Ingredients You’ll Need
This recipe uses pantry staples to create something truly special. Here’s what you’ll need to gather.

For the Peach Filling
- Peaches: About 6 medium ripe peaches, peeled and sliced. You can also use canned or frozen.
- Granulated Sugar: To sweeten the filling. Adjust based on the sweetness of your peaches.
- Cornstarch: This helps thicken the peach juices into a lovely syrup.
- Lemon Juice: A little acidity brightens the flavor of the peaches and balances the sweetness.
- Cinnamon: A pinch of warm spice complements the fruit perfectly.
For the Crispy Oatmeal Topping
- All-Purpose Flour: Provides the structure for our crumble topping.
- Old-Fashioned Rolled Oats: The star ingredient! They provide a wonderful chewy texture and nutty flavor. Do not use instant oats.
- Brown Sugar: Adds moisture and a rich, caramel-like sweetness. Light or dark brown sugar works well.
- Granulated Sugar: For extra sweetness and crispness.
- Cold Unsalted Butter: The key to a flaky, crumbly topping is using cold, cubed butter.
- Cinnamon & Nutmeg: These warm spices make the topping extra cozy and delicious.
- Salt: A pinch of salt enhances all the other flavors.
How to Make Peach Cobbler with Oatmeal Topping (Step-by-Step)
Making this dessert is as easy as 1-2-3! Just prepare the filling, mix the topping, and bake to bubbly perfection.
1. Prepare the Peach Filling
First, preheat your oven to 375°F (190°C). In a large bowl, gently toss the sliced peaches with the granulated sugar, cornstarch, lemon juice, and cinnamon. Make sure every slice is evenly coated. Pour this mixture into a 9×9 inch baking dish (or a similar 2-quart dish) and spread it out in an even layer.
2. Make the Crispy Oatmeal Topping
In a separate medium bowl, whisk together the all-purpose flour, old-fashioned rolled oats, brown sugar, granulated sugar, cinnamon, nutmeg, and salt. Add the cold, cubed butter to the dry ingredients. Using a pastry blender or your fingertips, cut the butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces remaining. Don’t overmix!
3. Assemble and Bake
Evenly sprinkle the oatmeal topping over the peach filling in the baking dish, covering it completely. Place the dish on a baking sheet to catch any potential drips. Bake for 35-45 minutes, or until the fruit filling is bubbly and thick, and the topping is a deep golden brown. Let the cobbler cool on a wire rack for at least 15-20 minutes before serving. This allows the filling to set up properly.

Pro Tips for the Best Cobbler
- Use Cold Butter: For the crispiest, most delicious crumble topping, your butter must be cold. This creates little pockets of steam as it melts in the oven, resulting in a lighter, flakier texture.
- Don’t Overmix the Topping: Mix the topping until it just comes together into crumbs. Overworking the dough can develop the gluten in the flour, making the topping tough instead of tender and crispy.
- Let It Rest: Letting the cobbler cool for at least 15 minutes is crucial. It gives the jammy fruit filling time to thicken, making it much easier to serve.
- Bake on a Sheet Pan: Placing your baking dish on a foil-lined baking sheet is a smart move. The peach filling will bubble up, and this simple step makes cleanup a breeze.
Fresh, Canned, or Frozen Peaches?
You can absolutely make a fantastic peach cobbler with oatmeal topping no matter what kind of peaches you have. Here’s how to adjust the recipe for each type:
| Peach Type | Instructions |
|---|---|
| Fresh Peaches | This is the classic choice! Use ripe, fragrant peaches. Follow the recipe as written. No need to peel them if you prefer the texture of the skin. |
| Frozen Peaches | Do not thaw! Using them frozen prevents them from getting mushy. You may need to add an extra 5-10 minutes to the baking time. |
| Canned Peaches | Drain them very well. If they are packed in syrup, you may want to reduce the amount of sugar in the filling by a few tablespoons to avoid it being overly sweet. |
Variations and Substitutions
Feel free to customize this recipe to your liking! Here are a few ideas:
- Add Nuts: For extra crunch, add 1/2 cup of chopped pecans or walnuts to the oatmeal topping mixture.
- Spice It Up: Add a pinch of cardamom or ginger to the filling for a different warm spice profile.
- Make It Gluten-Free: You can easily make a gluten-free peach cobbler by substituting a 1-to-1 gluten-free baking flour blend for the all-purpose flour in the topping. Ensure your oats are certified gluten-free as well.
- Other Fruits: This oatmeal topping is fantastic with other fruits like apples, berries, or a mix of stone fruits.
Storing and Reheating
Leftover peach cobbler is a wonderful treat! You can store it covered at room temperature for up to 2 days or in the refrigerator for up to 5 days. To reheat, place it in a 350°F (175°C) oven for 10-15 minutes, or until warmed through. This helps re-crisp the topping beautifully.
