🥣Serving Tips
- It’s best to serve this dessert warm from the oven.
- If you can’t serve it warm from the oven, this cake also heats up nicely in the microwave.
- Besides enjoying this dump cake as is, everything tastes better topped with fresh whipped cream or even a scoop of vanilla ice cream.
🍶Storage Tips
- Make sure the cake has cooled completely to room temperature.
- Then, cover the cake with plastic wrap or aluminum foil to prevent air from getting in and drying it out.
- Store them in an airtight container in the refrigerator for up to five days.
🔁 Reheating Tips
- To enjoy the cake again, simply place a slice of the cake on a microwave-safe dish and heat it for 30-60 seconds, checking after every 15 seconds or so to make sure it doesn't overcook.
- If you have a larger amount of cake to reheat, the oven may be a better option. Preheat your oven to 350°F and place the cake on a baking sheet or in an oven-safe dish. Cover it with foil to prevent any further browning or drying out, and bake for 10-15 minutes until it's heated through.
- You can also reheat a cake in an air fryer. Preheat the air fryer to 350°F and place the cake in an air fryer basket. Heat for approximately 5-10 minutes, checking frequently to ensure it doesn't overcook.
- Note that the texture of the cake may change slightly when it is refrigerated, but it will still be delicious!

Lynda says
We really enjoyed this recipe. I like the melted butter mixed into the cake mix rather than just putting the butter on top. I added a 1/4 cup of coconut in with the butter and cake mix for a different texture and taste. Thanks for the recipe Lois.
Lois says
Love the idea of adding coconut! Thanks for the great comment!
Sharon Nagel says
The recipe is perfect just the way it is. It's also fun to add extra items. I also like to add the butter in pats on the top and sprinkle with slivered Almonds .
Lois says
That sounds good too! Thank you for visiting.
Amanda says
Do you have to cover with with foil while it bakes? I used a can of blueberry pie filling and one can of lemon pie filling and mixed in fresh blueberries and dollops of cream cheese throughout. With lemon cake mix instead of vanilla.
Lois says
The recipe doesn't call for covering it with aluminum foil while it bakes. Your recipe sounds really different from what I posted, let me know how it turns out!
april says
can you use fresh blueberries?
Lois says
While you could sprinkle fresh blueberries in with the canned blueberry pie filling, you really need the syrup from the pie filling to make this recipe. Thank you for visiting.
Lisa says
Does this need to be refrigerated.
Lois says
Yes, you should refrigerate it if you don't plan to serve it right away as well as the leftovers. Thank you for visiting.
Melisa Woodruff says
Can you use a lemon pound cake mix? Have a box of lemon pound cake mix but would like to try something new besides following the box directions.
Lois says
Hi Melissa, I've never tried a pound cake mix for any of the dump cake recipes. If you do, please come back and let me know how it works out for you! Thanks!
