If you don't usually have yellow cake mix in your pantry, you might need to pick some up at the supermarket. This ingredient is essential for the recipe as it forms the base of the cake.

Ingredients For Blueberry Dump Cake Recipe
Blueberries: These can be fresh or frozen and provide the fruity base for the cake.
Yellow cake mix: This boxed mix forms the main structure of the cake and adds sweetness and texture.
Melted butter: This is poured over the cake mix to create a rich, golden topping.
Technique Tip for This Recipe
When preparing this blueberry dump cake, ensure that the blueberries are spread out evenly in the baking dish to create a uniform layer. This will help the cake mix to absorb the juices from the blueberries as it bakes, resulting in a more flavorful and moist cake. Additionally, when pouring the melted butter over the cake mix, try to cover as much of the surface as possible to ensure an even, golden-brown crust.

How to Store / Freeze This Cake
Allow the blueberry dump cake to cool completely at room temperature. This helps to prevent condensation, which can make the cake soggy.
Once cooled, cover the baking dish tightly with plastic wrap or aluminum foil. Alternatively, you can transfer the cake to an airtight container.
Store the covered cake in the refrigerator. It will stay fresh for up to 4-5 days.
For longer storage, consider freezing. First, cut the cake into individual portions. This makes it easier to thaw and reheat only what you need.
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 its freshness.
When ready to enjoy, thaw the cake portions in the refrigerator overnight. This slow thawing process helps maintain the texture and flavor.
To reheat, preheat your oven to 350°F (175°C). Place the thawed cake portions on a baking sheet and cover them with aluminum foil to prevent drying out. Warm in the oven for about 10-15 minutes, or until heated through.
For a quicker option, you can also reheat individual portions in the microwave. Place a portion on a microwave-safe plate and heat on medium power for 1-2 minutes, or until warmed through. Be cautious not to overheat, as this can make the cake rubbery.
Enjoy your blueberry dump cake with a scoop of vanilla ice cream or a dollop of whipped cream for an extra treat!
How to Reheat Leftovers
- Preheat your oven to 350°F (175°C). Place the blueberry dump cake in an oven-safe dish, cover it with aluminum foil to prevent it from drying out, and bake for about 15-20 minutes or until warmed through.
- For a quicker option, use the microwave. Place a portion of the cake on a microwave-safe plate, cover it with a microwave-safe lid or another plate to retain moisture, and heat on medium power for 1-2 minutes. Check and add more time if necessary, in 30-second increments.
- If you prefer a crispy top, use a toaster oven. Preheat it to 350°F (175°C), place the cake on a baking sheet, and heat for about 10-15 minutes until the top is golden and the blueberries are bubbly.
- For an indulgent twist, reheat a slice in a skillet. Melt a small amount of butter over medium heat, add the cake, and cook for 3-5 minutes on each side until warmed through and slightly caramelized.
