If the last few weeks of summer feel like theyโ€™re slipping away, itโ€™s time to bake! These Peach Bars require a quick marinade in lemon and sugar before theyโ€™re baked in a rich buttery crust. Think peach pie meets shortbread cookie, and youโ€™re going to love them!

If you have 3 slightly underripe peaches on your counter (the ones that are kinda soft but not quite drippingly sweet and ripe), youโ€™re going to want to make these! Itโ€™s basically all of the flavors of peach pie without having to make and roll out a crust.

Weโ€™re going to quickly marinate fresh peaches in lemon and brown sugar, and then weโ€™re going to spread them between a shortbread crust. Weโ€™ll smash 80% of the shortbread dough on the bottom to make a firm crust that slices easily, and then weโ€™ll sprinkle the rest on top of the peaches.

Ingredients

Bowls of sliced fruit, flour, sugar, and butter on marble kitchen counter.
  • Peaches. We need about 3 cups of fresh sliced peaches. This is about 6 small peaches that have been peeled, pitted and sliced into about 10-12 slices each. The best way to peel peaches is to score an X in the bottom of the fruit, and dip it in boiling water for 60 seconds. Then, dunk the hot peaches in a bowl of ice water and let cool before peeling. (I use this method for my peach cobbler, too!)
  • Lemon. We need two teaspoons of fresh lemon juice to marinate and bring out the flavor of the peaches.
  • Brown Sugar. To sweeten the filling, use two tablespoons of brown sugar. If you donโ€™t have brown sugar, swap in an equal amount of granulated sugar.
  • Butter. Fourteen (yes, 14) tablespoons of unsalted butter that has been softened. This is for the top and bottom crust of the peach bars.
  • Granulated Sugar. Weโ€™ll lightly sweeten the crust with 2/3 cup of granulated sugar.
  • Flour. Measure out 1 1/3 cups of flour for the shortbread crust.
  • Cinnamon. Instead of stirring the cinnamon into the fruit, I like to stir it into the crust.
  • Cornstarch. To make the peaches in the peach bars thicken and pie-like, weโ€™ll stir two tablespoons of cornstarch into the filling before baking.

How to Make Peach Bars

First, preheat the oven to 350, and have ready an 8-inch square pan. Line it with parchment paper and clip it on two sides to secure in place.

First, marinate the peaches. Combine them in a large bowl with the brown sugar and lemon juice. Stir very well and set aside while you make the crust.

In a separate bowl, add the butter, sugar, flour and cinnamon in a bowl. Mix together very well until a dough forms.

Once the dough is formed, remove 1/2 cup of it and save it for the topping.

Press the dough evenly into the prepared pan.

Now that the peaches have marinated, stir in the cornstarch before pouring them over the crust.

Divide the reserved 1/2 cup of dough over the surface of the peaches, and bake for 40 minutes, until the fruit filling is bubbling and the edges of the crust are golden brown.

Recipe Variations

  • Flavor โ€“ In the past, I have substituted whiskey for the lemon juice with great results! If you want a โ€˜drunkenโ€™ peach pie bar, I highly recommend it!
  • Peaches โ€“ You may use frozen peaches but please defrost them fully and drain off the liquid before using. Itโ€™s even better if you lightly dry the peaches on paper towels before using, too.
  • Fruit โ€“ Can you use other fruit here? I have only made this recipe with peaches and nectarines! Peaches have low pectin levels, so you should be able to use other fruit with low pectin levels, like: raspberries, blueberries, or strawberries.

    Do you cream ingredients for the crust with a mixer or just mix with a fork or pastry cutter?

    Can you use canned peaches?
