I must admit, when fresh peaches hit our area, I seem to be making everything peaches! This summer I’ve been making peach ice cream, peach cobbler and now these peach bars.  

What is a Peach Crumb Bar?

These peach bars are made with an oatmeal crust topped with a delicious peach filling and a crumb topping. The filling really is a combination between peach cobbler and peach pie. You just can’t go wrong there, can you? The topping is the same as the crust, but it’s crumbled over the peach filling. The whole pan is baked until all that peach filling is nice and bubbly and the topping is browned.

You could eat this straight out of the oven, but the bars won’t hold together. If you want to cut these into bars, you’ll need to have some patience and let the bars fully cool. 

Can I make these ahead of time?

These bars are best eaten the same day they are baked. The bars become too moist if made too far ahead of time. 

How do I make peach crumb bars?

    1. Mix flour, oats, cinnamon, brown sugar, salt and baking powder together
    2. Add melted butter a glass bowl with brown sugar and melted butter poured over the top.
    3. Mix with a spoon until well combine Oats mixed together in a bowl.
    4. Pour half of the oat mixture into a greased baking dish. 
    5. Press mixture down into pan Oatmeal crust in a baking dish.
    6. Bake for for 15 minutes
    7. Peel and chop peaches. Combine peaches, corn starch, brown sugar and cinnamon in a bowl Chopped peaches in a bowl with a pink spatula.
    8. Spoon peaches onto crust. Do not use all the juices from the peaches. I used a slotted spoon and got some of the juice, but left the rest behind. Peaches on an oatmeal crust.
    9. Crumble remaining oat mixture onto peaches Crumbling oat mixture onto chopped peaches.
    10. Bake for 45-50 minutes
    11. Allow bars to fully cool before slicing and serving Peach bar topped with an oatmeal topping.

Do I use fresh or frozen peaches?

You can use either fresh or frozen peaches in this recipe. I’ve been making these during fresh peach season but it’s just as delicious when only frozen peaches are available. To use frozen peaches, allow peaches to thaw first and then follow recipe directions. 

Tips for making Peach Bars

  • Use old fashioned oats (also called rolled oats) for this recipe. These oats are hearty and will hold their shape.
  • Peel your peaches. Some peaches can be peeled raw by just using a paring knife. Others will need to be blanched first and then peeled. Try paring first and then move to blanching if needed.
  • This recipe calls for 5 cups of chopped peaches which is approximately 5 large peaches. If you end up with a bit more than 5 cups, just add them in. The filling doesn’t require precise measurements.
  • Allow bars to fully cool before cutting and removing from pan.
  • Serve at room temperature or chilled, if desired.

    I love a good oat crumble! The flavor is amazing, and it reminds me of Fall thanks to the oats and cinnamon. You know me and peaches, so I’d love to polish off a plate of these bars!
