Very Berry Blackberry Dump Cake

This Very Berry Blackberry Dump Cake is my favorite recipe to make with fresh spring and summer blackberries. The addition of blackberry or raspberry Jell-O really makes the flavor of this dump cake pop!
Last weekend I made my favorite Very Berry Blackberry Dump Cake and I couldn't wait to share it with y'all. Whenever I have blackberries on hand I always make this recipe or or blackberry cobbler. If I had to make a choice out of the two the dump cake would definitely be the winner. 

Dump cakes aren't anything new, but most recipe are made using canned pie filling. This recipe is a bit different because it uses fresh blackberries and another ingredient that makes this dump cake very berry ...... it's blackberry Jell-O. The addition of the Jell-O really makes the fresh blackberries pop with flavor.

Blackberry fusion Jell-O can sometimes be hard to find, so if you can't find it just use raspberry Jell-O. I got this recipe from a friend 8 years ago and it's one of my favorite cherished recipes. I have this recipe on a tattered piece of paper that has butter spatters all over it. Don't you just love those kind of recipes? I do because you know it's a good. 

This recipe is easy-peasy to make just dump all the ingredients one by one into a 9 x 13 inch baking pan and bake. This recipe is best with fresh blackberries, but you can also use frozen. If using frozen berries, thaw the berries and decrease the water to 1/2 cup or just use the frozen berry juice in place of the water in the recipe.  

I usually bake my dump cake just before or while dinner is cooking. That way the dump cake has time to cool a bit while we eat. The topping gets nice and crunchy as it cools making it perfect by the time dessert rolls around.

Serve with a dollop of whipped cream, cool whip or vanilla ice cream and enjoy!!!

This recipe sounds tremendous. I'm betting peach would be good as well! Thanks for posting this. I have tried dump cakes but have never seen an option for using fresh berries! Love your blog. Always good things going on over here.

Wow, what a great recipe, so easy-peasy too!
Plan on making it this weekend for company. I just hope I can locate the correct jell-o flavor, plus will definitely be using 2 sticks of butter. Butter rules in this house! LOL!!
Thank you for sharing!

This is just what I need.....E-A-S-Y!!!! Seems like you could just about use any kind of berries and match them up with the same jello flavor? Will print this recipe and put in my Mommy's Kitchen binder! Thanks Tina.

What a great post, Tina! You've been kind of quite lately. I hope all is well with you!
@syrupandbiscuits, things are looking up again so I am back in the saddle again with my blog. Something came up so I needed to take a blogging break.

This recipe would be soooo much better if you bought all the ingredients at WALMART!
Looks wonderful! I'd like a piece. :-)
Tanya said…
I would love some of this at this very minute :) Looks delicious!

This was fantastic! I made this when I visited my son and daughter-in-law and only got one small piece. I'm going to half the recipe and make one just for me. Oh, won't that be a great treat for breakfast!
Linda I am so glad you liked it. I half the recipe myself sometimes. When I do half the recipe I use the small jiffy yellow cake mixes. I think it is a 9 oz box.

I have never used water in a dump cake recipe before, can you tell me how to add it? Just pour it over all?
Anonymous said…
Question, could you use the juice from the berrys in with the water to make your 1 1/2 cups needed to make the cake more flavorful?
This was a suggestion on the back of one of those 3 minute lemon microwave cakes and it really gave it a pop of flavor.
Another great recipe.Thanks Shawnie

I just found your web site and it looks awsome. I made your Blackberry dump cake and it was great, everyone loved it. I do have a question, the cake was a little over juicy. Should I add less water the next time I make it.
Tina Butler said…
@mom31271,
Did you use fresh or frozen blackberries? If you used frozen then I would decrease or leave out the water. If you used fresh then maybe just add 1/2 cup.
Michelle said…
At what point do you add the water? Do you mix the jello powder and sugar with the water and then pour over the berries?
Tina Butler said…
@Michelle,
Preheat oven to 350 degrees. Spread berries into a 9 x 13 inch baking pan. Mix jell-O and sugar together and sprinkle over the berries. Sprinkle the cake mix over the jell-o and berries. If using nuts add them now. Pour the melted butter over the cake mix and then slowly add the water.

Has anyone tried this with gluten free cake mix? My daughter loves blackberries but has to eat gluten free. I was wondering if it would work?

Just in case anyone was wondering, I tried it with betty crocker gluten free cake mix and it was delicious.
Tina Butler said…
Thank you for coming back and posting about the gluten free cake mix :)

Did you defrost berry first or do they go in frozen?
Tina Butler said…
I let hem defrost and then added them to the recipe. If using frozen berries make sure to drain off any of the juice before adding them. Also decrease the water to 1/2 cup when using frozen berries or just use 1/2 cup of the frozen berry juice.
Marcia Clark said…
I used 2 1/2 C fresh blackberries and 1 1/2 C chopped fresh Rhubarb. 1 1/2 sticks of butter and it was delicious! Great recipe! Thanks
June said…
A litle confused. First you say an 8 inch square pan in the recipe, then you say a 9X13 pan in your comments. The ingredients seem too much for 8 unch square pan.
Tina Butler said…
It has been fixed to 9x13 in baking pan.

I'm not trying to be difficult as you've already tried to address this question. Does the water go over the cake mix and butter or around the edges of the pan?

Wondering if u tried using canned fruit pie filling?
Tina Butler said…
I have never used anything but fresh or frozen fruit. If you use canned pie filling I cannot guarantee the results.

For the water: Pour the melted butter over the cake mix and then slowly add the water.

I made this tonight and I didn't quite have the right ingredient! (Living in Europe serving the Army) they don't have Raspberry Jello in that size so I used Cherry! Didn't have yellow cake mix on hand so I tried devil's food! All I can say is Yummy!!
Question. Should I refrigerate left overs?
Tayaka said…
Looks and sounds delicious!"

Pleae answer the question abt the water. You keep saying "add the water" but the question that was asked involved whther the water is poured over the cake mix or around the edges. I have never used water in a dump cake and I don't want a soggy crust.
Tina Butler said…
The question has been answered. After pouring the butter you pour the water. It was never stated to add the water to the edges, so add the water all over the top.

Wow! Wow! And.. Wow! This recipe is absolutely the best!! I made it for my Dad's birthday & he LOVED it! He said it was "delicious"; and it was. Thank you so much for sharing this wonderful recipe. It will be the only dump cake recipe I use from now on.

Does the leftover dessert need to be refrigerated?
pam said…
The recipe says 1 stick of butter but, then in the reviews it says 2 sticks of butter ???????
Tina Butler said…
It is one stick (1/2 cup) of melted butter.

I can't wait to make this.
I have a lemon cake mix in my pantry can I use it instead of the yellow or butter cake mix?
Thank you
This is perfect! I want to make a dump cake tonight with fresh raspberries from the farmer's market rather than a canned filling. And my daughter doesn't care for the traditional pineapple in a dump cake. Jello? Brilliant! Thank you!
