Instructions

Cake Mix Blackberry Cobbler Recipe

Preheat and Prep

Preheat your oven to 375°F (190°C). Lightly grease your 9×13 inch baking dish with butter or non-stick spray. This ensures your cobbler doesn’t stick and makes cleanup a breeze.

Mix the Berries

In a large bowl, gently toss the blackberries with 1/2 cup of the sugar and the vanilla extract. Let them sit for about 10 minutes to macerate, which helps release their natural juices and enhances the flavor.

Prepare the Cake Mix

In another bowl, combine the cake mix with the remaining 1/2 cup of sugar. Gradually stir in the water and melted butter until the mixture is smooth. This will be your cobbler’s topping, so make sure there are no lumps.

Layer and Bake

Spread the blackberry mixture evenly in the prepared baking dish. Pour the cake mix batter over the berries, covering them as much as possible. Bake for 45 minutes, or until the topping is golden brown and a toothpick inserted comes out clean.

Cool and Serve

Allow the cobbler to cool for at least 15 minutes before serving. This resting period lets the juices thicken slightly, making it easier to serve. Enjoy warm, preferably with a scoop of vanilla ice cream.

Tips and Tricks

For an extra crispy topping, sprinkle a little extra sugar over the cake mix before baking. If you’re using frozen blackberries, no need to thaw them first; just increase the baking time by 5-10 minutes. To prevent the berries from sinking, you can dust them with a tablespoon of flour before adding the cake mix.

Recipe Variations

  • Peach Cobbler Twist: Swap blackberries for peaches and use a white cake mix for a summer classic.
  • Chocolate Berry Delight: Use a chocolate cake mix and mix berries for a decadent twist.
  • Spiced Version: Add cinnamon or nutmeg to the cake mix for a warm, spiced flavor.

Frequently Asked Questions

Can I use a different type of berry?

Absolutely! This recipe is versatile. Raspberries, blueberries, or a mix can substitute for blackberries. Adjust sugar based on the berries’ natural sweetness.

How do I store leftovers?

Cover the cobbler with foil or transfer to an airtight container and refrigerate for up to 3 days. Reheat in the oven or microwave before serving.

Can I make this recipe gluten-free?

Yes, simply use a gluten-free cake mix and ensure all other ingredients are gluten-free. The result will be just as delicious.

This cake mix blackberry cobbler is a foolproof dessert that combines simplicity with decadence. Perfect for any occasion, it’s sure to become a go-to recipe in your collection.
