Ingredients for Lemon Blueberry Dump Cake

1 (21 oz) can Lucky Leaf Blueberry Pie Filling: This rich, delicious filling is the star of our cake. Feel free to substitute with homemade blueberry compote if you want a personalized touch.
1 (15.25 oz) box Duncan Hines Signature Lemon Supreme Cake Mix: The fragrant, lemony scent of this cake mix infuses our dessert with the tang it needs. If you’d like to experiment, vanilla or yellow cake mix can be intriguing swaps.
1 (8 oz) block Philadelphia Cream Cheese, cubed: The cream cheese adds a layer of richness that cuts through the sweetness. Low-fat cream cheese offers a lighter option while still delivering flavor.
1/2 cup (1 stick) Land O’Lakes Butter, sliced: The butter creates a rich golden crust and brings everything together in buttery embrace. You can use margarine as a cholesterol-free alternative.

How to Make Lemon Blueberry Dump Cake

Preheat your oven to 350°F and grease your 9×13 baking dish thoroughly to ensure the cake comes out effortlessly after baking.
Spread the Lucky Leaf Blueberry Pie Filling evenly across the bottom of the prepared dish. Let the vibrant blue hues flood your kitchen with their sweet, fruity scent.
Scatter the small cubes of Philadelphia Cream Cheese evenly over the blueberries, allowing for pockets of creamy goodness in every bite.
Sprinkle the dry Duncan Hines Lemon Cake Mix generously over the top. Use your hands or a spatula to cover the blueberries completely, creating a protective layer.
Cover the cake mix with the thin slices of Land O’Lakes butter. Place them strategically to ensure that the butter melts evenly, creating a perfect topping as it bakes.
Bake for 40-45 minutes until the top turns a glorious golden brown. The smell wafting through your home will be nothing short of heavenly, beckoning everyone to come and indulge.

Chef’s Notes & Helpful Tips

Make-ahead tips: You can assemble the cake ingredients a day prior and store them in the fridge, then bake right before serving.
Cooking alternatives: For a quicker option, consider using an air fryer. Just reduce the time by 10-15 minutes and monitor closely for that inviting golden hue.
Customization ideas: Try adding crushed nuts on top for a delightful crunch, or incorporate a swirl of lemon curd for an extra zing of flavor.

Common Mistakes to Avoid

Skipping the greasing step can lead to a beautiful yet frustrating mess. Always generously grease your baking dish.
Not distributing the cream cheese evenly leads to uneven melting. Ensure every blueberry garnishes itself with a bit of creaminess!
Overbaking can lead to a dry texture. Keep an eye on your cake during the final minutes to prevent this mishap.
