What is a Lemon Poppy Seed Dump Cake?
At its core, a Lemon Poppy Seed Dump Cake is an easy, one-pan dessert that requires minimal prep. The idea behind a “dump cake” is that you literally “dump” the ingredients into a baking dish, and then let the oven do the magic. It’s one of those rare recipes where the result is far better than the effort put in, making it an ideal choice for those who want a delicious dessert without spending hours in the kitchen.
This Lemon Poppy Seed Dump Cake uses a combination of lemon pie filling, cream cheese, cake mix, and butter, with poppy seeds sprinkled on top for an added texture. The cake emerges from the oven golden brown, with a gooey, citrusy filling that pairs perfectly with a scoop of vanilla ice cream or a dollop of whipped cream.
Ingredients for the Perfect Lemon Poppy Seed Dump Cake
Before we dive into the recipe, let’s take a look at the ingredients that come together to create this delightful dessert.
1. Nonstick Cooking Spray
This simple ingredient ensures that your cake doesn’t stick to the pan, making cleanup a breeze. It’s a must-have for any baking project, especially when you want to avoid a mess.
2. Lemon Pie Filling (21–22 oz)
Lemon pie filling is the star of the show in this dump cake. It provides the rich, tangy lemon flavor and creates the base for the cake. The sweetness and tartness of the pie filling balance each other perfectly, creating a refreshing contrast to the richness of the other ingredients.
3. Yellow or White Cake Mix (15.25 oz)
A box of yellow or white cake mix is used to create the cake layer. This is the base of the cake and adds structure and fluffiness to the dessert. The cake mix blends beautifully with the lemon filling to form the gooey texture of the dump cake.
4. Cream Cheese (4 oz)
Cream cheese adds a rich, creamy texture to the cake and helps to balance the acidity of the lemon. It also adds a luxurious mouthfeel that makes every bite of the cake feel indulgent. Cut the cream cheese into small pieces and spread it evenly over the pie filling to ensure that each slice gets a little creamy goodness.
5. Poppy Seeds (½ teaspoon, optional)
While poppy seeds are optional, they add a delightful crunch and a touch of elegance to the cake. They are typically used in lemon cakes for both flavor and texture. If you enjoy a little extra crunch in your dessert, be sure to sprinkle them generously on top of the cake mix.
6. Butter (¾ cup, thinly sliced)
Butter helps to form a golden, crispy top on the cake. It also ensures the cake remains moist and flavorful. By slicing the butter thinly and placing it evenly across the top, the butter melts into the cake mix and creates a rich, delicious crust.
7. Sweetened Whipped Cream or Vanilla Ice Cream (for serving)
While this is optional, a dollop of sweetened whipped cream or a scoop of vanilla ice cream is the perfect finishing touch to this dessert. The cold, creamy texture complements the warm, gooey cake and enhances the overall experience.

How to Make Lemon Poppy Seed Dump Cake: Step-by-Step Guide
Now that we know the ingredients, let’s walk through the simple steps to create this indulgent dessert.
Step 1: Preheat Your Oven
Set your oven to 350°F (175°C) and allow it to preheat. This ensures the cake bakes evenly. While the oven is heating up, you can start preparing the baking dish and the ingredients.
Step 2: Coat the Baking Dish with Nonstick Cooking Spray
Lightly grease a 9×13-inch baking dish with nonstick cooking spray. This will prevent the cake from sticking to the dish and make it easier to serve later.
Step 3: Spread the Lemon Pie Filling
Open the can of lemon pie filling and spread it evenly across the bottom of the prepared baking dish. This filling will serve as the gooey base of the dump cake.
Step 4: Add the Cream Cheese
Cut the cream cheese into small, even pieces and scatter them evenly over the top of the lemon pie filling. The cream cheese will melt during baking and create pockets of creamy goodness throughout the cake.
Step 5: Sprinkle the Cake Mix
Evenly sprinkle the yellow or white cake mix over the lemon pie filling and cream cheese. Don’t stir or mix the ingredients—just let the cake mix sit on top. It will bake into a beautiful, light, and crumbly cake layer.
Step 6: Add the Poppy Seeds (Optional)
If you’re using poppy seeds, sprinkle them evenly over the cake mix. This step is optional, but if you love the crunch and flavor that poppy seeds bring, it’s highly recommended.
Step 7: Top with Butter
Thinly slice the butter and place the slices evenly over the top of the cake mix. As the cake bakes, the butter will melt and create a deliciously golden, crispy top.
Step 8: Bake
Place the baking dish in the preheated oven and bake for 35 minutes. The cake is done when the top is golden brown, and the filling is bubbly. You’ll know it’s ready when a toothpick inserted into the center comes out clean or with a few moist crumbs.
Step 9: Cool and Serve
Once the cake is baked, allow it to cool slightly for about 5 minutes. This will help the filling set and make it easier to serve. For an extra treat, serve the cake warm with a dollop of whipped cream or a scoop of vanilla ice cream.
Tips for Making the Best Lemon Poppy Seed Dump Cake
- Don’t Overmix: One of the keys to a perfect dump cake is not overmixing the ingredients. The beauty of a dump cake is that it’s meant to be quick and easy. The cake mix should sit on top of the filling without being stirred in.
- Use Full-Fat Cream Cheese: For the best flavor and texture, use full-fat cream cheese. It melts better and provides a creamier texture compared to reduced-fat versions.
- Customize the Flavor: While this recipe is fantastic as-is, you can experiment with other flavors. Try adding a few drops of vanilla extract to the pie filling for an extra depth of flavor or swap the yellow cake mix for lemon cake mix for a more intense citrus taste.
- Serving Suggestions: Serve the Lemon Poppy Seed Dump Cake with a scoop of vanilla ice cream or a dollop of whipped cream for added creaminess. You could also drizzle a little lemon glaze over the top for a zesty finish.
