We are always looking for quick, easy dessert recipes, and this blackberry cake mix cobbler is one of our favorites.  

It gets the name dump cake because the blackberry filling and store-bought cake mix are simply poured into a baking dish, topped with melted butter, and baked until golden brown.

We like to use lemon cake mix for this recipe, as the flavors of lemon and blackberry go so well together, but you can use yellow or vanilla cake mix if you prefer.  

The recipe uses blackberry pie filling, but if blackberries are in season, you can add fresh berries as well.

The cake is delicious, both hot or cold, and can be served on its own or topped with a scoop of ice cream or a dollop of fresh whipped cream.

Ingredients & Substitutions

For a full list of ingredients and measurements, see the printable recipe card at the bottom of this post.

Blackberry pie filling – You will want 2 cans of blackberry pie filling for this recipe.  You can add a few cups of fresh blackberries, a tablespoon of lemon juice or some lemon zest, or additional fruit such as raspberries, strawberries, or blueberries if you want to play with the flavors.

Cake mix – We like using lemon cake mix with our blackberry dump cake recipe, as the lemon flavor pairs well with the sweet blackberries.  But you can make this cobbler with any flavor of cake mix you have on hand; yellow or vanilla work very well. 

Butter – You will need a full cup of butter for this recipe; you can use salted or unsalted.  The recipe works best with melted butter as it ensures the cake mix will cook up without any dry spots, but you can slice cold butter into thin pats and distribute them over the top of the cake if you like.  They will melt as the cake cooks, however this method sometimes produces a few drier spots.

Place the cake in the oven and bake for 50-55 minutes until the top of the cake is golden brown.

Allow the cake to cool for about 10 minutes before serving as this will help the warm fruit filling set making it easier to serve.

Serving Suggestions

We like to keep things simple and serve this easy blackberry dump cake with a scoop of vanilla ice cream.  This is especially delicous when the cake is served warm and the ice cream can melt into the warm, gooey fruit filling.

You could also add a dollop of Cool Whip, or some fresh whipped cream.

​It is also great topped with some fresh juicy berries.
