Blueberry Dump Cake
So you want dessert. Like, right now. But the idea of multiple bowls, precise measurements, or “cream butter and sugar until fluffy” makes you want to lie down? Say less. Blueberry Dump Cake is here to save the day.
You literally dump everything into a pan, bake it, and somehow end up with a warm, bubbly, cake-meets-cobbler situation that tastes way better than the effort involved. Honestly, it feels illegal.
Why This Recipe Is Awesome
Let’s be real—this recipe is famous for a reason.
- No mixing bowls (your sink will thank you)
- No fancy skills required
- Works for last-minute guests or emergency dessert cravings
- Warm, gooey blueberries + buttery cake topping = unbeatable combo
Also, it’s almost impossible to mess up. Even if you do something “wrong,” it somehow still tastes amazing. That’s elite dessert behavior.
Ingredients You’ll Need
Short list. Big flavor. Minimal thinking.
- Blueberry pie filling – canned or homemade, both are fair game
- Crushed pineapple (optional) – adds sweetness and moisture
- Yellow cake mix – straight from the box, no shame
- Butter – sliced thin or melted
- Cinnamon – optional, but cozy
- Vanilla extract – optional, but why not
That’s it. Five-ish ingredients. You’re already winning.
Step-by-Step Instructions
- Preheat the oven.
Set it to 350°F (175°C). Grease a baking dish. Do not skip this unless you enjoy scraping. - Dump the blueberry filling.
Spread it evenly across the bottom of the dish. This is your fruity foundation. - Add pineapple (if using).
Spoon it over the blueberries and spread gently. Totally optional, but surprisingly good. - Sprinkle the cake mix.
Dump the dry cake mix evenly over the fruit. Do not stir. I repeat—do not stir. - Add butter.
Lay thin slices of butter all over the top, or drizzle melted butter evenly. Try to cover as much surface area as possible. - Add extras.
Sprinkle cinnamon or drizzle vanilla if using. This is the “chef touch.” - Bake.
Bake for 40–45 minutes, until the top is golden and the edges are bubbling like a happy dessert volcano. - Cool slightly.
Let it sit for 10–15 minutes. It thickens up and becomes easier to serve.
Common Mistakes to Avoid
- Stirring everything together.
This is not a regular cake. Trust the dump process. - Using cold, thick butter chunks.
Uneven butter = dry patches. Thin slices or melted works best. - Skipping grease on the pan.
Dump cake shouldn’t dump you into dish-scrubbing misery. - Underbaking.
If the top looks powdery, it’s not done yet. - Overthinking it.
This recipe thrives on chaos. Relax.
Alternatives & Substitutions
Dump cake is basically a free-for-all.
- Fruit swaps:
Cherry, peach, apple, or mixed berries all work beautifully. - Cake mix options:
White cake, lemon cake, or butter cake change the vibe completely. - Butter alternatives:
Margarine works, but butter tastes better. Always. - Add-ins:
Chopped nuts, shredded coconut, or white chocolate chips for texture. - Less sweet version:
Use unsweetened blueberries and a reduced-sugar cake mix.
