible, opt for fresh berries. The texture and flavor is just so much better. If you do use frozen berries, allow the fruit to thaw completely and then drain any excess water from them.
  • Sweetness check. Make sure to pick ripe, sweet berries. If you find yourself with exceptionally sweet blackberries, you may want to reduce the sugar. If your berries are on the tart side, add more sugar to taste.
  • Coat those berries. When tossing the berries with the sugar and cornstarch, make sure they are thoroughly coated. If you just dump it all into the baking dish, you’ll end up with an unevenly sweet cobbler, and the cornstarch won’t thicken the berry juices uniformly.
  • Serve warm. Let the cobbler sit for 10 minutes or so before serving. You want it to be warm but not piping hot. This resting time will give the flavors extra time to meld and the cobbler a little time to set.

How to Serve It

I like topping mine with strawberries and raspberries, a dusting of powdered sugar, and sometimes even a dollop of whipped cream. And, of course, you have to add a scoop of vanilla ice cream! The way the ice cream melts into the warm cobbler is to die for.

Storing and Reheating Extras

  • Store in the fridge: If you find yourself with leftover blackberry cobbler, seal it in an airtight container and store it in your fridge for up to 5 days.
  • To reheat: One of many great things about this cobbler is that leftovers are great cold, at room temperature, or reheated. If you’d like to reheat your leftovers, transfer them to a baking dish, cover with aluminum foil, and bake at 350°F for 10-15 minutes or until heated through.
