Peach Raspberry Breakfast Bars are my kind of breakfast bar: a jammy fruit layer tucked between a sturdy oat crust and a buttery crisp crumble on top. They eat like a handheld fruit crisp, which is exactly what I want with my morning coffee.

The peaches keep things soft and mellow, and the raspberries add that little tart edge that makes the whole pan taste brighter. I also like how the oat crumble bakes up toasty and crumbly but still slices clean once it’s cooled.

I make these when I want something easy to grab for breakfast, but I’ll be honest, I snack on them all day. They’re especially good for make-ahead mornings and for using up summer fruit before it goes too soft.

Why You’ll Love This Recipe

Real breakfast-bar texture: The bottom is sturdy and a little chewy, and the top is crisp and crumbly. It holds together well once it’s fully cooled.

Jammy fruit center: The peach and raspberry layer bakes up thick and spoonable, almost like quick homemade jam in the middle.

Easy to slice and serve: Parchment paper makes it simple to lift the whole slab out and cut neat bars.

Great with fresh or frozen fruit: Fresh peaches are best, but frozen raspberries work really well and help keep the filling from turning too streaky.

Not fussy: No mixer, no complicated steps, and nothing delicate. It’s the kind of pan bake I trust for busy weeks.

Key Ingredients

Pan and prep

Cooking spray: Just a light coat helps the parchment stay put and keeps the corners from sticking.
Parchment paper: I like leaving a little overhang on two sides so you can lift the bars out in one piece.

Crust and crumble

Old fashioned oats: These give the crust that hearty chew. Quick oats work in a pinch, but the texture is softer.
All purpose flour: I use regular flour here for structure so the base doesn’t crumble when you slice.
Light brown sugar: Adds a warm sweetness and helps the crumble bake up a little crisp. Dark brown sugar is fine too.
Baking powder: A small lift so the crust doesn’t bake up too dense.
Ground cinnamon: Just enough to make the oats taste a little toasty and bakery-like.
Fine salt: Don’t skip it. It keeps the crust from tasting flat, especially with sweet fruit.
Unsalted butter: Melted butter is what makes this easy and gives that classic crumb-bar flavor.
Vanilla extract: A little vanilla rounds out the crust and ties it to the fruit filling.

Fruit filling

Peaches: I use ripe but firm peaches so they hold their shape. Dice them about the same size so they bake evenly.
Raspberries: Fresh is great, but frozen is honestly easier here. Add them straight from frozen so they don’t bleed as much.
Granulated sugar: Sweetens the fruit and helps it turn glossy and jammy as it bakes. If your peaches are super sweet, you can cut this back.
Lemon juice: Brightens the filling and keeps it from tasting heavy.
Cornstarch: This is what thickens the fruit so you get bars instead of a runny fruit layer.
Vanilla extract: Makes the fruit taste a little more “finished.”

Recipe Instructions

Preheat the oven: Heat the oven to 350°F. Line an 8-inch square pan with parchment paper, leaving an overhang on the sides, then lightly grease.
Mix the crumble: In a large bowl, mix the oats, flour, brown sugar, baking powder, cinnamon, and salt. Stir in the melted butter and vanilla until the mixture is clumpy.
Press the crust: Press about two thirds of the oat mixture firmly into the prepared pan in an even layer.
Mix the filling: In a bowl, toss the peaches and raspberries with the granulated sugar, lemon juice, cornstarch, and vanilla until evenly coated.
Add the fruit: Spread the fruit mixture evenly over the crust.
Top with crumble: Sprinkle the remaining crumble evenly over the fruit and lightly press it down so it adheres.
Bake: Bake for 38 to 42 minutes, until golden on top and bubbling around the edges.
Cool and slice: Cool completely in the pan for at least 2 hours. Lift out using the parchment overhang, then slice into bars.

My Tips!

This is the section that separates “good” from “wow.” If you read only one part of this post, make it this one — it’s where I reveal my recipe trick.

Recipe Tips & Tricks

Use ripe but firm peaches. If they’re too soft and juicy, the filling can get a little loose. Firmer peaches bake up jammy but still hold some shape.

Dice the peaches evenly. Small, even pieces cook at the same speed, so you don’t end up with a few crunchy chunks mixed in.

Add frozen raspberries straight from the freezer. This keeps them from breaking down too quickly when you toss the filling, and the color stays a little cleaner.

Press the bottom layer firmly. A tight-packed crust is what helps the bars lift and slice without crumbling apart.

Let the bars cool all the way. The filling thickens as it sits. If you cut too soon, the fruit layer can slide and look messy.

Simple tweaks

Here’s where the fun begins — a few simple tweaks can turn this recipe from casual treats into the star of any party.

Serving Suggestions

Greek yogurt: I like a bar with a scoop of plain or vanilla Greek yogurt on the side. If you want it a little sweeter, drizzle the yogurt with honey.
Coffee or tea: These are really good with coffee, especially something not too sweet. Herbal tea (like peach or berry) is nice too.
Extra fruit: Serve with fresh raspberries or sliced peaches when they’re in season. It makes the plate feel a little more like breakfast.
Warm-up option: If you want a softer bar, warm one briefly and eat it with a fork. It’s closer to fruit crisp that way.

Eat it later

This section explains how to store leftovers properly and how far in advance the recipe can be prepared.

Storage and Make Ahead

Store leftovers covered in the fridge for up to 4 days. I usually keep them right in the pan or move them to a container once sliced.

For a softer texture, you can warm an individual bar in the microwave for a few seconds. If you like them more firm and snacky, eat them cold from the fridge.

You can also make this recipe ahead and bake it the night before. Let it cool completely before covering, so the topping stays more crisp.

If you want them to last longer, freeze individual portions and thaw in the fridge overnight. They slice and wrap easiest after they’ve fully cooled.

Recipe FAQs

Can I use frozen peaches?

You can, but thaw them first and drain off excess liquid. Frozen peaches can release a lot of juice, and the filling can end up a little looser if you don’t.

Do I need to peel the peaches?

I prefer peeled peaches here because the filling looks smoother and the texture is more jammy. If you don’t mind bits of peel, you can leave them on.

How do I know when the bars are done baking?

Look for a golden top and bubbling around the edges of the pan. The center may still look a little soft, but it will set up as it cools.

Can I reduce the sugar?

Yes. For a less sweet pan, reduce the granulated sugar in the filling to 1/4 cup, especially if your peaches are very ripe.

Can I make these dairy free?

Swap the melted butter for melted coconut oil in a 1:1 swap. I find the bars slice best if you chill them a bit longer before cutting.
