This peach cobbler is made for busy days when you want a homemade dessert without measuring flour, cutting butter, or preparing a separate batter. The entire dessert comes together directly in one baking dish, which means less cleanup and very little preparation.
The canned peaches provide tender fruit and the liquid needed to hydrate the cake mix as it bakes. Diet lemon-lime soda adds moisture while keeping the ingredient list short, creating a topping that is golden on the surface and soft underneath.
It is also a dependable dessert for potlucks, family dinners, and casual gatherings because one 9 x 13-inch pan makes about 12 portions. For another lighter-style sweet treat, you can also try this easy cheesecake idea when you are planning a dessert table.
Ingredients You’ll Need

You only need three main ingredients, plus optional cinnamon. Choose each one carefully because the peach liquid and the cake mix are important to the texture.
- Yellow cake mix: Use one dry box weighing approximately 15.25 ounces. Do not add eggs, oil, water, or any other ingredients listed on the cake mix package.
- Canned peaches: Use two 15-ounce cans of sliced peaches packed in light syrup or juice. Keep the peaches undrained because the liquid helps moisten the dry cake mix.
- Diet lemon-lime soda: A 12-fluid-ounce can of Sprite Zero, Diet 7UP, or a similar diet lemon-lime soda works well.
- Ground cinnamon: Add 1/2 teaspoon if you enjoy a gentle warm spice note.
Avoid draining the peaches, even if the cans seem particularly juicy. The fruit liquid works with the soda during baking, so removing it can leave dry patches in the topping.

How to Make It Step-by-Step

Step 1: Heat your oven to 350°F and lightly coat a 9 x 13-inch baking dish with nonstick cooking spray. Spraying the dish helps the bubbling peach filling release more easily when you serve the cobbler.
Step 2: Pour both cans of undrained sliced peaches evenly into the prepared dish. Spread the slices across the bottom so every serving has plenty of fruit and the peach liquid is distributed throughout the pan.
Step 3: Sprinkle the dry yellow cake mix evenly over the peaches. Resist the urge to prepare the mix according to the box directions, and do not leave thick piles of powder in one area.
Step 4: Slowly pour the 12-fluid-ounce can of diet lemon-lime soda across the surface of the cake mix. Pouring gradually gives the soda a better chance to moisten the dry ingredients, but do not stir the layers together.
Step 5: Sprinkle 1/2 teaspoon of ground cinnamon over the top if desired. The spice adds a subtle bakery-style aroma and complements the peaches without changing the basic three-ingredient method.
Step 6: Place the baking dish in the 350°F oven and bake for 45 to 50 minutes. The cobbler is ready when the top is golden brown and the peach filling is visibly bubbling around the edges and through the topping.
Step 7: Remove the dish from the oven and let it stand for about 10 minutes before serving. This short rest allows the hot juices to settle and makes portions easier to spoon.
Pro Tips for the Best Peach Cobbler

The order of the layers matters more than it may seem. Peaches go on the bottom, dry cake mix goes over the fruit, and soda goes on top, with no stirring at any point.
Stirring can create dense or gummy areas because it combines the cake mix with the fruit liquid unevenly. A slow, even pour is the best way to encourage a light cobbler-like topping.
- Use light syrup or juice: These options provide moisture without the extra sweetness of heavy syrup.
- Cover the surface: Pour the soda across as much of the cake mix as possible rather than emptying it in one spot.
- Watch the final minutes: Ovens vary, so begin checking around 45 minutes for a golden top and bubbling fruit.
- Allow the rest: Serving immediately can make the filling very loose and extremely hot.
- Portion thoughtfully: Cutting or spooning the pan into about 12 servings helps with consistent tracking.
Because cake mix brands differ, the final Weight Watchers Points value can vary. Check the nutrition information for your specific cake mix and peaches, then use the current WW calculator or app for the most accurate result.

Serving Suggestions
Serve the cobbler warm in shallow bowls so the peach juices and tender topping are easy to enjoy together. A spoonful of the bubbling fruit from the bottom should be included with every portion.
For a simple presentation, dust each serving with a very small amount of cinnamon after baking. You can also place the baking dish on a trivet and let guests serve themselves for a relaxed family-style dessert.
This recipe is sweet and satisfying on its own, so no elaborate topping is necessary. If your meal includes hearty comfort food such as cheesy tater tot casserole, a modest portion of peach cobbler provides a fruity finish.
Storage and Reheating

Cool leftover cobbler, cover the baking dish, and refrigerate it. For best texture, enjoy leftovers within a few days and keep portions chilled until you are ready to reheat them.
Reheat an individual portion in the microwave until warm, checking in short intervals so the topping does not become overly soft. You may also warm several portions in a baking dish in the oven until heated through.
The topping is at its crispest on the day it is baked, while refrigerated portions become softer as the peach juices continue to mingle with the cake layer. Even so, the leftovers remain comforting and flavorful, especially when served warm.
