Ingredients You’ll Need

2 cups rolled old-fashioned oats
¼ cup pure maple syrup
1 teaspoon baking powder
1 ½ teaspoons ground cinnamon
½ teaspoon sea salt
2 tablespoons coconut oil (melted)
2 teaspoons vanilla extract
1 tablespoon ground flaxseed (or 1 large egg if not vegan)

2 ripe bananas, mashed (these add natural sweetness and help bind)

Additional blueberries for topping (optional but recommended!)

How to Make Gluten Free Raspberry Crumble Bars

Now for the fun part, baking! Trust me, these are straightforward, and I promise you’ll love the process almost as much as the finished product.

Save for later

Step 1: Preheat and Prepare

Preheat your oven to 375°F.
Lightly spray an 8-inch square baking dish with cooking spray or line it with parchment paper for easy cleanup.

Step 2: Make the Crust & Crumble Mixture

In a large mixing bowl, combine oats, baking powder, cinnamon, and salt.
In a small bowl, whisk together maple syrup, melted coconut oil, vanilla, and flaxseed (or egg).
Pour the wet mixture into the dry ingredients and stir until everything is well-coated and crumbly.
This mixture will serve as both the crust and the crumble topping, so it needs to be crumbly but hold together when pressed.

Step 3: Prepare the Raspberry Filling

In another bowl, mash the bananas until smooth.
Gently fold in ½ cup of blueberries.
The bananas add natural sweetness, so you don’t need much extra sugar, FYI, I tried this with just bananas and blueberries, and it’s perfection.
Carefully fold in the remaining 1 cup of blueberries. Be gentle so you don’t burst all the berries, your bars will look prettier and stay more intact.

Step 4: Assemble the Bars

Pour the raspberry mixture into the prepared baking dish, spreading it evenly.
Crumble the oat mixture over the top, pressing lightly to create an even layer.
Scatter the remaining blueberries on top for a pop of color and extra tartness.

Step 5: Bake to Perfection

Pop it into the oven and bake for about 40 to 55 minutes.
Keep an eye on it, you’re looking for a golden top and a set middle.
If the edges brown too quickly, tent with foil to avoid burning.

Step 6: Cool and Serve

Once baked, let the bars cool in the dish for about 10 minutes.
Then, transfer to a wire rack or cut directly in the dish.
Serve warm or at room temperature, topped with extra blueberries, a drizzle of nut butter, and a splash of maple syrup.

Tips for the Perfect Bars

Use fresh or frozen blueberries, frozen works just as well, just don’t thaw them before adding.
Adjust sweetness: If you like your bars sweeter, add a drizzle of honey or extra maple syrup.
Make ahead: These bars store beautifully and only get better after a day or two.
For crispier edges: Bake a little longer, and consider broiling for the last minute, just watch closely!

Storing & Reheating

Once you’ve devoured the bars (no judgment here), here’s how to keep them fresh:

Refrigerate in an airtight container for up to 5 days.
To reheat, cover with foil and warm in a 350°F oven for about 15–20 minutes.
For individual portions, microwave for about 30 seconds to 1 minute until warm and gooey.

If you want to freeze these for later:

Wrap individual bars tightly in plastic wrap and store in a freezer-safe container.
They’ll stay good for up to 3 months.
To thaw, just leave them at room temp for a few hours or reheat in the oven.

Final Thoughts

There you have it, gluten free raspberry crumble bars that are simple, tasty, and healthy enough to make on a whim. Whether you’re gluten sensitive or just love a good berry treat, these bars won’t disappoint.
