Peach Bars Recipe with Fresh Peaches and Almond Crumble

This post may contain affiliate links. Please read our disclosure policy.

Peach Bars start with a pressed shortbread crust, a thick layer of fresh peaches, and an almond crumble on top. My secret is par-baking the crust for ten minutes before the peaches go on, which keeps the bottom from turning soggy under all that juice. The crumble uses almond flour and finely chopped almonds instead of oats (y’all know I don’t like oats in streusel!), so it bakes up sandy and crisp rather than chewy. They do need time in the refrigerator before slicing, so don’t count on cutting into them straight out of the oven.

So this recipe is a blend of several of my favorite things. First of all, I could eat shortbread until the cows come home, so I made these peach bars with a shortbread crust. And then peaches are my favorite summer fruit, if you don’t count blackberries… and watermelon… so fresh peaches are a must in this luscious filling.

And then the topping really brings it home. Y’all know I hate oats in any kind of baked dessert topping (my famous Apple Crisp Without Oats attests to this), so I wanted a crispy topping but with no oats. I used almond flour and finely chopped almonds to carry more of the almond flavor, and let me tell you — these little bars are delightful and out of this world delicious!

Testing results for peach bars

Peach ripeness. Peaches that were ripe but still firm held their shape and the filling set. Over-ripe peaches emitted too much liquid and the bars never cooked through properly.
Chilling before slicing. Cutting at room temperature gave ragged edges and a filling that slumped. An hour in the refrigerator firmed things up enough for clean squares.
Loose covering beat airtight. These bars are wet by nature, and sealing them up trapped that moisture against the topping. Loosely covered in the refrigerator, the crumble stayed crisp. One thing to note: these bars are best consumed the day you make them. They will keep in the fridge, but the topping will start to get soggy.

Ingredient notes

Here are a few things to know about the ingredients in this recipe.

➡️➡️➡️ The full ingredient amounts and instructions are listed below on the printable recipe card. Scroll below the recipe card for frequently asked questions and tips for success.

Fresh peaches. You need five cups of peeled and diced fresh peaches, which is roughly six to eight medium peaches depending on size. Look for fruit that smells like a peach and gives just slightly when you press near the stem.

Cold unsalted butter. Sixteen tablespoons total, split between the crust and the crumble, and it needs to be cold in both. Cut it into cubes straight from the refrigerator. If it softens while you’re measuring everything else, put it back in for a few minutes.

Almond flour. Half a cup goes into the crumble alongside the all-purpose flour. Almond flour has no gluten to develop, so it helps to keep the topping sandy and crisp instead of letting it bake into a solid sheet.

Almond extract. A total of three-quarters of a teaspoon across the filling and the crumble.

Flour and cornstarch in the filling. The flour absorbs liquid, and the cornstarch sets it into something sliceable once the bars cool.

Lemon juice. Two tablespoons, to help prevent the diced fruit from browning.

Finely chopped almonds. A quarter cup stirred into the crumble at the very end. Chop them fine so they toast evenly under the oven’s heat.

How to make peach crumble bars

Cut cold butter into the crust ingredients, then bind the mixture with egg and vanilla. It will look dry, which is fine. It won’t be dry after it bakes.
Press the crust into a parchment-lined pan and par-bake it until it’s set. This keeps the bottom from getting soggy once you add the filling.
Toss the diced peaches with lemon juice, sugar, the thickeners, cinnamon, and both extracts until every piece is coated.
Work cold butter into the almond crumble mixture with fingers or a fork until large crumbs form, then stir in the chopped almonds.
Spread the filling over the par-baked crust, scatter the crumble on top, and bake until the topping is golden and the edges bubble. Cool completely, then refrigerate before slicing.

Why fresh peaches work best

Peach bars with fresh peaches come down to one question: how much water is in the pan. Five cups of diced fruit carries a lot of liquid, and the quarter cup of flour and two tablespoons of cornstarch in the filling are measured to offset some of that liquid. Anything wetter going in means a filling that stays loose under the crumble no matter how long you bake it.

That’s why ripeness matters so much here. Let’s get scientific: A peach that’s ripe but still firm has intact cell walls, and it softens in the oven while holding its shape. An overripe peach has already started breaking down before it ever gets diced, so those walls collapse under heat and saturate the crust. The bars won’t cook through, and you’ll just end up with an over-baked, liquidy (that’s a word, right?) big ole mess.

Canned peaches are out for the same reason. They’re packed in syrup or juice, and the processing has already softened them past the point where they’ll hold up. You’d be adding liquid and subtracting texture at the same time.

I haven’t tested these with frozen peaches, but I really don’t think they would work well either. Frozen fruit releases a lot of water as it thaws. Just get yourself some fresh peaches and call it good.

Peach crumb bar variations

Leave the peel on. Peeling five cups of peaches takes a while, and the skins give you more color and a little more texture in the finished bar.
Cut them small. The pan gives you twelve generous bars at about three inches square, or twenty-four smaller ones.
Pecans instead of almonds. Swapping the chopped almonds for finely chopped pecans is an easy change if that’s what’s in the pantry. I haven’t tested this but I think it would work just fine.
Vanilla only. If almond flavor isn’t your thing, leaving it out of both the filling and the crumble gives you a straight peach bar. The almond flour stays either way, since it’s doing structural work in the topping and it doesn’t lend much almond flavor.

P.S. If you bought peaches by the half bushel and you’re running out of dessert ideas, my Peach Barbecue Sauce puts them to work on the savory side of supper.

Make-ahead and storage

Make ahead. These peach bars do need to chill for at least an hour before slicing. You can make them the day you need them and let them rest in the fridge until you’re ready. I don’t like to make them more than a day in advance because the crust and topping start to get soft.

For the best make-ahead option, I get everything ready separately and then put it together and bake the day of. So, make up the crust but don’t bake it. Just stick the pan in the fridge. Make the filling and store in the fridge. Mix up the almond crumble topping and store that in the fridge. Then bake when you’re ready.

Storage. Keep them in the refrigerator, loosely covered rather than sealed in an airtight container. With five cups of fresh peaches in the pan, these bars hold a lot of moisture, and trapping it turns the crumble soft. A little air circulation helps keep the topping somewhat crisp.

Freezing. You can freeze leftover peach bars for up to two months. Thaw them overnight in the refrigerator rather than on the counter, which keeps condensation off the topping. I don’t think the texture is as good as when you first make them, but they still taste delicious!

What to serve with peach bars

These peach bars are so delicious just as they are, but if you want to fancy them up a little you could add a dollop of Homemade Whipped Cream alongside. And of course, vanilla ice cream is good with pretty much everything.

Questions and tips

Storage

Keep them in the refrigerator, loosely covered rather than sealed in an airtight container. With five cups of fresh peaches in the pan, these bars hold a lot of moisture, and trapping it turns the crumble soft. A little air circulation is what keeps the topping crisp.

Can I make these peach bars in a smaller pan?

The recipe is built for a 9×13-inch dish. Moving it to a 9×9 or 8×8 would give you a much thicker bar with a deeper layer of fruit, which changes both the bake time and how well the filling sets. I haven’t tested it that way, but I know that you would need to adjust the baking time, and I worry that the bars won’t set and will have a tough time cooking through.

Do I really need the parchment paper?

Yes, either parchment paper or tin foil. The overhang lets you lift the entire slab out of the pan once it’s chilled and cut it on a board, which is how you get straight edges.

Can I leave out the almond flour?

Almond flour is contributing texture to the topping. It has no gluten, so it keeps the crumble sandy and separate instead of letting it bake into one solid layer. Replacing it with all-purpose flour will give you a denser, more cohesive topping. So you can omit the almond flour, but I don’t recommend it.

Are peach bars gluten-free?

Not as written. The crumble uses almond flour, but the crust and the filling both rely on all-purpose flour. A measure-for-measure gluten-free blend is where I’d start if you want to adapt it, though I haven’t tested that version.

Can I double the recipe?

Not in one pan. A 9×13 dish is already holding five cups of fruit, and doubling the depth means the center never sets. Bake two separate pans instead, side by side if your oven fits them without crowding.
