Most fruit desserts feel like so much work. Multiple bowls, peeling fruit and chopping fruit, a sink full of dishes, and suddenly it’s 8:30 at night and you somehow still don’t have dessert. Well, this is not that kind of dessert.

This small-batch peach oatmeal crumble starts with two peaches, then it gets topped with a buttery oat crumble, and bakes right in a loaf pan. It’s warm, soft, crisp around the edges, and exactly the kind of thing that makes your kitchen smell like you had your life together all afternoon even if you absolutely, positively did not (and honestly, same, espeically lately, haha).

I’ve been making all kinds of loaf pan desserts recently because sometimes I want something easy, sweet, and homemade without creating enough leftovers to feed twelve people for the next four business days. And honestly? This one hits the spot.

It’s easy, cozy, and very hard to stop “just testing” (ask me how I know).

Why You’ll Love This Little Peach Crumble

This peach oatmeal crumble is simple in the best possible way. I mean the filling is basically done for you (no peeling and slicing peaches necessary), which is a huge win. The crumble comes together in one bowl and then the whole thing bakes up golden and bubbly in a loaf pan.

It tastes like something halfway between a peach crisp and a peach cobbler, except significantly easier and with way fewer dishes involved. And, the smaller size makes this feel much more reasonable, which I really love, haha.

Ingredient Notes

• Use canned peaches packed in juice, not heavy syrup.
• A small amount of cornstarch helps thicken the peach juices as the crumble bakes so the filling stays soft and scoopable instead of watery.
• Old-fashioned rolled oats give the crumble the best texture and that classic oatmeal crumble feel. Quick oats work in a pinch, but the topping will be softer and less texture-y.
• You can use light or dark brown sugar, but as usual, I feel like dark brown sugar gives the crumble a warm caramel flavor that works really well with peaches (big proponent of using dark brown sugar for pretty much everything, actually).
• Cold cubed butter works best in this loaf pan version because it helps the topping bake up crumbly instead of moist and gummy (which can happen when baking with peaches).

Step-By-Step Instructions

1. Prehet the oven to 375˚F and lightly grease an 8×4 loaf pan.
2. Place the sliced peaches to the bottom of a loaf pan and gently pat them dry with a paper towel. You don’t have to get all the moisture, but the more the better.
3. Add the brown sugar, cornstarch, cinnamon, and sea salt directly to the loaf pan. Stir gently until combined and evenly coated.
4. In a small bowl, combine the oats, flour, brown sugar, cinnamon, and sea salt.
5. Pour in the melted butter and stir until crumbly and combined.
6. Sprinkle the crumble topping evenly over the peaches in a thin layer. Don’t pack it down.
7. Bake for 35–45 minutes, or until the peaches are bubbly and tender and the topping is lightly golden.
8. Let the crumble cool for at least 15 minutes before serving unless you enjoy burning your mouth on molten peaches while insisting it was worth it. Which honestly…relatable, haha.

Recipe Tips & Notes

• Make sure your peaches are packed in juice, not heavy syrup. Syrup-packed peaches and peach pie filling both tend to make this way too sweet and way too wet, which is how you end up with oatmeal sludge instead of crumble. We’ve been through enough here already.
• Gently pat dry the peaches before adding the cornstarch, brown sugar, sea salt and cinnamon. The more moisture we can remove, the better. Peaches break down a lot when they cook.
• Fresh peaches can work too, but canned peaches packed in juice are honestly more consistent here and easier to work with (trust me, I started with fresh and had to find an easier way).
• A tiny pinch of nutmeg in the crumble topping is really good, but optional.
• Vanilla ice cream is highly recommended but also optional.
• Whipped cream is also a nice touch, if you have some or feel like making some while the crumble is baking.
• If you want to make more servings, simply double the recipe and bake it in an 8×8 pan for 45–55 minutes.

Storage Recommendations

Store peach crumble leftovers covered in the refrigerator for up to 4 days. Reheat individual portions in the microwave for 20–30 seconds. The topping softens a bit after refrigeration, but it still tastes extremely good straight from the fridge at midnight. Not that I would know anything about that.

You can freeze this peach oatmeal crumble either baked or unbaked too. Wrap it tightly and freeze for up to 3 months. If baking from frozen, add extra baking time as needed until hot and bubbly in the center.

Just know the crumble topping softens slightly after freezing and reheating, but it still tastes really good warm with ice cream.
