There’s just something magical about fresh peaches, isn’t there? For me, they instantly bring back memories of sunny summer afternoons, sticky fingers, and that incredible, juicy sweetness. I’ve always loved baking with them, but finding a truly delicious gluten-free treat that tastes just as good as the “regular” version can be a challenge. That’s why I poured my heart into perfecting these Gluten Free Peach Crumble Bars, and let me tell you, they are a game-changer! They capture all that wonderful peachy flavor with a buttery, zesty shortbread crumble that you won’t believe is gluten-free.
Why You’ll Love This Gluten Free Peach Crumble Bars
- They’re incredibly easy to make, even for beginner bakers!
- The shortbread base is perfectly buttery and holds its shape beautifully.
- Juicy, sweet peaches burst with flavor, balanced by a hint of lemon.
- They’re wonderfully versatile – perfect for dessert, breakfast, or a snack!
Ingredients You’ll Need
- Gluten Free Flour Blend: This is the star of our gluten-free shortbread! I use a plain blend without xanthan gum, but if yours has it, just omit the extra xanthan gum in the recipe.
- Caster/Superfine or Granulated Sugar: Either works great here to give our shortbread and peach filling that perfect sweetness.
- Lemons: We’re using both the zest for the shortbread and the juice for the filling. Organic, unwaxed lemons are best for zest since you’re using the peel!
- Unsalted Butter: Make sure it’s softened, but not melted. This helps create that tender, crumbly shortbread texture.
- Vanilla Bean Paste or Extract: Vanilla paste gives a richer flavor and those lovely little speckles, but extract is perfectly fine too!
- Xanthan Gum: This is our gluten-free secret weapon! It helps bind the dough and gives it structure since we don’t have gluten.
- Fresh Peaches: The star of the show! Choose peaches that are ripe and flavorful but not too soft. We want them to hold up a bit during baking.
- Cornstarch (US)/Cornflour (UK): This thickens our peach filling beautifully, preventing it from being too runny.
How to Make Gluten Free Peach Crumble Bars Step by Step
First things first, let’s get our peaches ready! If you want to peel them, it’s super easy. Just score a little “X” on the bottom of each peach, then pop them into boiling water for about 30-60 seconds. This is where the magic happens – the skin will loosen right up! After their hot bath, dunk them into an ice water bath to stop the cooking, and you’ll be able to peel them effortlessly. Whether you peel them or not, slice them into nice ½-inch wedges.
Now for the shortbread! Preheat your oven to 375ºF (190ºC) and line a 9-inch square pan with parchment paper, leaving some overhang. This little trick will make it so much easier to lift the bars out later. Rub the lemon zest into the sugar with your fingertips – trust me, this step makes the shortbread extra fragrant! Then, mix in the softened butter and vanilla with a wooden spoon until combined. Don’t worry about overmixing; we’re not trying to aerate it.
In a separate bowl, whisk together your gluten-free flour, xanthan gum, and salt. Add these dry ingredients to your butter mixture and mix until it starts clumping. Then, give it a quick knead to form a crumbly dough. Press about two-thirds of this dough into the bottom of your prepared pan, smoothing it into an even layer. Top this with your sliced peaches, making sure to drizzle any leftover juices from the bowl over them. Finally, crumble the remaining dough over the peaches, aiming for an even coverage but letting some of that beautiful peach peek through. Bake for about 50-55 minutes until the crumble is golden brown and the peach filling is bubbling away in the center. Allow them to cool completely before slicing – this is crucial for neat bars!
My Top Tips for Success
- I always leave parchment paper overhang when lining the pan; it makes removing the whole slab so much easier.
- Trust me on this one: rubbing the lemon zest into the sugar really boosts the citrus flavor in the shortbread.
- Don’t over-cream the butter and sugar for the shortbread. We want a tender, crumbly texture, not a cakey one.
- For the neatest slices, I recommend chilling the bars in the fridge for at least 30 minutes after they’ve cooled completely.
- If you’re serving these warm with ice cream, just know they’ll be a bit more delicate to cut, but oh-so-worth-it!
Common Mistakes to Avoid
- Not cooling completely before slicing: If you cut into the bars while they’re still warm, they’ll be very crumbly and won’t hold their shape well. Patience is key here!
- Overly ripe peaches: If your peaches are too soft, they can become mushy in the filling. Choose flavorful but slightly firm peaches.
- Forgetting xanthan gum (if your blend doesn’t have it): Xanthan gum is essential in gluten-free baking to provide structure. Without it, your shortbread might be too crumbly.
- Not lining the pan properly: Without enough parchment overhang, it can be tricky to get the bars out of the pan in one piece.
How to Store Gluten Free Peach Crumble Bars
- At room temperature: Store in an airtight container for up to 2-3 days.
- In the refrigerator: Store in an airtight container for up to 5 days.
- In the freezer: Wrap individual bars tightly in plastic wrap, then place in a freezer-safe bag or container for up to 2-3 months. Thaw at room temperature or gently warm.
Frequently Asked Questions
Can I use frozen peaches?
Yes, you can! Thaw them completely and drain any excess liquid before using, as frozen peaches tend to release more water.
Do I have to peel the peaches?
No, you don’t! Peeling is optional. The skin adds a bit of texture and color, and it’s perfectly fine to leave it on if you prefer.
Can I make these dairy-free?
I haven’t tested a dairy-free version, but you could try substituting the butter with a good quality dairy-free stick butter alternative. The texture might be slightly different.
Why did my shortbread dough seem too crumbly?
Gluten-free doughs can sometimes feel a bit more crumbly than traditional doughs. Just keep kneading it gently; the warmth from your hands will help bring it together into a cohesive, crumbly ball.
I truly hope you give these Gluten Free Peach Crumble Bars a try! They are such a delightful treat, bursting with summer flavor and that comforting crumble. If you make them, please let me know how they turn out – I absolutely love hearing from you!
