4 Ingredient Blueberry Cobbler

This 4 Ingredient Blueberry Cobbler is so flavorful and easy to whip up with minimal prep time. Combine yellow cake mix, butter, sugar, and blueberries (fresh or frozen), and you will get a perfect, easy blueberry cobbler every time. Serve it with a scoop of vanilla ice cream for a delicious treat!

This easy blueberry cobbler recipe is very similar to a dump cake (like this lemon blueberry dump cake) in that just 4 ingredients are combined in a baking dish and baked until the fruit is bubbling up the sides and the cobbler topping is a nice golden brown.

It may not be your traditional cobbler made with dollops of biscuit dough on top, but it’s certainly just as delicious! Plus, if you can skip the trip to the grocery store freezer section and whip up this easy, homemade, not-really-from-scratch 4-ingredient blueberry cobbler in minutes- it’s totally worth it!

It’s the kind of thing you make when you want to serve up a delicious dessert with minimal effort and zero stress. 

Right up there with my favorite blueberry desserts like blueberry delight, blueberry fluff salad, and lemon blueberry bread pudding, it is even easier to make than them all as well! 

Ingredients for 4 Ingredient Blueberry Cobbler

This section includes ingredient notes and substitution options. Get all measurements, ingredients, and instructions in the printable recipe card at the end of this post.

• Frozen or fresh blueberries – No need to thaw them first. Just dump them in while frozen. 
• Granulated sugar – Mixing the blueberries with the sugar helps to break down the fruit, giving it sweetness, extra juiciness, and a syrupy consistency. 
• Butter – Melt in a saucepan or a microwave-safe dish. When mixed with the cake mix, it forms a crumble with a “cobbled” appearance. Use salted or unsalted butter, the choice is yours. I use salted if it is on hand since a bit of added salt helps to offset the sweetness.
• Box cake mix – I used yellow cake mix, but white cake mix or lemon cake mix would be a great option as well.

How to Make a 4-Ingredient Berry Cobbler

This section shows you how to make the recipe with step-by-step photos and instructions. For the full printable recipe, see the recipe card below. 

Step 1: Add blueberries and sugar to the baking dish and stir gently to coat the blueberries.

Step 2: In a medium bowl, stir the melted butter with the cake mix until combined and becomes crumbly.

Step 3: Sprinkle the buttery cake mix over the blueberries.

Step 4: Bake in a preheated oven at 350F for 40 minutes until golden brown and bubbly.

Storage

Refrigerator: Store leftovers in an airtight container for up to 3 days.

How to Reheat: If you have enough to make it worth your while to use the oven, you can reheat it at 300 degrees. If it’s a single serving, heat it in the microwave for about 30 seconds.

Additions and variations

• Swap the cake mix flavor.  You could also use a French vanilla cake mix, lemon cake mix, white cake mix, spiced cake mix, or even chocolate cake mix if you’d like.
• Add vanilla extract. I like doing this during the fall and winter months. The warm flavor enhancer adds extra coziness.
• Use fresh blueberries. Frozen blueberries are already washed, picked over, and frozen at peak ripeness, but if it’s the middle of blueberry season, you can’t not use fresh blueberries!
• You could also try a different fruit filling. Blackberry cobbler, strawberry cobbler, raspberry cobbler, or whatever frozen or fresh fruit you have on hand.
• Or! If it’s not blueberry season, by all means, use canned blueberry pie filling instead of fresh berries. Juicy blueberries are tasty no matter what!
