How To Store / Freeze This Dessert
Allow the blueberry dump cake to cool completely before storing. This helps prevent condensation, which can make the cake soggy.
For short-term storage, cover the baking dish tightly with plastic wrap or aluminum foil. You can also transfer the cake to an airtight container. Store it in the refrigerator for up to 3-4 days.
If you want to freeze the dessert, first ensure it is completely cooled. Cut the cake into individual portions for easier thawing and serving later.
Wrap each portion tightly in plastic wrap, then place them in a freezer-safe bag or container. Label with the date to keep track of freshness.
When you're ready to enjoy a frozen piece, thaw it in the refrigerator overnight. For a quicker option, you can use the microwave. Heat on a low setting in 30-second intervals until warmed through.
To reheat the entire cake, preheat your oven to 350°F (175°C). Place the cake in an oven-safe dish and cover with aluminum foil. Heat for about 15-20 minutes, or until warmed through.
For an extra touch, serve the reheated blueberry dump cake with a scoop of vanilla ice cream or a dollop of whipped cream. The contrast of warm cake and cold topping is simply divine.
