This 4-ingredient oven baked summer sweet is the kind of easy dessert I reach for when I need something fast, inexpensive, and crowd-pleasing on a busy weeknight. Using dry powdered fruit gelatin mix gives it that bright, nostalgic flavor and cheerful color, while the simple baked fruit base turns jammy and bubbly in the oven. It feels a little bit like a cobbler shortcut and a little bit like a vintage potluck dessert, which is exactly why it disappears so quickly.
Serve this warm with a scoop of vanilla ice cream, a dollop of whipped topping, or a spoonful of lightly sweetened yogurt if you want to keep it simple. It also pairs nicely with grilled summer meals, backyard burgers, or a casual weekend brunch spread, since the sweet-tart fruit flavor balances richer savory dishes really well.
4-Ingredient Oven Baked Summer Sweet
Servings: 8
Ingredients
1 box (3 ounces) dry powdered fruit gelatin mix, any berry or peach flavor
1 can (20 ounces) crushed pineapple with juice
1 can (21 ounces) fruit pie filling, such as cherry, strawberry, or peach
1 box (about 15.25 ounces) yellow cake mix
Directions
1. Preheat the oven to 350°F and lightly grease a 9x13-inch baking dish.
2. Spread the crushed pineapple with its juice evenly in the bottom of the baking dish, then spoon the pie filling over the top in an even layer.
3. Sprinkle the dry powdered fruit gelatin mix evenly across the fruit layer, then scatter the dry cake mix over the top without stirring.
4. Bake for 40 to 45 minutes, until the top looks set and the fruit is bubbling around the edges. Let it rest for 10 minutes before serving.
Variations & Tips
Berry Blend: Use strawberry gelatin with cherry or mixed berry pie filling for a bright red dessert that feels especially fun for summer holidays and potlucks.
Peachy Version: Swap in peach gelatin and peach pie filling for a softer, sunny fruit flavor that is delicious with whipped cream instead of ice cream.
Make It Neater: For cleaner servings, let the dessert cool a bit longer before scooping. If you want more of a spoonable cobbler texture, serve it warm while the fruit is still nice and bubbly.
Pan Tip: Because the fruit bubbles up as it bakes, a 9x13-inch dish works best to give everything enough room. Set the baking dish on a sheet pan if you want extra protection from drips.
Meal Prep Shortcut: This is a great dessert to assemble right before dinner and bake while you eat. Leftovers can be covered and refrigerated, then reheated in the microwave for an easy next-day treat.
