Tips for the Best Dump Cake
- Try to cover as much of the dry cake mix with butter as possible to avoid powdery spots.
- If needed, gently spread the butter with a spoon after pouring. I’ll swirl the butter into the cake mix on dry spots. Just be careful to not mix the blueberry filling too much into the cake mix topping.
- Bake until the top is fully golden and slightly crisp—that’s where the magic happens. Depending on your oven that could take up to 1 hour.
Variations & Add-Ins
Want to switch it up? Here are a few easy ideas:
- Add fresh blueberries for extra texture
- Sprinkle white chocolate chips on top before baking
- Add sliced almonds for a little crunch
- Swap lemon cake mix for vanilla or yellow cake mix
What to Serve With Dump Cake
This dessert is next-level when served warm with:
- Vanilla ice cream
- Whipped cream
- A drizzle of lemon glaze
The cold + warm combo is unbeatable.
Storage & Reheating
- Store covered in the fridge for up to 4 days
- Reheat in the microwave for 30–45 seconds
- You can also enjoy it cold straight from the fridge (it’s honestly so good this way too)
FAQ’s
Can I use salted butter?
Yes, but it will slightly change the flavor. Unsalted gives you more control.
Do I need to mix anything?
Nope! That’s the beauty of a dump cake—just layer and bake.
Can I use homemade blueberry filling?
Absolutely. Just make sure you have about the same amount as two cans.
Why is my cake mix still powdery?
That usually means some areas didn’t get enough butter. Try spreading it more evenly next time.
