You only need a few simple ingredients for this lemon dump cake recipe. You can find them in a grocery store if you don't have these pantry staples:
- Can lemon pie filling or lemon creme filling -- 2 cans of lemon pie filling
- Box yellow cake mix -- any brand of boxed cake mix is fine
- Butter -- salted butter or unsalted butter cut into thin slices
Note -- If you only have 1 can of pie filling, use a square baking dish and half of your box cake mix and enough butter to cover the top of the cake.
How to Make Easy Lemon Dump Cake
First, preheat your oven to 350 degrees f. Then, grease a baking pan with butter or non stick cooking spray.
Spoon the lemon pie filling into the baking dish. Spread the lemon filling evenly on the bottom of the baking dish.
Next, sprinkle the dry cake mix over the pie filling. Gently spread the cake mix evenly over the lemon layer.
Finally, slice a stick of butter and another half stick of butter. Place the thin pats of butter in even rows on top of the cake mix.
You can fill in any gaps with small slivers of butter--just keep the butter pats in a single layer. Butter should cover the entire top of the dry cake mix, and you won't get dry cake mix spots this way.
As the cake bakes, the butter melts into the dry mix and forms a delicious, buttery, super moist crust!
Place the cake into the preheated oven. Bake for 40 to 45 minutes or until the crust is golden brown.
Every oven is different, though, so you may need a few more minutes. You can add more butter during the baking process if there are large dry spots.
After the cake is done baking, remove from the oven and let it cool down a little before serving.
There are a couple great ways to customize this delicious dessert!
Make a lemon cream cheese dump cake by cutting up a block of cream cheese and adding cream cheese cubes on top of the lemon pie filling. It'll add some texture and a mellower flavor to the cake.
Instead of yellow cake mix, use lemon cake mix or vanilla cake mix or white cake mix.
For a lemon blueberry dump cake, you can either use 1 can of blueberry pie filling in place of the lemon pie filling, or simply serve the lemon dump cake with fresh blueberries or puree on top.
You can make your own pie filling or homemade lemon curd in place of canned pie filling.
Serve your dump cake with a scoop of vanilla ice cream, and some Cool Whip, whipped cream, lemon zest, or powdered sugar on top!
How to Store and Reheat
Store any leftover lemon dump cake in an airtight container or covered with plastic wrap. It'll last 3 to 4 days--if you can resist it for that long!
You can leave the cake out at room temperature if your kitchen is cooler, but I like to keep mine refrigerated, as it holds up better.
Enjoy your leftovers cold, room temperature, or reheated lightly in the microwave on low power.
Expert Tips and FAQ
Do not make the cake according to package directions. You are using dry cake mix on top of the lemon filling.
Make sure to spread the cake mix evenly on top of the pie filling so that there are not clumps of dry cake mix along the sides of the cake pan.
I find using slices of butter placed evenly on top of the dump cake works better than pouring melted butter over the cake mix. You won't get dry areas of cake mix this way.
Yes. You can make a dump cake up to a day ahead of time without the top crust getting too soft.
Not always, but it depends on the filling. A 3 ingredient lemon dump cake without cream cheese does not need to be refrigerated, but lemon dump cake with cream cheese should be stored in the refrigerator. If your kitchen is very warm, store the cake in the refrigerator.
