This easy Labor Day dessert is the kind of back-pocket recipe that earns a permanent place in late-summer cooking because it relies on a boxed lemon cake mix and a few pantry and freezer staples to make a bright, buttery fruit cobbler-style bake with almost no prep. It fits right into the classic American dump-cake tradition, where layered ingredients bake together into a dessert with a jammy fruit base and a golden cake topping, making it especially handy when you want something festive for a cookout without turning dessert into a project.
Serve this warm with vanilla ice cream, whipped cream, or a spoonful of lightly sweetened Greek yogurt if you want a tangy contrast. For a Labor Day spread, it pairs nicely after grilled burgers, barbecue chicken, or pulled pork, and a side of fresh berries or iced tea helps balance the sweet lemon flavor.
4-Ingredient Oven Baked Lemon Dump Cake
Servings: 8
Ingredients
1 box lemon cake mix, dry and unprepared
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch oven-safe glass baking dish.
2. Spread the lemon pie filling evenly across the bottom of the baking dish.
3. Sprinkle the dry lemon cake mix evenly over the pie filling, covering the surface from edge to edge without stirring.
4. Scatter the shredded coconut over the cake mix, then drizzle the melted butter as evenly as possible over the top so most of the dry mix is moistened.
5. Bake for 45 to 50 minutes, until the top is golden and the filling is bubbling around the edges.
6. Let the dessert rest for 10 to 15 minutes before serving so the filling can settle slightly, then scoop into bowls and serve warm.
Variations & Tips
Add berries: A layer of blueberries or raspberries over the lemon pie filling gives this dessert more color and a nice sweet-tart contrast. Frozen berries work well; just add them straight from the freezer so they do not bleed too much before baking.
Use nuts for crunch: If you like a little texture, replace part of the coconut with chopped pecans or sliced almonds. They toast nicely on top and make the finished dessert feel a bit more special for a holiday table.
Watch for dry spots: Dump cakes bake best when the butter is distributed evenly. If you see patches of dry cake mix before it goes into the oven, drizzle an extra tablespoon or two of melted butter over those areas so the topping bakes up more uniformly.
Serve it warm, not piping hot: Letting the dessert stand briefly after baking helps the lemon filling thicken slightly and makes scooping easier. It will still be warm enough to melt ice cream, but the portions will hold together better.
Try a citrus twist: If you want an even brighter flavor, add a little fresh lemon zest over the top right before serving. It wakes up the boxed cake mix flavor and makes the whole dessert taste fresher.
