- Gluten-free rolled oats (1 cup): The heart of the topping, giving you that beloved chewy-crispy texture.
- Almond flour (1/2 cup): Adds a subtle nuttiness and tender crumb while keeping it moist and gluten-free.
- Brown sugar or coconut sugar (1/2 cup): Provides warmth and caramel notes to the crumble topping.
- Cold unsalted butter (1/2 cup, cut into bits): Gives the topping a rich, flaky texture that melts in your mouth.

How to Make Easy Gluten-Free Oat Berry Crumble Recipe
Step 1: Prepare and Preheat
Start by preheating your oven to 350°F and positioning the oven rack in the center. Lightly grease an 8×8-inch baking dish to keep your crumble from sticking and make cleanup a breeze.
Step 2: Toss the Berries
In a medium bowl, toss your mixed berries with honey or maple syrup, lemon juice, and gluten-free cornstarch. This coating not only sweetens but also ensures the juices thicken beautifully as the berries bake, leaving you with a luscious filling.
Step 3: Layer the Berry Mixture
Pour the glossy berry mixture into the prepared baking dish and smooth it out evenly. This base is where all the juicy magic begins, creating that tender fruit layer we’re craving.
Step 4: Combine the Crumble Topping
In a separate bowl, mix the gluten-free rolled oats, almond flour, brown or coconut sugar, cinnamon, and sea salt until well blended. This combination ensures a balance of flavors and textures in the topping.
Step 5: Add Butter and Form Crumbs
Add the cold, cubed butter to the oat mixture. Using your fingers or a pastry cutter, blend everything until it resembles coarse sand with small pea-sized pieces, which will bake into a crisp, crumbly topping perfect for scooping.
Step 6: Assemble and Bake
Sprinkle the crumble evenly over the berry layer. Place the dish in the oven and bake for 30 to 35 minutes until the topping is golden and the berries are bubbling joyfully beneath.
Step 7: Rest Before Serving
Once baked, remove the crumble from the oven and let it rest for about 10 minutes. This helps the filling set slightly, making it easier to serve while still gloriously warm.
How to Serve Easy Gluten-Free Oat Berry Crumble Recipe
Garnishes
For an extra touch of indulgence, top your crumble with a dollop of whipped cream or a scoop of vanilla ice cream that melts into the warm oats and berries. Fresh mint leaves or a dusting of powdered cinnamon can also bring an elegant pop of color and aroma.
Side Dishes
This crumble shines wonderfully on its own but pairs delightfully with a cup of rich, freshly brewed coffee or a glass of creamy almond milk. For brunch or cozy dinners, consider serving it alongside a light salad or roasted nuts to balance texture and flavors.
Creative Ways to Present
Try serving individual portions in small ramekins or mason jars for a charming presentation, perfect for gatherings or gifting. Layer the crumble with yogurt for a parfait or add chopped nuts and seeds on top for added crunch and nutrition.
Make Ahead and Storage
Storing Leftovers
Transfer any leftovers to an airtight container and refrigerate. They will keep beautifully for up to 3 days, allowing you to savor this Easy Gluten-Free Oat Berry Crumble Recipe again with minimal effort.
Freezing
You can freeze the unbaked crumble fully assembled in its baking dish, wrapped securely with plastic wrap and foil. Freeze for up to 2 months, then bake directly from frozen, adding about 10 extra minutes to the bake time.
Reheating
Reheat leftovers in a preheated oven at 325°F for 10-15 minutes until warmed through and the topping regains its crispness. Microwaving is quicker but will soften the crumble topping.
FAQs
Can I use any type of berries?
Absolutely! Fresh or frozen blueberries, raspberries, strawberries, blackberries, or any combination you love will work beautifully in this recipe and bring unique flavors and sweetness levels.
Is the cornstarch necessary?
Yes, using gluten-free cornstarch helps thicken the berry juices as they cook, preventing the crumble from becoming too watery and ensuring that luscious filling texture.
Can I substitute the almond flour?
If you have a nut allergy, try gluten-free oat flour or a seed-based flour like sunflower seed flour. These will provide similar texture, but almond flour adds a lovely nutty richness.
Is this recipe suitable for vegans?
To make it vegan, replace butter with a vegan butter alternative or coconut oil and use maple syrup instead of honey. This keeps the crumble moist and delicious without compromising flavor.
How do I make the topping extra crispy?
Using cold butter and not over-mixing the topping is key. Also, baking until the topping turns a beautiful golden brown and the berries are bubbling ensures maximum crispness and flavor.
