Sweet fresh peaches are baked between layers of brown sugar and oats to form a chewy sweet crust for these Peach Oatmeal Bars.

Anytime I bake peaches into something it reminds me of my favorite peach breakfast. Peaches and cinnamon pair perfectly for your next family breakfast.

Fresh, sweet and so juicy peaches are the most amazing treat when they’re perfectly ripe. A ripe peach will have a sweet peachy smell to it and the skins will slide right off when you peel them.

What I absolutely love about these oatmeal peach bars is that they do use fresh peaches. My preference when baking is to use real fruit as much as possible.

Most peach bar recipes use a preserve or jam for the filling. That is fine but it gives the bars more of a dessert-like sometimes too sweet quality in my opinion. Real fruit-filled bars I can justify enjoying for breakfast.

Peach bars travel easily to my kids’ activities and events. Bonus, they always get rave reviews when we share them.

I love how nicely they freeze as well. I highly recommend keeping some on hand for those last-minute, “hey mom I need. . . ” requests.

Sweet and cinnamony peach bars are so easy to make. It only takes a few minutes to stir the crust together and press half of it into the pan.

Toss the peaches in sugar and spices and layer them over the crust. Sprinkle the remaining buttery crumbles over the peaches and pop it in the oven.

Peach Breakfast Bars

When baking with peaches I have noticed a difference in white peach and yellow peaches. I noticed that white peaches were not baking up the same as yellow peaches. They were losing their shape and really cooking down in the dish.

After some research, I learned that white peaches actually have a high sugar content, which explains why we love to eat them but they weren’t the best for baking. That being said stick to yellow for your baking.

As I pondered why it took me so long to learn this the answer came quite easily. Perfectly ripe peaches do not last at my house so I really have to plan ahead to have enough to bake with.

It seems like everytime a kid goes outside, they grab a peach from the basket to eat. No complaints from this mom though when they eat fruits and vegetables for snacks.

My other peach baking discovery has been a big time and frustration saver. Don’t peel the peaches. Yes, you read that correctly, leave the peels on the peaches. After baking, you won’t even notice they are there.

Now if I have to peel peaches and they aren’t quite at the perfectly ripe stage where the skins slide off, blanch them. Carefully drop the peaches into a pot of boiling water for 30 seconds. Then plunge them into an ice bath.

The skins literally slide off. You won’t even need a knife.

Yes! You can use frozen peaches for these oatmeal bars. I would suggest a couple of things. First, let the peaches thaw. Second, be sure to drain off excess liquid. Lastly consider adding an extra tablespoon of corn starch.

Frozen peaches tend to have excess juices when they thaw so discarding that liquid and adding a tad more corn starch will ensure your oatmeal bars aren’t soggy.

Peach Bars Recipe

  1. Preheat oven to 400°F. Grease a 9×13 pan with butter and set aside. Combine the peaches with the white sugar, cinnamon, salt, and cornstarch in a large mixing bowl.
  2. Stir to coat and add the lemon juice. Stir again and then let the peaches rest while preparing the crust.
  3. In a separate mixing bowl, combine the flour, oats, and brown sugar. Add the melted butter. Stir to combine.
  4. Press half of this mixture into a buttered 9×13 pan. Pour the fruit over the bottom crust and then sprinkle the rest of the dry mixture on top.
  5. Bake for 34-36 minutes, until the crust turns golden brown. Let cool completely and slice into bars.

Recipes with peaches are a seasonal favorite, and are always high on my list. Crisps, crunches, coffee cake, pound cake, or cobbler we love the sweet freshness of peaches in countless desserts.

Southern Peach Cobbler is filled with fresh juicy peaches and then topped with a generous cinnamon sugar crust that manages to be both buttery and flaky while never becoming soggy, even after a day or two in the refrigerator.

You need just three ingredients to make this homemade peach sauce. The deliciousness begins with ripe, juicy, peaches. When the peaches grow fragrant and soften, that’s the signal that it is time to start making our favorite peach recipes.

I don’t put up many canned items. However, this wonderfully spiced peach jam with just a hint of cinnamon has been a staple in our home for about 15 years.

Peaches aren’t just for baking. They bring sweetness to summer salads like this Peach Caprese Salad. And next time you’re grilling, try this Grilled Peach Salad for a memorable dinner side.

      Absolutely, Virginia!

  4. Elaine says:

    I’m fixing to make this right now–I love any fruit dessert and this looks yummy and easy. I’ve got a couple quarts of canned peaches left, and also some leftover old fashioned oats that I toasted for granola–do you think toasted oats would work for this recipe?

    1. Mary Younkin says:

      Those should work fine, Elaine.

  5. Nicole Posada says:

    I put peaches on the list to make these, and my husband came home with canned peaches- ugh- Can I use these? Or will it be Terrible?5 stars

    1. Mary Younkin says:

      Thank you so much, Jamie! I am delighted you enjoy the recipes on this site.

  7. Daniela says:

    All I have is quick oats. Do you think it would work

    1. Mary Younkin says:

      Hi, Daniela! I’m not sure how well the bars would turn out. I think they’d hold together, but I can’t make any promises about their texture. If you decide to make these bars with quick oats, please let me know how they turn out.

  8. RL says:

    These were delicious! Not too sweet. I browned the butter for fun. Love not having to cut in cold butter to the crust mix. I will make this again with different fruits!5 stars

    1. Mary Younkin says:

      Happy to hear that you’re loving the peach oatmeal bars. Enjoy, and happy baking!

  9. Deb B says:

    By “bar” I thought that these would be more firm. I was looking for more of a granola bar so that’s probably my mistake. I’m gonna put them back in the oven at a low temp to see if I can dry it out a bit. They are very moist and pretty soft. Also very sweet. I would cut back on the sugar. But they are yummy!3 stars

    1. Mary Younkin says:

      Glad to hear that you enjoyed the oatmeal bars, Deb! They’re definitely supposed to be a soft bar, not crisp like a granola bar. Happy baking!

  10. Sue says:

    Amazing. They are so good and easy to make. I used frozen peaches and cut them all thinner before I made the recipe.

    Question on how to store them? I need them for a party tomorrow.5 stars

    1. Mary Younkin says:

      If you’re house is on the cooler side, they should be fine at room temperature. Otherwise, I’d just pop them in the fridge overnight and allow them to warm to room temp before serving.

  11. Francine Ephraim says:

    Do you think I could slice these and freeze them? If so, do you have suggestions for how to freeze and how to defrost and serve?

    1. Mary Younkin says:

      Absolutely! I typically thaw in the fridge or on the counter. They might be a little more moist after freezing, but we still enjoy them.

  12. Cheryl Chiasson says:

    I’ve made this recipe several times. It’s a hit every time! I use frozen peaches that I freeze myself each summer. I add an extra tablespoon of corn starch due to frozen peaches.

    1. Mary Younkin says:

      I’m so glad you like the peach bars, Cheryl!
