- French Vanilla Cake Mix: This shortcut ingredient adds incredible flavor and keeps the process fuss-free. Any vanilla cake mix works, but French vanilla gives a lovely bakery-style aroma.
- Old-Fashioned Oats: The secret to a classic crisp texture and a hint of wholesome chewiness.
- Chopped Walnuts: For nutty richness and an irresistible crunch, but totally optional if you prefer to go nut-free.
- Salted Butter (Melted): Drives everything together, ensuring the topping bakes up golden, crumbly, and full of flavor. Salted butter adds a tasty savory note.

Variations

- Add a Citrus Zing: Mix fresh lemon or orange zest into the berries before topping for a bright, tangy note.
- Different Berries: Toss in any combination of frozen berries, or even frozen cherries or peaches, depending on your mood and what’s in your freezer.
- Mix up the Cake Mix: Swap French vanilla for classic yellow or spice cake mix for a fun twist.
How to Make Berry Crisp Dump Cake
Step 1: Prep the Pan and Berries
Preheat your oven to 350°F. Give a 9×13 baking dish a generous spray with nonstick cooking spray. Scatter the frozen mixed berries evenly across the bottom—no thawing needed.
Step 2: Make the Crisp Topping
In a medium bowl, combine the dry cake mix, old-fashioned oats, chopped walnuts, and melted salted butter. Stir everything until thick, crumbly clumps form—aim for a streusel-like consistency.
Step 3: Top and Bake
Sprinkle the crumbly topping evenly over the berries. Don’t worry if it looks a little rustic—imperfection is part of the charm!
Step 4: Bake to Perfection
Bake for 50–55 minutes, until the topping is beautifully golden and the berries are bubbly and saucy around the sides of the pan. The aroma alone will let you know it’s ready.
Step 5: Serve and Savor
Let the crisp cool just until it won’t burn your tongue. Spoon generous helpings into bowls and, if you’re feeling extra, add a scoop of vanilla bean ice cream. The contrast of hot crisp and cold ice cream is pure bliss!
Pro Tips for Making the Recipe
- Don’t Thaw the Berries: Using berries straight from the freezer ensures a thick, jammy sauce with the ideal consistency.
- Even Topping Distribution: Make sure the crisp topping covers the berries in a single, even layer so every bite gets a bit of everything.
- Let It Cool Briefly: If you slice in immediately, it might be soupy; give it 10–15 minutes to set up a bit!
- Customize Crunch: Mix in some coconut flakes or chocolate chips for extra flavor, especially if serving a crowd with a sweet tooth.
How to Serve

Serve this berry crisp dump cake warm, dished up in bowls so you catch all those bubbling berry juices. It’s simply dreamy with a scoop of vanilla ice cream or a dollop of whipped cream. Love a little contrast? Try pairing with a tangy Greek yogurt for breakfast or brunch—no one says dessert can’t start your day!
Make Ahead and Storage
Storing Leftovers
Cool completely, then cover tightly with foil or transfer to an airtight container. Store in the fridge for up to 3 days.
Freezing
Once cooled, the crisp can be frozen (well wrapped) for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating
Rewarm in a 350°F oven for 15–20 minutes, or microwave individual portions for a quick treat.
FAQs
-
Can I use fresh berries instead of frozen?
Absolutely! Fresh berries work beautifully. You may want to add a tablespoon or two of water to help them release more juices—otherwise, simply follow the same method and keep an eye on the bake time, which may decrease slightly.
-
Can I make this without nuts?
Definitely. Simply leave out the walnuts, or substitute with sunflower seeds or shredded coconut for texture, especially if serving someone with nut allergies.
-
What if I don’t have French vanilla cake mix?
A regular yellow or white cake mix works just as well. The end result will still be sweet, buttery, and satisfying—don’t let the brand or flavor slow you down.
-
Can I prepare this ahead of time?
You can assemble the dish (except for the melted butter) a few hours early and stash it in the fridge. When ready to bake, pour over the butter, add the topping, and bake as directed. It’s best enjoyed fresh for maximum crunch, but leftovers will absolutely hold up for the next day.
