Peach Crumble Bars Ingredients
For the Shortbread Crust
• Unsalted Butter (226g / 1 cup) – Essential for a rich, buttery flavor and a tender texture in the crust.
• Granulated Sugar (200g / 1 cup) – Sweetens the crust and enhances the peach filling’s natural sweetness.
• All-Purpose Flour (375g / 3 cups) – Provides necessary structure to hold the chunky peaches.
For the Peach Filling
• Fresh Peaches (900g, approx. 5-6 large) – Ensure they are ripe and juicy for maximum flavor; substitute with thawed frozen peaches if needed.
• Cornstarch (15g / 2 tbsp) – Thicken the peach mixture for a perfect, jam-like consistency.
For the Oat Crumble Topping
• Old Fashioned Rolled Oats (90g / 1 cup) – Gives a comforting, chunky texture; avoid quick oats for the best result.
For the Honey Drizzle
• Pure Honey (60ml / 4 tbsp) – Adds a glossy finish and aromatic sweetness that perfectly complements the bars.
Step‑by‑Step Instructions for Peach Crumble Bars
Step 1: Prepare Shortbread Base
Begin by preheating your oven to 350°F (175°C). In a mixing bowl, cream together 1 cup of unsalted butter and 1 cup of granulated sugar until light and fluffy. Gradually mix in 3 cups of all-purpose flour to form a crumbly dough. Press about two-thirds of this mixture firmly into the bottom of a lined 9×9 inch pan. Par-bake for 12-15 minutes, until the edges turn a pale, golden color.
Step 2: Cook Peach Filling
While your shortbread base is baking, prepare the peach filling. In a saucepan over medium heat, combine approximately 5-6 large diced fresh peaches with sugar and 2 tablespoons of cornstarch. Stir gently and cook for about 5-7 minutes, allowing the mixture to simmer until it thickens and becomes jammy. Remove from heat and let it cool slightly before assembly.
Step 3: Assemble
Once the shortbread base is par-baked, spread the prepared peach filling evenly over the crust. In a separate bowl, combine the remaining shortbread mixture with 1 cup of old-fashioned rolled oats. Crumble this oat mixture generously over the peach layer to create a topping.
Step 4: Bake and Finish
Return the assembled Peach Crumble Bars to the oven and bake for an additional 25-30 minutes. Keep an eye on them until the crumble topping turns golden brown and fragrant. Once baked, remove from the oven and allow to cool completely in the pan.
Step 5: Drizzle with Honey
For the finishing touch, warm about 4 tablespoons of pure honey in the microwave for a few seconds until it’s runny. Drizzle the honey over the cooled bars in thin lines for an inviting sweetness and gloss.
Step 6: Slice and Serve
After cooling for at least two hours, lift the bars out of the pan using the parchment paper. Using a sharp knife, cut the Peach Crumble Bars into squares for serving. These delicious treats are perfect for sharing or enjoying at home!

Make Ahead Options
These Peach Crumble Bars are a fantastic option for meal prep, saving you time during busy weeknights or weekend gatherings! You can prepare the shortbread crust and peach filling up to 24 hours in advance. Simply store the prepared crust in the refrigerator, covered tightly to prevent it from drying out, and the peach filling in an airtight container. When you’re ready to bake, spread the filling over the crust and top with the oat crumble mix, then bake as directed. For the best results, drizzle the honey glaze just before serving, ensuring that the bars remain fresh and delightful—just as delicious as if you had made them all at once!

Room Temperature: If serving the bars immediately, they can be kept at room temperature for a few hours, but leftovers should always be refrigerated to ensure quality.

Expert Tips for Peach Crumble Bars
• Use Ripe Peaches: Choose juicy, ripe peaches for the best flavor; under-ripe peaches may result in a less sweet filling.

• Cool Completely: Allow the bars to cool for at least two hours to ensure clean slices; refrigerating them makes cutting easier.
• Keep an Eye on Baking: Check during the last few minutes of baking; over-baking can dry out the crumble topping and affect the texture of your Peach Crumble Bars.
• Customize Your Crumble: Feel free to add nuts, like chopped pecans or walnuts, for extra crunch and flavor!
• Storage Tips: Store any leftovers in an airtight container in the fridge for up to five days for the best taste and freshness.

Peach Crumble Bars Recipe FAQs
How do I choose ripe peaches for this recipe?
Absolutely! When selecting peaches, look for ones that are firm yet slightly soft to the touch, with a sweet aroma. Avoid peaches with dark spots all over or a shriveled skin. Ripe peaches will give you the best flavor for your filling, so it’s worth taking the time to pick the right ones!
How should I store my Peach Crumble Bars?
Very easy! Once your bars are completely cooled, store them in an airtight container in the refrigerator for up to 5 days. If you want to keep them longer, wrapping individual squares in plastic wrap and placing them in a freezer-safe bag allows them to last up to 3 months.
Can I freeze Peach Crumble Bars?
Absolutely! To freeze your Peach Crumble Bars, first allow them to cool completely. Wrap each square in plastic wrap, then place them in a freezer-safe bag. Make sure to squeeze out as much air as possible. When you’re ready to enjoy them, thaw them overnight in the fridge, or pop them in the microwave for a warm treat!
What should I do if my peach filling is too runny?
Great question! If your filling is too runny, it may be due to undercooking or the peaches releasing too much juice. Cook the peach mixture a bit longer over medium heat, stirring constantly, until it thickens to a jam-like consistency. Adding an extra tablespoon of cornstarch dissolved in a little water can also help thicken it up.
Are Peach Crumble Bars safe for pets or those with allergies?
While this recipe is delicious for humans, it’s not suitable for pets, namely dogs, as peaches contain cyanide in the pits and are high in sugar. For those with allergies, this recipe contains gluten (from the flour) and dairy (from the butter). Feel free to substitute the butter with a dairy-free alternative and use gluten-free flour for a safe option that still tastes great!
Can I use frozen peaches instead of fresh?
Absolutely! If fresh peaches aren’t available, substitute with thawed frozen peaches. Be sure to drain any excess liquid after thawing to prevent a soggy filling. This can help maintain the beautiful texture and flavor that make the Peach Crumble Bars a delight!
