Peach Cobbler with Cake Mix

If you want a dessert that tastes like you spent all afternoon in the kitchen, but really only asked you to open a cake mix and slice a little fruit, this is your cobbler. It bakes up with jammy peaches underneath and a buttery, crisp, cake-like top. It is the kind of warm, scoopable magic that makes vanilla ice cream mandatory.

I make this when peaches are overflowing in summer, and also when it is rainy and I need a little sunshine in February. Fresh, frozen, or canned peaches all work. I will show you how to tweak each one so you get that perfect gooey fruit and crunchy-buttery top every time.

Why this cobbler works

• Minimal prep: No homemade biscuit dough, no rolling, no fuss.
• Big payoff: The butter melts through the cake mix, creating crisp, golden pockets.
• Flexible fruit: Fresh, frozen, or canned peaches can all become cobbler.
• Weeknight-friendly: The oven does the heavy lifting while you clean up and set the table.

Ingredients

You only need a handful of grocery store staples. Exact amounts are below, but first, here is what matters most.

What you need

• Peaches: Fresh, frozen, or canned.
• Yellow cake mix: Classic flavor and browning. Butter cake mix works too.
• Butter: This is the secret to that crisp topping. Use real butter, not margarine.
• Sugar: Adjust based on how sweet your peaches are.
• Lemon juice: Brightens the filling and keeps it from tasting flat.
• Cinnamon and salt: Small additions that make the peaches taste extra peachy.
• Cornstarch (optional): Helpful for very juicy peaches and extra-drippy frozen fruit.

Ingredient list (9x13-inch pan)

• 6 to 7 cups sliced peaches (about 2 1/2 to 3 pounds / 1.1 to 1.4 kg), or 2 (29-ounce) cans sliced peaches, drained, or 6 to 7 cups frozen peaches
• 1/3 to 1/2 cup granulated sugar (start with 1/3 cup and taste)
• 1 tablespoon lemon juice
• 1 teaspoon vanilla extract (optional but lovely)
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon fine salt
• 1 to 2 tablespoons cornstarch (optional, as needed)
• 1 box (15.25-ounce) yellow cake mix
• 3/4 cup (1 1/2 sticks) unsalted butter, melted and warm (not scorching hot)

Note on canned peaches: Peaches packed in juice, light syrup, and heavy syrup can all work here. Drain them well. No rinsing needed. If yours are in heavy syrup or taste very sweet, start with 0 to 2 tablespoons sugar and taste before adding more. Also, using two large cans makes a very fruit-forward cobbler, which is exactly how I like it.

How to make peach cobbler with cake mix

I promise this is simple. The key is layering and getting the butter evenly distributed so you do not end up with dry powdery patches.

Step 1: Heat the oven

Preheat to 350°F. Lightly butter or spray a 9x13-inch baking dish.

Step 2: Make the peach layer

In a large bowl, toss peaches with sugar, lemon juice, vanilla (if using), cinnamon, salt, and cornstarch (if using). Pour into the prepared baking dish and spread into an even layer.

Little tip from my teacher heart: Taste one peach slice after tossing. If it does not taste like you want to eat it right now, add another tablespoon or two of sugar.

Step 3: Add the cake mix

Sprinkle the dry cake mix evenly over the peaches. Do not stir. Gently shake the dish so the mix settles into an even blanket.

Step 4: Add the butter

Drizzle the melted butter slowly and as evenly as you can over the entire surface. I like to pour in thin lines across the dish, then repeat the other direction. (If drizzling is tricky, spoon it over in small puddles and keep going until you have good coverage.)

If you see a few small dry spots, that is okay. They usually disappear as it bakes. If you still have more than a few spoonfuls of dry mix showing, add 2 to 4 tablespoons more melted butter, focusing on those areas. You can also gently tap or very lightly press the dry mix into the butter with the back of a spoon, just enough to help it moisten. Still no stirring.

Step 5: Bake

Bake for 45 to 55 minutes, until the top is deeply golden and the peach filling is bubbling around the edges. Let it cool for 15 minutes before serving so the filling thickens slightly. Serve warm.

Fresh vs frozen vs canned peaches

All three work. Here is how I adjust so the filling is the right texture.

Fresh peaches

• Best for: Peak summer flavor.
• Tip: If they are extra juicy, use 1 tablespoon cornstarch.
• Peeling: Optional. I usually leave skins on for weeknights, but peel if you want a softer, more classic filling.

Frozen peaches

• Best for: Year-round cobbler.
• Tip: Use them straight from frozen. No need to thaw. Add 1 to 2 tablespoons cornstarch, depending on how much liquid your brand tends to release.
• Bake time: It may need 5 to 10 extra minutes.

Canned peaches

• Best for: Pantry-friendly convenience.
• Tip: Drain well. If packed in heavy syrup, start with 0 to 2 tablespoons sugar, then taste.

Tips for a crisp topping

• Spread the mix evenly: Uneven cake mix means uneven browning.
• Butter coverage matters: Drizzle slowly and cover the surface. Dry patches mean not enough butter in that spot.
• Go for deep golden: Pale topping tastes floury. Golden topping tastes like caramelized butter.
• Rest before scooping: 15 minutes helps the juices thicken so it is less soupy.

If you are torn between “is it done?” and “maybe five more minutes,” choose five more minutes. Cobbler likes confidence.

Easy variations

Spiced peach cobbler

Add 1/4 teaspoon nutmeg and a pinch of ground ginger to the peaches.

Brown sugar peach cobbler

Swap half the granulated sugar for light brown sugar for a deeper, caramel note.

Peach and berry cobbler

Replace 1 to 2 cups of peaches with blueberries or blackberries. Keep the total fruit amount about the same.

Extra crunchy top

Sprinkle 1/2 cup chopped pecans or sliced almonds over the buttered cake mix before baking.

What to serve with peach cobbler

I will never tell you not to eat it straight from the pan, but if you want the full experience:

• Vanilla ice cream: The classic, and for good reason.
• Whipped cream: Light and pretty on warm cobbler.
• Greek yogurt: My “breakfast cobbler” move, especially with a drizzle of honey.

Make-ahead, storage, and reheating

Make-ahead

This is best baked the day you serve it, but you can prep the fruit mixture up to 1 day ahead and refrigerate it. Sprinkle on cake mix and butter right before baking.

Storing leftovers

Cover and refrigerate for up to 4 days.

Reheating

• Oven (best for crisp top): 350°F for 12 to 18 minutes.
• Microwave (fast): 30 to 60 seconds per serving. The topping will soften, but it is still delicious.

Freezing

You can freeze baked cobbler, but the topping softens after thawing. If freezing, cool completely, wrap well, and freeze up to 2 months. Rewarm in the oven to help re-crisp the top.

Troubleshooting

Why is my topping still powdery?

Usually the butter did not reach those areas. Next time, drizzle more evenly, or add a few extra tablespoons of melted butter if you see dry patches before baking. You can also lightly press the dry mix into the butter with the back of a spoon, gently, no stirring.

Why is my cobbler runny?

It may need more bake time, more rest time, or a little thickener. Very juicy peaches (and some frozen peaches) benefit from 1 to 2 tablespoons cornstarch. Also make sure the filling is bubbling, since bubbling means it reached a thickening temperature.

Can I use a different cake mix?

Yes. White cake mix is a little lighter. Spice cake mix is cozy and fall-ish. “Pudding in the mix” styles can bake up a bit softer on top, but they still work.

Do I stir the cake mix into the peaches?

Nope. The magic is in the layers. Fruit on the bottom, dry mix on top, butter over everything.

Recipe: Peach Cobbler with Cake Mix

Yield: 10 to 12 servings
Time: 10 minutes prep, 45 to 55 minutes bake

Ingredients

• 6 to 7 cups sliced peaches (about 2 1/2 to 3 pounds / 1.1 to 1.4 kg), or 2 (29-ounce) cans sliced peaches, drained, or 6 to 7 cups frozen peaches
• 1/3 to 1/2 cup granulated sugar (or 0 to 2 tablespoons if using very sweet canned peaches)
• 1 tablespoon lemon juice
• 1 teaspoon vanilla extract (optional)
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon fine salt
• 1 to 2 tablespoons cornstarch (optional)
• 1 box (15.25-ounce) yellow cake mix
• 3/4 cup unsalted butter, melted and warm

Instructions

1. Preheat oven to 350°F. Grease a 9x13-inch baking dish.
2. Toss peaches with sugar, lemon juice, vanilla (if using), cinnamon, salt, and cornstarch (if using). Pour into the baking dish.
3. Sprinkle dry cake mix evenly over the peaches. Do not stir.
4. Drizzle melted butter evenly over the cake mix.
5. Bake 45 to 55 minutes, until deeply golden and bubbling at the edges.
6. Cool 15 minutes, then serve warm with ice cream or whipped cream.

If you make this, do yourself a favor and bake it until it is truly golden. That buttery crunch on top is the whole point.

FAQ

Can I make this in a 9x9 pan?

Yes. Halve the ingredients and start checking around 35 to 40 minutes. You still want bubbling edges and a golden top.

Should I cover cobbler while baking?

No. Leaving it uncovered helps the topping brown and crisp.

What if my peaches are not sweet?

Add more sugar. Peaches vary wildly. Start with 1/3 cup, taste, and adjust until the fruit tastes pleasantly sweet before it goes into the oven.
