I love making and eating fruit-based desserts. I have some favorite three and four-ingredient recipes that can be made quickly and easily if I have unexpected guests over. I love peaches and this easy peach cobbler recipe is my most popular recipe on Pinterest. This cherry and pineapple dump cake is also a family favorite!
Why I love this recipe
- Easy Weeknight Recipe: Pantry staples and just a few minutes of prep make this the answer to busy family dinners or unexpected cravings.
- Kid-Pleasing Flavor: Sweet fresh blackberries are a guaranteed hit, even for picky eaters. Plus, "dumping" ingredients is fun! It's a great recipe for kids to help with.
- Fresh fruit with sugar - no cooking down needed: This recipe uses fresh blackberries purchased on sale. I love using fresh fruit when it's affordable and available. Add some cake mix, and butter and it's ready to bake.
- Warm, Delicious Comfort Food: Golden brown crumble topping and juicy fruit filling create a delicious, flavorful dessert.
Yes, this recipe uses fresh blackberries. I find they go on sale regularly and then I buy a few containers.
Yellow Cake mix - I like using Betty Crocker or Dunkin Hines cake mixes. Stock up when they are on sale! I usually use the two brands mentioned, however if you have a different favorite, use it!
1 cup granulated sugar - If the fresh blackberries don't taste sweet, add another quarter cup.
1 ½ sticks of butter - that's ¾ of a pound or 12 teaspoons. I use salted butter, but unsalted will work too.
You'll need to cut them into thin slices, so cut when the butter is still cold.
5 of the 6 oz containers (or approx. 6 cups) fresh blackberry fruit.
I use a 9 x 13 baking dish sprayed with nonstick spray.
Preheat your oven to 350° F
Spray your casserole dish with nonstick baking spray.
Dump the fresh blackberries as the first layer.
Evenly spread granulated sugar on the berries.
I challenge you not to try one of these cherries! Of course, you need to taste test : ).
Add the cake mix on top of the cherries. You want an even thin layer. Just the dry cake mix. Do NOT use the other ingredients listed on the box. Do not stir!
I gently smooth the cake mixture with the back of a spoon. This prevents dry cake mix lumps.
Slice the stick and a half of butter into thin slices. The more slices you have, the better your topping is!
Bake in the oven for approximately 35 minutes until the topping is golden brown. There are usually spots where the blackberry and sugar bubbles up.
Like in the picture below!
Look at the end result below! Yum!
Check 5 minutes before it's finished baking. If there are dry spots, spray some non stick spray on the dry spots. Bake 5 minutes and the dry spots will be gone.
White cake mix with the blackberry fruit tastes superb together. You'll love the flavor!
No, you don't add the ingredients written on the box. Use the dry cake mix straight from the box. It feels weird the first time you do it but that's how these dump cakes are made!
How to store and reheat
Stores well in the refrigerator for four days if wrapped or in a sealed container.
This easy cobbler recipe can be frozen, but that may affect the texture of the curst. Since this is such a quick and easy recipe to make, I would only freeze it if it's because you have leftovers (not because you are trying to make it ahead). Thaw to room temperature and bake for 15 minutes at 350 degrees before serving.
If reheating individual portions, microwaving works well.
Easy Blackberry Dump Cake (with fresh berries)
- 30 oz blackberries approx. 6 cups
- 1 cup sugar a little more if berries are not sweet
- 1 box yellow cake mix
- 1½ stick butter salted or unsalted
- Preheat oven to 350 degrees Fahrenheit.
- Spray 9 x 13 baking dish with no-stick spray.
- Dump cleaned fresh blackberries into the baking dish.
- Spread sugar on top of blackberries, being careful to spread evenly. If blackberries are a little sour, increase sugar used by ¼ cup (1 ¼ cup total).
- Spread cake mix evenly over the blackberries. You are using the dry cake mix with no additional ingredients.
- Thinly slice one and a half sticks of butter (¾ pound). The more slices, the better! Spread them on top of the cake mix.
- DO NOT STIR.
- Bake for 30-40 minutes. Watch for the color to be a delicious golden color.
- If you notice at 30 minutes that there is dry cake mix, take it out of the oven and spray a bit of non-stick spray on the dry parts. Put it back in the oven for a few minutes (3 to 5 minutes).
- Remove when done and let it sit for 5 minutes. Serve with ice cream or whipped cream
