Here’s a simple but carefully selected lineup of ingredients that make these Almond Flour Blackberry Crumb Bars Recipe shine. Each element brings something special to the table, from texture and flavor to a beautiful golden color and natural sweetness.

2 ½ cups superfine almond flour: The base of our crust and topping, providing a tender, buttery texture without gluten.
4 Tbsp coconut oil: Adds moistness and rich flavor, plus it helps crisp up the crumb layer perfectly.
3 Tbsp pure maple syrup: A natural sweetener that enhances the nutty flavor and balances the tart blackberries.
Pinch sea salt: Elevates the overall flavor, bringing out the sweetness while adding depth.
3 cups fresh or frozen blackberries: The star of the filling, offering juicy bursts of tartness and beautiful color.
3 Tbsp water: Helps the berries cook down into a luscious filling.
2 Tbsp pure maple syrup: Sweeter for the blackberry layer, balancing the fruit’s natural acidity.
1 Tbsp tapioca flour: Gives the filling a perfect gel-like consistency without cloudiness.
Pinch sea salt: Just a touch added to the filling to enhance berry flavor.

How to Make Almond Flour Blackberry Crumb Bars Recipe

Step 1: Prepare the Crust and Topping

Start by preheating your oven to 350 degrees F and lining an 8-inch square baking pan with parchment paper to ensure easy removal. Then, combine all the ingredients for the crust and topping—almond flour, coconut oil, maple syrup, and salt—into one bowl. Mix everything together well; the texture will be similar to a dry cookie dough. Set aside about half a cup of this mixture later to use as your crumbly topping.

Step 2: Bake the Crust

After pressing the remaining dough evenly into your baking pan, poke a few holes with a fork across the surface. This allows steam to escape and keeps the crust from puffing up. Bake for 10 to 12 minutes until you see golden edges forming. It’s this pre-baking step that builds a sturdy, crisp crust that will hold all your blackberry filling without getting soggy.

Step 3: Prepare the Blackberry Filling

Next, combine fresh or frozen blackberries, water, maple syrup, tapioca flour, and a pinch of salt in a saucepan. Bring the mixture to a full boil over medium-high heat. Once boiling, reduce the heat and use a spoon or fork to mash the blackberries into smaller pieces. Continue to cook and stir for 3 to 5 minutes more until it thickens to a glossy, jam-like consistency that’s rich and bursting with flavor.

Step 4: Assemble and Bake the Bars

Pour the blackberry filling evenly over the warm crust, then sprinkle the reserved crumb mixture on top, spreading it gently to cover. Pop the pan back into the oven for about 20 to 25 minutes. You want the topping to turn golden and slightly crispy while the filling bubbles invitingly.

Step 5: Cool and Slice

Remove the bars from the oven and let them cool completely before slicing. Cooling is key for the bars to set and hold together beautifully. For a faster chill, you can first cool at room temperature for 10 to 15 minutes, then move the pan to the refrigerator to firm up the bars completely. Use a sharp knife to cut into squares, and you’re ready to enjoy!

Creative Ways to Present

Layering bars with other gluten-free cookies and fresh berries on a pretty board makes an irresistible display that’s sure to impress.

Make Ahead and Storage

Storing Leftovers

Once baked and cooled, your Almond Flour Blackberry Crumb Bars Recipe stores beautifully in an airtight container in the refrigerator for up to 7 days. This keeps the crumb topping crisp and the filling fresh. At room temperature, keep them covered, but consume within 2 days for best quality.

Freezing

You can freeze these bars for longer storage—wrap individual squares tightly in plastic wrap and then place them in a freezer bag or container. They’ll keep well for up to 3 months, making for a convenient anytime treat that’s ready when you are.

Reheating

To enjoy these bars warm, let them thaw at room temperature if frozen, then heat gently in the oven at 300 degrees F for 5 to 8 minutes or until just warmed through. Avoid microwave reheating if possible, as it can soften the crumb topping too much.

FAQs

Can I use another type of flour instead of almond flour?

Almond flour is essential here for the texture and subtle nutty flavor it provides. Using regular flour will change both the texture and flavor, and will no longer be gluten-free. For similar results, try other nut flours like hazelnut or cashew, but almond is the classic choice.

Are frozen blackberries okay to use?

Absolutely! Frozen blackberries work wonderfully for this recipe and are often more affordable and available year-round. Just thaw them slightly and drain excess juice if needed to avoid a runny filling.

What is tapioca flour and can I substitute it?

Tapioca flour is a gluten-free starch that thickens the filling and gives it a glossy finish. You can substitute with cornstarch if needed, but tapioca is preferred for the best texture and clarity.

Is this recipe dairy-free?

Yes, this Almond Flour Blackberry Crumb Bars Recipe is naturally dairy-free, using coconut oil instead of butter and maple syrup as a sweetener, making it perfect for those with dairy restrictions.

Can I make these bars ahead of time for a party?

Definitely! These bars hold up well when made a day or two in advance. Just make sure to store them properly in the fridge and bring them to room temperature or warm slightly before serving.
