If you want the comfort of peach cobbler without the whole measuring cups everywhere situation, this is the one. We lean on boxed cake mix for the topping, but we still treat the peaches like they deserve a little respect: a pinch of salt, a bright squeeze of lemon, and just enough thickener so the filling turns glossy and jammy instead of watery.
This is my Portland summer staple when peaches are perfect, and my winter “I need a warm dessert tonight” move with frozen or canned peaches. Serve it warm with ice cream and you have that restaurant-level hot-cold magic with weeknight effort.
If you make this, taste a peach before you add sugar. That one tiny step is how you get a cobbler that tastes like fruit first, dessert second. And if you find yourself with peaches that are getting a little too soft on the counter, this is one of my favorite ways to save them.
Why this recipe works
- Balanced sweetness: Cake mix brings sugar, so we keep the filling lightly sweet and add lemon for lift.
- Real cobbler texture: Butter + dry cake mix creates crisp, buttery crumbles and tender pockets, not a spongy sheet cake.
- No soupy bottom: A quick toss with cornstarch (or flour) thickens the peach juices as they bubble.
- Flexible fruit: Fresh, frozen, or canned all work with small tweaks.
Ingredient notes
Peaches: fresh vs frozen vs canned
Fresh peaches
Best flavor and texture when they are in season. Yellow peaches usually taste more classic “peach cobbler” to me, while white peaches can be sweeter and a little more floral, so taste and adjust sugar. If your peaches are very juicy, keep the full 2 tablespoons cornstarch. If they are super firm, slice a little thinner so they soften fully.
Frozen peaches
No need to thaw. Toss frozen slices with the filling ingredients and keep mixing until the cornstarch is evenly distributed, since it can cling to cold fruit. Expect to add 5 to 15 minutes of bake time depending on pan depth and how frozen your fruit is. If you do thaw them, drain off excess liquid before mixing so the cobbler does not turn soupy.
Canned peaches
Drain well, especially if packed in syrup. Most stores carry 15-ounce cans more reliably than the large 29-ounce size, so either works. I usually cut the added sugar down to 1/4 cup for syrup-packed peaches, then rely on lemon and salt to keep it from tasting one-note sweet.
Cake mix
Yellow cake mix gives the most “buttery bakery” flavor. White cake mix is a little lighter.
Sweetener
Use 1/4 cup sugar if your peaches are very sweet, or if using peaches canned in syrup.
Thickener
Cornstarch thickens the peach juices as they bubble. All-purpose flour also works (use 3 tablespoons).
Butter
If using salted butter, use a slightly smaller pinch of kosher salt.
Equipment you will need
- Deep 9x13-inch baking dish (at least 2 inches deep) or a deep 10-inch skillet
- Baking sheet (optional, for very juicy peaches or frozen fruit if you are worried about bubbles)
- Large mixing bowl
- Liquid measuring cup with a spout or a spoon (for drizzling butter)
- Foil (for tenting if the top browns too quickly)
Pro tips
How to get a crisp top
- Do not stir the cake mix into the fruit. You want a separate topping layer that bakes up crisp in butter.
- Drizzle butter evenly. If you dump it in one spot, you get a greasy patch and dry powder elsewhere.
- Bake until bubbling. Bubbles at the edges mean the filling thickener activated. If it is not bubbling, it will taste thinner.
- Cool before serving. Cooling time is not optional if you want a set, glossy filling.
Tip: Taste a peach before you add sugar, then adjust.
Substitutes that work
- Peaches: Use fresh, frozen (no need to thaw), or canned peaches (well drained).
- Thickener: Use 2 tablespoons cornstarch or 3 tablespoons all-purpose flour.
- Cake mix: Yellow cake mix is classic; white cake mix also works.
- Peach pie filling: You can use it, but it is already thick and sweet. Skip the sugar and cornstarch, add lemon juice and salt, and taste the filling before you commit.
Variations
Brown butter peach cobbler
Brown the butter before drizzling for a toasty, nutty finish. Let it cool 5 minutes so it does not instantly soak into one spot.
Spiced peach cobbler
Add 1/4 teaspoon ground ginger and a tiny pinch of nutmeg with the cinnamon. It reads like “holiday peaches” in the best way.
Berry peach cobbler
Swap 2 cups of the peaches for blueberries or blackberries. Keep the cornstarch the same.
Gluten-free
Use a gluten-free yellow cake mix and cornstarch. Everything else stays the same. Just check your mix size, some are slightly smaller.
Serving ideas
- Vanilla ice cream (classic for a reason)
- Greek yogurt + honey for a breakfasty situation
- Lightly sweetened whipped cream with a pinch of salt
- A splash of cold heavy cream right over the hot cobbler
Storage and reheating
- Make ahead: You can assemble up to the cake mix layer, cover, and refrigerate for up to 12 hours. Add butter right before baking so the topping stays craggy and crisp.
- Store: Cover and refrigerate leftovers for up to 4 days.
- Reheat: Warm in a 350°F oven for 12 to 18 minutes to re-crisp the top. Microwave works for speed, but the topping softens.
- Freeze: Freeze baked cobbler tightly wrapped for up to 2 months. Thaw overnight in the fridge, then reheat in the oven.
Common mistakes
My cobbler is watery
Most often: not enough bake time (it must bubble) or not enough cooling time. If you already served it and it is thin, rewarm the pan at 350°F for 10 minutes, then cool again for 20 minutes.
I have dry powdery spots on top
Totally normal in small patches. If you want a more even finish, drizzle 1 to 2 extra tablespoons melted butter over the driest areas halfway through baking.
The top is browning too fast
Loosely tent with foil. Keep baking until the filling bubbles at the edges.
FAQ
Do I need to peel the peaches?
No. Peach skins soften as they bake. If skins bother you, peel them, but I usually leave them on to save time and reduce waste.
Can I use peach pie filling?
You can, but it is already thick and sweet. Skip the sugar and cornstarch, add lemon juice and salt, and taste the filling before you commit.
Which cake mix is best?
Yellow cake mix gives the most “buttery bakery” flavor. White cake mix is a little lighter. Spice cake mix is fun with peaches, but it can overpower delicate fruit, so use it when your peaches are not peak-season perfect.
Peach Cobbler with Cake Mix
A comfort-food peach cobbler made easy with boxed cake mix, but with a fruit-forward filling that bakes up glossy and jammy (not watery). Works with fresh, frozen, or canned peaches, and finishes with a crisp, buttery, craggy topping.

Ingredients
- Peaches (choose one):
- Fresh: 2 1/2 pounds peaches, sliced (about 6 to 7 cups, usually 7 to 9 medium depending on size)
- Frozen: 2 1/2 pounds frozen sliced peaches (no need to thaw)
- Canned: 4 (15-ounce) cans sliced peaches, well drained (or 2 large 29-ounce cans)
- 1/3 cup granulated sugar (use 1/4 cup if your peaches are very sweet, or if using peaches canned in syrup)
- 2 tablespoons brown sugar (optional, for a caramel note)
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/2 teaspoon kosher salt (use a slightly smaller pinch if using salted butter)
- 2 tablespoons cornstarch (or 3 tablespoons all-purpose flour)
- 1 (15.25-ounce) box yellow cake mix (white also works)
- 10 tablespoons unsalted butter (1 stick + 2 tablespoons), melted and cooled slightly
- Optional but great: 1/3 cup sliced almonds or chopped pecans
Instructions
- Heat the oven. Preheat to 350°F. Butter a deep 9x13-inch baking dish (at least 2 inches deep) or a deep 10-inch skillet. Place the dish on a baking sheet if you are using very juicy peaches or frozen fruit and you are worried about bubbles.
- Mix the peach filling. In a large bowl, toss peaches with granulated sugar, brown sugar (if using), lemon juice, vanilla, cinnamon, salt, and cornstarch until the cornstarch is fully dissolved and evenly coats the fruit. If using frozen peaches, keep tossing and break up any cornstarch pockets clinging to cold fruit.
- Build the base. Scrape the peaches and all their juices into your baking dish and spread into an even layer.
- Add the cake mix. Sprinkle the dry cake mix evenly over the peaches. Do not stir. If you want extra crunch, scatter nuts over the top.
- Butter it like you mean it. Drizzle melted butter evenly over the cake mix. A liquid measuring cup with a spout helps, or drizzle with a spoon in thin ribbons. If you spot dry areas, dab them with a little more butter so the topping bakes crisp, not dusty.
- Bake. Bake 40 to 55 minutes, until the top is deeply golden and the peach juices are bubbling around the edges. If the top is browning too quickly, loosely tent with foil for the last 10 minutes.
- Cool (this is the hard part). Let cool 15 to 20 minutes before serving so the filling thickens into that spoonable, glossy sauce.
Notes
- Frozen peaches: No need to thaw. Expect to add 5 to 15 minutes of bake time depending on pan depth and how frozen your fruit is. If you do thaw them, drain off excess liquid before mixing so the cobbler does not turn soupy.
- Canned peaches: Drain well, especially if packed in syrup. Consider using 1/4 cup sugar for syrup-packed peaches, then rely on lemon and salt to keep it from tasting one-note sweet.
- For a crisp, craggy topping: Do not stir the cake mix into the fruit, drizzle butter evenly, and bake until the edges bubble. Cool 15 to 20 minutes before serving.
