Lemon Blueberry Dump Cake

Lemon Blueberry Dump Cake sounds interesting yet weird. Lemon blueberry sounds elegant, but then adding dump cake to it sounds a little strange, borderline trashy in my honest opinion! I recently discovered dump cakes and now I’m pretty obsessed with them. And now that I know what they consist of, my creative juices are flowing and I can’t stop thinking of the yummy combinations you can try to in order to create a masterpiece dump cake! How is that for an oxymoron?

What Is A Dump Cake?

A dump cake is an incredibly easy way to bake a cake with just a few, not so cake-like ingredients aside from actual cake mix. The best part of dump cakes is that the cake mix is store bought cake mix. Super easy! So what are no so cake-like ingredients? Unlike most cakes, with a dump cake you don’t have to gather up eggs, oil, and water. You will, however, need some kind of juicy fruit and butter. Lots and lots of butter! Don’t get discouraged though. Since these cakes omit the oil, you can add extra butter and feel okay about things. Plus, this makes a 9 x 13 cake. Assuming you are sharing this cake with others, you won’t consume too much of the overall butter!

Fruity Concoctions

When it comes to dump cakes, you can change up the ingredients and mix and match a variety of fruit with different types of cake mixes. When choosing a juicy fruit, it’s a great idea to choose a yummy pie filling flavor or canned fruit such as pineapple. For example, you could make a Pineapple Dump Cake or you could opt for a Cherry Pie Dump Cake. However, in this recipe, we are going to focus on a lemon blueberry dump cake. Sounds amazing!

My first experience with dump cakes came with cherry pie dump cake. I belong to quite a few recipe Facebook groups and a few people were posting about how amazingly yummy and easy dump cakes were. What the heck is a dump cake?? I had never tried one before, but after reading their testimonials, I was certain I needed to give it a shot. The cherry pie dump cake was DELICIOUS! A few weeks later I tried a pineapple dump cake. Guess what? That was YUMMY too! After that, every time I walked down the baking aisle, I found myself checking out the pie filling and cake mix sections to see what I could bake next. I knew I had blueberry pie filling in my pantry so when I saw the lemon cake mix, I thought that combo would be SO AMAZING!

Lemon Blueberry Dump Cake Ingredients

You won’t need flour for this tasty cake. And during the quarantine that Covid-19 brought about, a no-flour cake worked out well. Remember the flour shortages? Yes, those were awful. I mean, it was scary that the meat departments experienced shortages as well, but flour? Yikes! We couldn’t bake whatever we wanted every day, the horror! Even cake mixes weren’t easy to come by for that matter. Some weeks you might be able to grab the last, lonely box of brownie or cake mix and other weeks there was nothing!

One week I spotted a lemon cake mix and came up with the idea for a blueberry dump cake. It sounded delectable and I couldn’t wait to make this super simple, yet fancy dump cake. I love saying fancy dump cake, it sounds so ironic.

Here is everything you will need for this deliciously easy cake:

  • 3/4 stick Butter
  • 2 cans Blueberry Pie Filling
  • 1 box Yellow Cake Mix
  • 1/2 stick butter cubed

Making The Cake

Dump cakes are kind of self-explanatory, you basically just dump the ingredients into a pan and bake them in the oven. In less than an hour, you have a scrumptious cake that you can eat for dessert or as an anytime snack. Nonetheless, you will have to melt some of the butter before dumping the fruit and cake mix into the pan. And you will have to dice up some of the butter, just before you bake the cake in the oven.

Regardless, of needing to do something other than dump and bake, you will find this incredibly easy to make. Just preheat the oven to 350 F degrees. Melt the butter in the pan while the oven warms up. Just pop the pan with butter in the oven for a few minutes. You want the butter to melt in the pan so that you can swirl it around and completely grease the pan with the butter.

Once the pan has been covered with butter, add the blueberry pie filling directly to the pan and spread it out as evenly as you can. Next, sprinkle the cake mix on top of the blueberries. Finally, take the cubed butter and distribute it evenly on top of the cake mix. No need to cover the pan, just put it in the oven and bake it at 350 degrees for 50 minutes or until a toothpick comes clean. Once the cake is done, take it out of the oven to cool for at least 5 to 10 minutes.

The Dump Cake Is Done!

Once your cake is done, you will want want to dig in so you can eat it warm. Control yourself! It will be difficult, but try. Honestly, you don’t want to cut into it too soon, give it a chance to solidify a bit. Trust me, it will be worth it. And, it will still be warm after 5 to 10 minutes. The filling gets extremely hot so it will stay warm for quite some time.

I love to top this (and any dessert for that matter) with home made whipped cream. Hey, if you are going to eat a delicious dessert, don’t skimp on the topping. Go all in and make it scrumptiously worth it!
