Tips For Success

  • The best flavor and texture come from using fresh blackberries. If fresh blackberries are not available, frozen blackberries may be substituted; just remember to defrost them first and drain any extra liquid.
  • You can change the sweetness of the blackberries by adding more or less sugar. Before adding sugar, taste the blackberries to gauge their level of natural sweetness.
  • Before adding the cake mix, sprinkle a little cinnamon or nutmeg over the blackberries for flavor.
  • For the greatest flavor and texture, serve the dump cake warm or at room temperature.

1. Can I use a different fruit for this dump cake?

Absolutely! While this recipe features blackberries, you can substitute them with other fruits such as blueberries, raspberries, or a combination of berries. Adjust the sweetness accordingly based on the natural sweetness of the fruit you choose.

2. Can I use a different cake mix flavor?

Yes, you can experiment with different cake mix flavors to add variety to your dump cake. Yellow cake mix works well with the blackberries, but you can try flavors like white cake, lemon cake, or even chocolate cake for different flavor combinations.

3. Can I make this dump cake ahead of time?

While this dump cake is best enjoyed fresh, you can prepare it a few hours in advance and leave it at room temperature until ready to serve. However, keep in mind that the texture may become slightly softer as time goes by.

4. Can I refrigerate the leftovers?

Yes, you can refrigerate the leftovers in an airtight container for up to 2–3 days. The cake may become denser when chilled, but you can reheat individual servings in the microwave for a few seconds to restore some of the warmth and softness.

5. Can I freeze the dump cake?

This dump cake is not ideal for freezing, as the texture may become mushy when thawed. It is best enjoyed fresh or stored in the refrigerator for a few days.
