Lemon Blueberry Dump Cake
Use fresh or frozen blueberries and a box of lemon cake mix to make lemon blueberry dump cake! It tastes just like a homemade cobbler. No mixing or additional bowls needed for this dump cake with blueberries.
One of my favorite things about living in Michigan are the fruit farms! We’re only 30 minutes away from multiple pumpkin patches, apple orchards, and berry farms!
Blueberry picking in July has become an annual tradition now and I can’t wait to make this lemon blueberry dump cake with the biggest, freshest blueberries!
But It’s awesome that this lemon dump cake works with frozen or fresh blueberries – both ways will yield a delicious berry citrus cake!
What is a dump cake?
A dump cake is known for ease because you dump ingredients into the cake pan. Most dump cakes are made in 9×13 inch pans. Most dump cakes use fruit or canned pumpkin – although I have my eye on a chocolate dump cake I want to make! Lastly, dump cakes are known for sprinkling a box of dry cake mix over the ingredients in the pan and then adding melted butter.
It’s magical what happens inside the oven. Even I was like “Is this going to work??”
The result is a cobbler like dessert with fruit pieces and cake mixed together! It’s not the type of cake you cut into neat squares, just scoop it onto your plate and eat!
How to make lemon blueberry dump cake:
- Add 2 cups of blueberries to the bottom of a 9×13 inch pan.
- Sprinkle sugar and the lemon zest over the blueberries.
- Sprinkle the dry cake mix evenly over the blueberries.
- Drizzle melted butter evenly over the dry cake.
- Add 1 cup of blueberries on top of the cake. And bake – that’s it!
How do you know when a dump cake is done baking?
Unlike traditional cakes, the toothpick method won’t work for a dump cake. The top of the dump cake should look golden in color and look and feel like a “crust”. But once you break the the crust, the cake will be moist.
Can dump cake be made ahead of time? / How to store dump cake?
Most people prefer a warm dump cake, since it does resemble a cobbler. So with that in mind, yes, you can make a dump cake with blueberries ahead of time, but I would recommend not making it more than 1 day in advance.
Store a dump cake made with fresh or frozen fruit in the fridge covered with a cake pan lid or in a tupperware container.

Where have you found a lemon gluten free cake mix? What brand? I can’t seem to find any of the regular brands I use to carry a lemon gf mix.
Hi Victoria! Aldi carries a gluten free lemon cake mix seasonly! You could also substitute a GF yellow cake mix and add 3 tbsp lemon zest instead of just 1 tbsp lemon zest.
You could probably add some lemon extract to a yellow cake mix. I don’t know how much but I’d add a teaspoon or two, mix and taste. If you can’t taste it, double it up.
Do you think drizzling melted butter over the top is better than slicing cold butter and evenly place it on top? I was just worried some of the cake mix wouldn’t get any butter and be floury cake mix in top
Drizzling melting butter vs cold butter squares – it’s pretty much achieving the same result! The cold butter will melt while baking. I find it easier to just slice the cold butter instead of heating it up first. One less dish to clean!
What I’ve been doing with these is to melt the butter and put the cake mix into a bowl and pour the butter in to the bowl and make it all into a nice crumble and then spread the crumble all over the berries/ fruit that I’m using and then bake as usual.
That sounds like a great method too!
I made this with a boatload of fresh blueberries, light brown sugar, yellow cake mix, the additional of culinary lavender, extra lemon zest and coconut oil instead of the butter. REALLY good.
Can I change this recipe up with a chocolate cake and cherry pie filling?
I’m hesitant to say yes because I personally haven’t tried it, but dump cakes are pretty hard to screw up so I *think* it could work!
