If you don't usually keep yellow cake mix in your pantry, you'll need to pick up a box from the baking aisle of your local supermarket.

Ingredients For Blueberry Dump Cake Recipe
Blueberries: Fresh or frozen, these provide the fruity base for the cake.
Yellow cake mix: This is the dry mix that forms the cake layer when combined with butter.
Butter: Melted butter is drizzled over the cake mix to create a rich, golden topping.
Technique Tip for This Recipe
When drizzling the melted butter over the cake mix, make sure to distribute it as evenly as possible. This ensures that the cake bakes uniformly and develops a consistent golden brown crust. If you notice any dry spots on the cake mix before baking, gently spread the butter with a spoon to cover those areas.

How To Store / Freeze This Dessert
Allow the blueberry dump cake to cool completely at room temperature 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 4-5 days.
If you prefer to freeze the dessert, first cut it into individual portions. This makes it easier to thaw only what you need later.
Wrap each portion tightly in plastic wrap, then place them in a resealable freezer bag or an airtight container. Label the container 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. Place the portion on a microwave-safe plate and heat it on a low setting for 1-2 minutes, checking frequently to avoid overheating.
To reheat the entire cake, preheat your oven to 350°F (175°C). Place the cake in an oven-safe dish and cover it with aluminum foil. Heat for about 15-20 minutes or until warmed through.
For an extra touch, serve your reheated blueberry dump cake with a scoop of vanilla ice cream or a dollop of whipped cream. The contrast between the warm cake and the cold topping is simply divine!
How To Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover blueberry dump cake in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Heat for about 15-20 minutes or until warmed through. This method helps maintain the cake's texture and ensures the blueberries remain juicy.
Microwave Method: Transfer a portion of the blueberry dump cake to a microwave-safe plate. Cover it with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 1-2 minutes, checking halfway through to ensure it heats evenly. This is a quick method but may slightly alter the texture of the cake.
Stovetop Method: Place a non-stick skillet over low heat. Add a small amount of butter to the skillet to prevent sticking. Place a portion of the blueberry dump cake in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through to ensure even warming. This method can give the cake a slightly crispy edge while keeping the inside moist.
Air Fryer Method: Preheat your air fryer to 320°F (160°C). Place the leftover blueberry dump cake in the air fryer basket, ensuring it is spread out evenly. Heat for about 5-7 minutes, checking halfway through. This method can help retain the cake's crispiness while warming it thoroughly.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the blueberry dump cake on a piece of aluminum foil or a toaster oven-safe dish. Heat for about 10-15 minutes or until warmed through. This method is convenient and helps maintain the cake's texture.
