You will make this easy blackberry dump cake over and over again! It’s like blackberry cobbler with cake mix, and so easy to make! 

My maternal grandparents farmed in central Missouri on an absolutely gorgeous plot of land. Wooded, rolling hills. Several ponds, and it backed up to a creek where I spent days swimming, fishing and sneaking up on baby crawfish so I could catch them. My grandparents were salt of the earth. They farmed until late in their lives, raising cattle and soybeans and maintaining many acres of woods. My Grandma kept quite the garden, and was a canning and curing pro. She also had huge wild blackberry brambles in abundance. She made a lot of cobblers, and I think she would have loved this easy dump cake recipe!

As a kid with boundless energy, I would be sent to pick buckets and buckets of juicy blackberries. I would pick the blackberries until my legs and arms were scratched beyond recognition, and my face was smeared in juice from sneaking bites.  My Grandma Clara was masterful with the juicy berries; her jam, pies and cobblers could not be beat! She would then preserve as many as possible in her small outhouse cellar so that she could savor this delectable summer fruit year-round.

I think our love of blackberries must be genetic for the women in my family. My Mom makes a killer blackberry cobbler, and if my sister and I ever get to have an opinion on dessert, we beg for something with blackberries! This blackberry dump cake is so very easy, it’s basically like an easy blackberry cobbler with cake mix!

Just five ingredients, and you’re on your way. I have had rave reviews from people all over the country who made this recipe. It’s a delicious mix of blackberry pie and a gooey cookie, without the fuss!

Recipe Substitutions and Additions 

I think a truly easy recipe has plenty of substitutions available! 

  • Instead of the fresh fruit, lemon and brown sugar, feel free to use canned pie filling! You will need about four cups worth of pie filling. 
  • For this recipe, I used a yellow box of cake mix. But you can try other varieties! I chose yellow because it’s a more buttery cake mix. But I know that a white cake mix, or vanilla cake mix would be a great substitute! 
  • Try out mixed berries! Any combination of raspberries, blackberries and fresh blueberries will be delicious.
  • I was pretty stingy with the amount of sugar in the blackberry layer. You can absolutely add up to 1/2 cup of sugar, to your taste!
  • Substitute white sugar for the brown sugar. 
  • Yes, you can use frozen blackberries! Thaw them first and pat them dry thoroughly with paper towels before using. The concern with using frozen fruit is managing the excess water content so the cobbler doesn’t turn out watery and runny!

How to Make Cake Mix Cobbler

It’s easy to make a blackberry dump cobbler!

  • First mix the fresh, rinsed blackberries with the lemon juice. Place them in the bottom of a lightly greased 9×13” baking pan.
  • Add the brown sugar, then the yellow cake mix. Top with the pats of butter. You can also melt the butter and pour the melted butter over the top of the dry cake mix. Don’t stir!
  • Place the pan in the oven and bake until the top is golden brown, and the filling is bubbly! If there are any dry pockets of flour after 20 minutes or so, you can add an extra pat of butter over that section.
  • Remove from the oven and allow to cool 5-10 minutes before serving. Truly one of the easiest desserts you can make!
