What You’ll Need
This recipe relies on simple, readily available ingredients, making it perfect for even the most novice bakers. You’ll need:
- One (15 ounce) can lemon cake mix: The foundation of our delicious dessert, providing the perfect base for the lemon flavor.
- One (15 ounce) can crushed pineapple, undrained: Adds moisture and a touch of tropical sweetness that beautifully complements the lemon.
- Four large eggs: Bind the cake together and add richness.
- One cup buttermilk: Adds moisture and tang, enhancing the overall flavor profile.
- One cup granulated sugar: Provides the sweetness to balance the tartness of the lemon.
- One cup all-purpose flour: Part of the delightful crumb topping.
- One-half cup (one stick) unsalted butter, cold and cut into cubes: Creates a wonderfully crumbly and buttery topping.
- One teaspoon ground cinnamon: Adds warmth and complexity to the topping.
- One-half teaspoon ground nutmeg: A touch of warmth to enhance the cinnamon.
- Lemon zest (from one lemon): Freshly grated lemon zest provides an extra zing of lemon flavor.
Step-by-Step Instructions
This easy lemon dump cake recipe truly lives up to its name; it’s all about dumping and mixing! Here’s how to make it:
- Preheat and Prep: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. This prevents sticking and ensures easy removal.
- Combine Wet Ingredients: In a large bowl, combine the lemon cake mix, undrained crushed pineapple, eggs, and buttermilk. Mix until just combined; don’t overmix. Overmixing can lead to a tough cake.
- Pour into Pan: Pour the batter into the prepared baking pan and spread evenly. Try to create an even layer for consistent baking.
- Make the Crumble Topping: In a separate bowl, whisk together the granulated sugar, flour, cold butter cubes, cinnamon, and nutmeg. Use a pastry blender or your fingers to cut the butter into the dry ingredients until the mixture resembles coarse crumbs. Avoid overmixing the crumble topping; you want it to be slightly chunky.
- Sprinkle & Zest: Evenly sprinkle the crumble topping over the batter. Grate the zest of one lemon directly over the crumble topping for an extra burst of fresh lemon flavor. The zest adds aromatic notes and a beautiful pop of color.
- Bake: Bake for 35-40 minutes, or until a wooden skewer inserted into the center comes out clean. Keep an eye on it during the last 10 minutes, as ovens can vary.
- Cool and Serve: Let the cake cool in the pan for at least 30 minutes before serving. This allows the cake to set and makes it easier to cut into slices.
Tips for Success
For the perfect lemon dump cake, here are a few extra tips: Don’t overmix the batter; this can lead to a tough cake. Make sure your butter is very cold when you make the crumble topping; this will ensure a flaky, crumbly texture. Don’t be afraid to add a little extra lemon zest if you love that bright, citrusy flavor! If your cake starts to brown too quickly on top, loosely cover it with aluminum foil for the remaining baking time. Let the cake cool completely before slicing and serving to prevent it from crumbling. And finally, remember to have fun! Baking should be enjoyable.
Variations to Try
Feel free to experiment with this recipe! Try substituting the lemon cake mix with a different flavor, such as a lime or orange cake mix for a twist. For a richer flavor, use melted butter instead of cold butter cubes in the topping. To make it gluten-free, use a gluten-free cake mix and gluten-free flour. Add a tablespoon of poppy seeds or chopped nuts to the crumble topping for added texture and flavor. If you like a bit of spice, add a pinch of ginger or cardamom to the topping. Get creative and make this recipe your own!

Storing and Reheating
Store leftover lemon dump cake in an airtight container at room temperature for up to 3 days. For longer storage, wrap the cake tightly in plastic wrap and then aluminum foil, and freeze for up to 2 months. To reheat, thaw overnight in the refrigerator. You can then reheat individual slices in the microwave for 20-30 seconds, or in a preheated oven at 350°F (175°C) for 5-7 minutes, until warmed through. Freezing and reheating might slightly alter the texture, but the taste remains delightful.
