Strawberry Dump Cake Recipe

Strawberry dump cake is the dessert I make when people are coming over, and I haven’t left myself any time to cook. You tip diced strawberries into a dish, scatter a buttery cake-mix crumble over the top, and the oven does the rest.

There’s no mixer and only one bowl to wash, and the one thing that makes or breaks it is how you handle the cake mix. I’ll come back to that, because a dry, powdery top is the most common way I see this one go wrong.

Why You’ll Love This Recipe

• It’s a ten-minute job to get in the oven; dice the berries, fork together the topping, spread it, bake.
• You get two textures from five ingredients, a crisp golden crumble over a soft, jammy strawberry layer that eats more like a cobbler than a layer cake.
• Fresh strawberries are the star here, the same berries that make a good baked strawberry cheesecake, but with no crust and no chilling time to wait on.
• It feeds a crowd from one 9×13 dish, which makes it an easy thing to carry to a potluck.
• Everything in it is vegetarian, so the only thing to check is that whatever you spoon on top is too.

Ingredients You’ll Need

You’ll need all the ingredients in the photograph below.

• Fresh strawberries. You need about two quarts, washed and diced. Dicing matters more than it sounds, because big halved berries stay watery in the middle while diced ones cook down into a proper jammy layer.
• Sugar and salt. A quarter cup of sugar and a quarter teaspoon of salt, sprinkled straight over the berries. They pull juice out of the strawberries as the cake bakes, which keeps the topping from sitting on a dry fruit layer.
• Yellow cake mix. One box, any brand. Yellow is my default because it lets the strawberries lead, but white, chocolate, or a strawberry cake mix all work if you want to change the character.
• Unsalted melted butter. Half a cup, melted. Melting it and forking it through the dry mix first is what saves you from the dry, powdery patches most dump cakes end up with.

How to Make Strawberry Dump Cake

Here’s the overview. The recipe card below has the exact amounts and the step-by-step.

Prep the strawberries

Heat the oven to 350°F (180°C). Wash and dice the strawberries, tip them into a 9×13 baking dish, and sprinkle the sugar and salt evenly over the top. Spread them out rather than heaping them in the center, so they bake evenly.

Make the crumble topping

In a bowl, pour the melted butter over the dry cake mix and work it together with a fork until it clumps into coarse crumbles. You’re not making a smooth batter; you want loose, buttery lumps. Dry cake mix scattered over fruit and dotted with butter is what leaves those chalky patches on top, and mixing the butter in first stops that before it starts.

Assemble and bake

Scatter the crumble evenly over the strawberries, covering as much of the surface as you can. A few berries peeking through is fine.

Bake for 45 minutes, until the top is golden and the fruit is bubbling around the edges. Let it sit before serving, or the fruit layer runs instead of settling.

Recipe Notes and Expert Tips

• Cover the surface, then patch the bald spots. If any dry mix is still visible after you spread the crumble, dot those spots with a little extra butter before it goes in. That’s the fix for the dry-topping problem people hit most.
• Don’t stir the layers. Keep the fruit on the bottom and the crumble on top the whole way through. Stirring turns it into a sludgy single layer instead of a cake over fruit.
• Judge it by the edges, not the clock. It’s done when the top is evenly golden, and you can see strawberry juice bubbling at the sides, which may take a few minutes longer than 45 depending on your oven.
• A little lemon lifts it. A squeeze of fresh lemon juice or some zest over the berries sharpens the sweetness, which helps if your strawberries are very sweet or a bit flat.

Recipe Variations

• Frozen strawberries are a tested stand-in for fresh. Thaw them first and drain the liquid that comes off, or the extra water leaves the middle soggy; the sugar and salt stay the same.
• Strawberry pie filling, two cans in place of the fresh fruit, is a tested shortcut for when berries aren’t in season. The filling sets firmer and tastes sweeter than fresh strawberries, so you trade a little fresh flavor for a more dependable layer.
• Peaches, cherries, and other berries are tested swaps as well. Diced peaches give you a peach dump cake, strawberries and peaches together make a good summer version, and blueberries or raspberries work stirred in with the strawberries. Keep the total fruit near the same two quarts.
• Strawberry and rhubarb is a natural pairing, but I haven’t tested a rhubarb version here. Rhubarb is tart and releases a lot of water, so it would need extra sugar and probably a longer bake, and I won’t give amounts I haven’t checked myself.

How to Store Leftovers

Leftovers keep in the fridge for up to 4 days. Let the cake cool first, then transfer it to an airtight container or cover the dish tightly with foil. Reheat single portions in the microwave for 20 to 30 seconds, which is enough to take the chill off without drying the topping.

I’ll bake it a few hours ahead and leave it at room temperature until dessert, then warm portions before serving. Don’t leave leftovers sitting out overnight, though; once it has cooled, the fridge is the right place for it.

What to Serve With Strawberry Dump Cake

This is a warm-dessert kind of cake, and it’s at its best with something cold alongside. A scoop of vanilla ice cream is the classic move, melting down into the hot fruit, and softly whipped cream does the same job if you want it lighter.

If you like a stronger berry hit, spoon over a little extra homemade strawberry sauce, the one I make for cheesecake, poured warm over the ice cream.

It’s the easy, feed-everyone option at the end of a summer meal, which is exactly the slot classic strawberry shortcake fills if you’d rather have the berries in a lighter, less sweet form.
