Pro Tips
Store leftovers in an airtight container. This dump cake needs to be refrigerated once it has been baked and cooled. The fruit in the cake will spoil fast if left on the counter. You can refrigerate it for up to 5 days.
Recipe FAQs
Once set, the fruit filling should be gooey and thick, like a cobbler, but definitely not runny.
