Ingredients For Blueberry Dump Cake Recipe
Blueberries: Fresh or frozen, these provide the fruity base for the cake.
Yellow cake mix: This dry mix forms the cake layer and adds sweetness and texture.
Butter: Melted butter is drizzled over the cake mix to create a rich, golden crust.
Sugar: Sprinkled over the blueberries to enhance their natural sweetness.
Technique Tip for This Recipe
When spreading the blueberries in the baking dish, make sure they are evenly distributed to ensure consistent flavor in every bite. If using frozen blueberries, there's no need to thaw them; just add a few extra minutes to the baking time. For a more complex flavor, consider mixing in a teaspoon of lemon zest with the sugar before sprinkling it over the blueberries. This will add a subtle citrus note that complements the blueberries beautifully. When drizzling the melted butter over the cake mix, try to cover as much surface area as possible to ensure an even, golden-brown crust.

How to Store or Freeze This Cake
Allow the blueberry dump cake to cool completely at room temperature before storing. This helps prevent condensation, which can make the cake soggy.
Once cooled, cover the baking dish tightly with plastic wrap or aluminum foil. Alternatively, transfer the cake to an airtight container to maintain its freshness.
Store the cake in the refrigerator if you plan to consume it within 3-4 days. The cool temperature helps preserve the blueberries and keeps the cake moist.
For longer storage, consider freezing the blueberry dump cake. Cut the cake into individual portions and wrap each piece tightly in plastic wrap. Then, place the wrapped pieces in a freezer-safe bag or container.
Label the container with the date to keep track of its freshness. The cake can be frozen for up to 3 months without losing its delightful flavor and texture.
When ready to enjoy, thaw the cake in the refrigerator overnight. This gradual thawing process helps maintain the cake's consistency.
To reheat, preheat your oven to 350°F (175°C). Place the thawed cake in an oven-safe dish and cover it with aluminum foil. Warm it in the oven for about 15-20 minutes, or until heated through.
For a quicker option, you can also microwave individual portions. Place a piece of cake on a microwave-safe plate and heat on medium power for 30-60 seconds, or until warm.
Serve the reheated blueberry dump cake with a scoop of vanilla ice cream or a dollop of whipped cream for an extra indulgent treat.
How to Reheat Leftovers
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 flavor.
For a quicker option, use the microwave. Place a portion of the blueberry dump cake on a microwave-safe plate. Cover it with a microwave-safe lid or another plate to keep the moisture in. Heat on medium power for 1-2 minutes, checking halfway through to ensure it doesn't overheat. This method is convenient but may slightly alter the cake's texture.
If you have an air fryer, preheat it to 320°F (160°C). Place the blueberry dump cake in the air fryer basket, ensuring it's not overcrowded. Heat for 5-7 minutes, checking halfway through. This method can help retain a crispy top while warming the cake evenly.
For a stovetop method, use a double boiler. Place the blueberry dump cake in a heatproof bowl over a pot of simmering water. Cover the bowl with foil and heat for about 10-15 minutes, stirring occasionally. This gentle method helps preserve the cake's moisture and flavor.
If you prefer a toaster oven, preheat it to 350°F (175°C). Place the blueberry dump cake in an oven-safe dish and cover with foil. Heat for 10-15 minutes or until warmed through. This method is great for smaller portions and helps maintain the cake's texture.
