There is something mighty satisfying about a dessert you can stir together from pantry basics and a little freezer help, especially in the warm months when nobody wants to fuss. This easy baked summer dessert leans on the bright old-fashioned flavor of lemonade concentrate, which melts into a sweet-tart layer as it bakes with cake mix and butter for a cobbler-style treat that feels like the kind of simple family dessert passed around after supper on a hot Midwestern evening.
Serve this warm with scoops of vanilla ice cream, a spoonful of whipped topping, or a dollop of softly whipped cream if you want to dress it up. Fresh berries, sliced strawberries, or a few thin lemon slices on the side make it feel especially summery, and a glass of iced tea or cold coffee pairs nicely with its bright citrus flavor.
4-Ingredient Oven Baked Lemonade Dessert
Servings: 8
Ingredients
1 box yellow cake mix
1 solid unthawed 12-ounce block frozen lemonade concentrate
1 cup lemon-lime soda
1/2 cup unsalted butter, melted
Directions
1. Preheat the oven to 350°F and lightly grease an 8x8-inch or similar small oven-safe glass casserole dish.
2. Pour the lemon-lime soda into the prepared dish, then place the solid unthawed block of frozen lemonade concentrate right in the center.
3. Sprinkle the dry cake mix evenly over the top, covering the liquid and frozen concentrate as much as possible.
4. Drizzle the melted butter as evenly as you can over the cake mix. Do not stir. A few dry spots are fine.
5. Bake for 40 to 45 minutes, until the top is golden and the lemon filling is bubbling around the edges. Let it rest for 10 to 15 minutes before serving so the filling can settle slightly.
Variations & Tips
Berry Version: Scatter 1 cup fresh blueberries or sliced strawberries around the frozen lemonade block before adding the cake mix for a fruity twist that bakes up beautifully with the lemon.
Extra Lemon Flavor: Add 1 teaspoon finely grated lemon zest over the cake mix before drizzling on the butter if you want a brighter, more pronounced citrus flavor.
Texture Tip: If you notice a few very dry patches halfway through baking, drizzle on 1 to 2 more tablespoons melted butter. That little trick helps the topping brown more evenly without needing to stir.
Pan Size Note: This works best in a smaller baking dish so the filling stays nicely spoonable. A larger dish will spread it too thin and can make the dessert bake up drier.
Serving Tip: This dessert is especially good served warm the day it is baked, though leftovers can be covered and refrigerated, then gently reheated for another helping the next day.
