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.
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.

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 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
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.
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.
For the water: Pour the melted butter over the cake mix and then slowly add the water.
Question. Should I refrigerate left overs?

I have a lemon cake mix in my pantry can I use it instead of the yellow or butter cake mix?
Thank you
