Can I use fresh, frozen, or strawberry pie filling?
Yes. This recipe works with all three. The only thing that changes is the sugar and whether you add a touch of thickener for very juicy fruit.
Do I thaw frozen strawberries first?
No. Use frozen strawberries straight from the freezer. Thawing can make the filling extra watery and more likely to bubble over.
How much sugar should I add for each strawberry type?
- Fresh strawberries: add 1/4 cup granulated sugar (up to 1/3 cup if your berries are very tart).
- Frozen strawberries: add 2 to 3 tablespoons granulated sugar. Frozen fruit releases more liquid, so you will also use a little cornstarch in the recipe.
- Strawberry pie filling: add no extra sugar. It is already sweetened and thickened.
How do I tell dump cake is done when the berries are very juicy?
Look for these three signs:
- Bubbling: you should see steady bubbles around the edges and a few bubbles breaking through near the center.
- No dry powder: the cake mix should not look dusty white anywhere. If you spot dry patches, drizzle 1 to 2 tablespoons of melted butter over those spots and bake 5 to 10 minutes more.
- Golden top: the topping should be mostly golden brown with darker toasted spots.
If the top browns quickly but the fruit is still not bubbling, loosely tent with foil and keep baking until the filling is clearly simmering.
Why is my dump cake still powdery on top?
Usually the butter was not spread evenly enough to moisten the dry mix. Next time, slice butter thinly and cover the surface well, or drizzle evenly with melted butter. You can also gently press the cake mix into an even layer before adding butter.
Do I need to stir the cake mix into the strawberries?
Nope. That would turn it into something closer to a batter-style cake. For dump cake, you keep distinct layers: fruit on bottom, dry mix on top, then butter.
What cake mix flavor works best with strawberry?
Yellow cake mix is classic. White cake mix is a little lighter. Strawberry cake mix can be fun and extra pink, but it is often sweeter, so keep the added sugar modest if you go that route.
