Ingredients for Lemon Blueberry Dump Cake

Gathering the right ingredients is the first step to creating this delightful Lemon Blueberry Dump Cake. Here’s what you’ll need:

Lemon cake mix: This is the star of the show! It provides the base flavor and sweetness. You can use any brand you prefer, but I love the ones that have a hint of zest.
Lemon-lime soda: This bubbly addition adds moisture and a touch of tanginess. It’s a fun twist that keeps the cake light and fluffy. If you’re looking for a healthier option, you can use a diet version.
Fresh or frozen blueberries: These little gems bring a burst of sweetness and color. Fresh blueberries are fantastic, but frozen ones work just as well. Just make sure to thaw and drain them if you go that route.

Unsalted butter: Melted butter adds richness and helps create that golden crust. I always opt for unsalted to control the saltiness in my desserts.

For those who want to get creative, you can substitute blueberries with other berries like raspberries or strawberries. The exact measurements for these ingredients are at the bottom of the article, ready for you to print out and take to the store!

How to Make Lemon Blueberry Dump Cake

Now that you have your ingredients ready, let’s dive into the fun part—making this Lemon Blueberry Dump Cake! Follow these simple steps, and you’ll have a delicious dessert in no time.

Step 1: Preheat the Oven

First things first, preheat your oven to 350°F (175°C). Preheating is crucial because it ensures that your cake bakes evenly. A hot oven helps the cake rise beautifully, giving it that perfect fluffy texture. Trust me, you don’t want to skip this step!

Step 2: Prepare the Blueberries

Next, grab your blueberries and spread them evenly on the bottom of your baking dish. If you’re using fresh blueberries, rinse them gently and pat them dry. For frozen blueberries, make sure to thaw and drain them first. This prevents excess moisture from making your cake soggy. An even layer of blueberries is key to a delightful burst of flavor in every bite!

Step 3: Mix the Cake Batter

In a mixing bowl, combine the lemon cake mix with the lemon-lime soda. Stir gently until just combined. Be careful not to overmix; a few lumps are perfectly fine! Overmixing can lead to a dense cake, and we want it light and airy. The fizz from the soda will help create that lovely texture!

Step 4: Assemble the Cake

Now it’s time to pour the cake batter over the blueberries. Make sure to distribute it evenly across the top. This helps the blueberries stay nestled below the cake, creating a beautiful layer when it bakes. Don’t worry if it looks a bit messy; it’ll all come together in the oven!

Step 5: Add the Butter

Drizzle the melted butter over the cake batter. This step is essential as it adds richness and helps form a golden crust. The butter will melt into the cake as it bakes, creating a deliciously moist texture. Just let it flow over the top; it doesn’t have to be perfect!

Step 6: Bake the Cake

Place your baking dish in the preheated oven and bake for 40-45 minutes. Keep an eye on it as it bakes! You’ll know it’s done when the top is golden brown and a toothpick inserted in the center comes out clean. The aroma will fill your kitchen, making it hard to resist!

Step 7: Cool and Serve

Once baked, remove the cake from the oven and let it cool for a few minutes. This cooling time allows the flavors to settle. Serve it warm, perhaps with a dollop of whipped cream or a scoop of ice cream. Trust me, it’s the perfect finishing touch!

Tips for Success

Use room temperature ingredients for a smoother batter.

Don’t skip the cooling time; it enhances the flavors.
Experiment with different berries for a unique twist.
For a fun presentation, dust with powdered sugar before serving.

Store leftovers in an airtight container to keep it fresh.

Equipment Needed

Baking dish: A 9×13 inch dish works perfectly. You can also use a glass or ceramic dish for even baking.

Mixing bowl: Any large bowl will do. A whisk or spatula is great for mixing.
Measuring cups: Essential for accurate ingredient portions, but you can eyeball it if you’re feeling adventurous!
Oven mitts: Safety first! Protect your hands when taking the cake out of the oven.
