Brown Sugar Peach Crumble Pie Bars Recipe Easy Fresh
Ingredients
Method
- Roll out the double crust dough from Mom’s Magic Pie Crust Recipe and press it evenly into a 9×13 inch baking pan. Trim any excess dough hanging over the edges and set aside for cinnamon sugar pie cookies.
- Peel the peaches if desired and cut them into roughly 2-inch chunks to yield about 7 cups of peach pieces.
- In a large mixing bowl, combine the peach chunks with brown sugar, Cornaby’s Ultra Gel, lemon juice, and cinnamon. Stir well until the filling is fully mixed.
- Preheat your oven to 400°F (204°C).
- Pour the peach filling mixture evenly over the prepared crust in the baking pan.
- For the crumble topping, mix together the brown sugar, cinnamon, flour, and salt in a bowl. Add the cold, chopped butter and use a pastry cutter or your fingers to blend everything until the mixture resembles coarse, damp sand that clumps when squeezed.
- Sprinkle the crumble topping generously over the peach filling, pressing lightly with your hand to create clusters.
- Bake the bars for 35 to 45 minutes, or until the topping is golden brown, the peach filling is bubbly, and the crust appears baked through.
- Remove from the oven and let the bars cool on the counter for about 30 minutes. Then transfer them to the refrigerator to chill for at least 3 hours before slicing and serving.
Notes
- Cornaby’s Ultra Gel helps keep the peach filling thick without a starchy taste, though cornstarch can be used as a substitute if needed. Store the bars covered at room temperature for up to 2 days or refrigerated for as long as 5 days to maintain a crisp crumble topping. For freezing baked bars, wrap slices tightly and freeze for up to one month; thaw in the fridge before enjoying. You can freeze unbaked bars by assembling the crust and filling only, freezing, then adding the crumble topping before baking. Bake from frozen at 425°F for 45 minutes then reduce the temperature to 350°F and bake for an additional 30 minutes.

It’s the kind of dessert that feels fancy but comes together with ingredients you probably grabbed on your last grocery run.
And here’s the best part: these bars are flexible. Serve them warm with vanilla ice cream for a weekend treat, or chill them completely and pack them up for a potluck. They travel well, they freeze like a dream, and they taste like summer no matter what month you make them.
Key Ingredients That Make It Work
Let’s talk about what’s doing the heavy lifting here. The double pie crust is your foundationbuttery, flaky, and sturdy enough to hold all that juicy peach goodness without falling apart. If you’ve got a go-to crust recipe, use it. If not, the one linked in the ingredients is foolproof.
The peach filling is where the flavor lives. Fresh peach chunks get tossed with brown sugar, a squeeze of lemon juice, and cinnamon. The brown sugar adds that deep, caramel-like sweetness that white sugar just can’t match. And the lemon juice? It brightens everything up and keeps the peaches from tasting flat.
Now, here’s the ingredient you might not have heard of: Cornaby’s Ultra Gel. This stuff is a game-changer. It thickens the peach juices without any chalky aftertaste or gummy texture. If you can’t find it, cornstarch works in a pinch, but Ultra Gel is worth ordering online. It keeps your bars sliceable and your filling thick and jammy.
| Ingredient | What It Does | Swap Option |
|---|---|---|
| Double Pie Crust | Holds the filling, adds buttery flavor | Store-bought crust or graham cracker base |
| Brown Sugar | Deep caramel sweetness | Coconut sugar or maple sugar |
| Ultra Gel | Thickens filling without starch taste | Cornstarch (use same amount) |
| Peaches | Star of the show | Nectarines or frozen peaches (thawed, drained) |
| Butter (topping) | Creates crispy, golden crumble | Coconut oil or vegan butter |
The Crumble Topping
This is where texture happens. Cold butter gets worked into brown sugar, flour, cinnamon, and a pinch of salt until it looks like wet sand. When you squeeze it in your hand, it should clump together. Those clumps bake up into crispy, buttery nuggets that contrast perfectly with the soft peaches underneath.
Step-by-Step: How to Make Them
Start by rolling out your pie crust and pressing it into a 9×13-inch baking pan. Trim any overhang and save those scraps for cinnamon sugar cookies later. No need to par-bakethis crust can handle it.
Peel your peaches (or don’tthe skin softens as it bakes and adds a rustic touch), then chop them into 2-inch chunks. Toss them in a big bowl with brown sugar, Ultra Gel, lemon juice, and cinnamon until every piece is coated. Pour the whole mixture over the crust and spread it out evenly.
Pro Tip: Squeeze handfuls of the crumble topping as you sprinkle it over the fruit. This creates those irresistible clumps that get extra crispy in the oven.
Bake at 400°F for 35 to 45 minutes. You’re looking for a golden-brown top, bubbling fruit around the edges, and a crust that’s cooked through. Let the bars cool on the counter for 30 minutes, then finish chilling them in the fridge for at least 3 hours before slicing. This step is essential if you want clean cuts.
| Step | Time | What to Watch For |
|---|---|---|
| Prep crust & filling | 20 minutes | Crust should fit snugly in pan |
| Bake | 35–45 minutes | Top golden, fruit bubbling |
| Cool (counter) | 30 minutes | Bars firm up slightly |
| Chill (fridge) | 3 hours | Filling sets completely |
Tips, Tweaks, and Troubleshooting
If your filling seems runny after baking, you probably skipped the fridge time. The Ultra Gel needs that chill period to fully set. If you’re in a hurry, pop the pan in the freezer for an hour instead.
Want to make these ahead? Assemble the crust and filling, then freeze the whole pan before adding the topping. When you’re ready to bake, sprinkle on the crumble and bake from frozenjust add 10 to 15 minutes to the bake time.
Flavor Twists:
- Add a handful of fresh blueberries or raspberries to the peach filling
- Swap half the peaches for apricots for a tangy twist
- Stir a tablespoon of bourbon into the filling for a grown-up version
- Use almond flour instead of all-purpose in the topping for a nutty, gluten-friendly option
Note: If you’re using frozen peaches, thaw and drain them well. Pat them dry with a towel before tossing with the other filling ingredients to avoid a watery mess.
Serving and Storage
Serve these bars cold, at room temp, or gently warmed. A scoop of vanilla ice cream or a dollop of whipped cream takes them over the top. They’re perfect for backyard barbecues, potlucks, or just because it’s Tuesday and you deserve something sweet.
Store covered at room temperature for up to 2 days, or refrigerate for up to 5 days. The crumble stays crisp longer when chilled. For longer storage, wrap individual slices in plastic wrap and freeze for up to a month. Thaw in the fridge overnight before serving.
| Storage Method | How Long | Best For |
|---|---|---|
| Room Temp (covered) | 2 days | Same-day serving |
| Refrigerator | 5 days | Keeping topping crisp |
| Freezer (baked, wrapped) | 1 month | Make-ahead dessert stash |
| Freezer (unbaked) | 3 months | Bake-from-frozen convenience |
Shortcut: Use a food saver to wrap individual slices before freezing. They’ll stay fresh longer and you can grab one whenever a craving hits.
Expert Says: The Secret to Perfect Brown Sugar Peach Crumble Pie Bars
According to pastry chef and food writer Erin Jeanne McDowell, brown sugar is key to achieving depth in fruit desserts:

FAQs (Brown Sugar Peach Crumble Pie Bars)
Can I use frozen peaches instead of fresh peaches?
Yes, frozen peaches work well for this recipe. Thaw them completely and drain excess liquid before using. Pat them dry with paper towels to prevent soggy bars. You may need to bake an extra 5-10 minutes to account for additional moisture.
How long do these bars stay fresh?
Store covered at room temperature for up to 3 days or refrigerate for up to a week. For longer storage, wrap individually and freeze for up to 3 months. The freezer friendly dessert maintains its texture beautifully when properly wrapped.
What makes the crumble topping extra crispy?
Cold butter is key to achieving a crispy topping. Cut it into small cubes and keep refrigerated until mixing. The brown sugar oat topping gets its crunch from the oats and proper butter-to-flour ratio. Don’t overmix the topping ingredients.
Can I make these gluten-free?
Absolutely! Replace all-purpose flour with a 1:1 gluten-free baking flour blend. Make sure your oats are certified gluten-free. The texture remains deliciously crumbly with this simple substitution.
Why are my bars falling apart when cutting?
Let the bars cool completely before cutting – this takes about 2 hours. Use a sharp knife and clean it between cuts. Chilling the pan for 30 minutes before slicing also helps create clean, neat squares that hold together perfectly.
