These White Chocolate Blueberry Crumble Bars hit a great balance. They’re fruity but still feel like dessert, with a crumble topping and a drizzle of vegan white chocolate that adds just the right touch of sweetness.

The base is made from oats and almond flour, sweetened with maple syrup. The blueberry filling is cooked with lemon and chia seeds for a thick, jammy layer that’s not too tart or too sweet. Once baked and drizzled, they’re easy to slice, easy to store, and great for breakfast, dessert, or a sweet snack.

What Makes These White Chocolate Blueberry Crumble Bars Stand Out

The best part about these bars is how layered they are. You get a soft, oat-based crust that’s gently sweet with a touch of vanilla and cinnamon. The blueberry filling is thick and jammy, brightened up with lemon juice and zest. Then there’s the crumble topping, golden and crisp, and the final drizzle of vegan white chocolate that ties everything together.

They’re fully vegan and simple to make gluten-free, making them a flexible option for different diets. No hard-to-find ingredients, just solid flavor and texture in every bite.

Why This Vegan Blueberry Dessert Works So Well

Blueberries aren’t just delicious. They’re naturally sweet, packed with antioxidants, and have that perfect burst when cooked down. Here, the filling gets a bit of help from chia seeds, which help it thicken naturally as it cools. Plus, lemon zest brings out the flavor even more, making this feel like a bite of sunshine. And by using maple syrup in the filling and crumble, you get a gentle sweetness that doesn’t overpower the fruit.

It’s a great balance between wholesome and dessert-y. The oats and almond flour bring a hearty texture, and the white chocolate drizzle adds a smooth, sweet finish that pairs perfectly with the tart berry filling.

Ingredients for White Chocolate Blueberry Crumble Bars

Crumble Base + Topping:

1 ½ cups rolled oats (gluten-free if needed)
¾ cup almond flour
¼ teaspoon salt
¼ teaspoon cinnamon (optional)
¼ cup melted coconut oil (or vegan butter)
¼ cup maple syrup
1 teaspoon vanilla extract

Blueberry Filling:

2 cups fresh or frozen blueberries
2 tablespoons maple syrup
1 teaspoon lemon zest
1 tablespoon lemon juice
1 tablespoon chia seeds (or 1 teaspoon arrowroot powder for a smoother filling)

White Chocolate Drizzle:

½ cup vegan white chocolate chips (I used Enjoy Life mini)
1 teaspoon coconut oil (optional, for smoother drizzle)

How to Make These Vegan Crumble Bars

Prep the Oven & Pan
Preheat your oven to 350°F (175°C). Line an 8×8-inch pan with parchment paper. Leave a little overhang to make lifting out the bars easier.

Make the Oat and Almond Crumble
In a mixing bowl, combine oats, almond flour, salt, and cinnamon. Stir in the melted coconut oil, maple syrup, and vanilla until the mixture looks crumbly but sticks together when pressed. Set aside ½ cup for the topping. Press the rest firmly into your pan to form the base.

Cook the Blueberry Filling
Add blueberries, maple syrup, lemon zest, lemon juice, and chia seeds to a small saucepan. Simmer over medium heat for 5 to 7 minutes until it becomes juicy and slightly thickened. Let it cool for about 5 minutes. It will firm up a bit more as it sits.

Assemble and Bake the Crumble Bars
Spread the blueberry mixture over the base, then sprinkle the reserved crumble mixture evenly on top. Bake for 25 to 28 minutes until golden on top and bubbling at the edges. Let the whole thing cool completely in the pan.

Drizzle with Vegan White Chocolate
Once cool, melt the vegan white chocolate chips with coconut oil using short bursts in the microwave or a double boiler. Drizzle over the bars using a spoon or small piping bag. Chill the pan for about 15 minutes to help set the drizzle.

Slice and Serve
Lift the bars out using the parchment, then cut into 12 small or 9 large squares. They’re ready to eat, or chill them for even cleaner slices.

How to Store These Gluten-Free Crumble Bars

Store these bars in an airtight container in the fridge for up to 5 days. If you want to keep them longer, freeze them in a single layer or with parchment between pieces. They’ll keep for about 2 months frozen and taste just as good thawed.

Vegan White Chocolate Crumble Bar Variations

Change the fruit: Raspberries, blackberries, or a combo of berries all work well in place of the blueberries.
Add some crunch: Stir chopped walnuts or sliced almonds into the crumble topping for texture.
Go extra: Swirl a bit of the melted white chocolate into the blueberry layer before baking. It adds a little creamy sweetness to every bite.

FAQs About White Chocolate Blueberry Crumble Bars

Can I use frozen blueberries?
Yes. No need to thaw them first, just add a couple of extra minutes to the cooking time.

Is this recipe gluten-free?
It can be. Just make sure to use certified gluten-free oats.

How do I make sure the bars hold together well?
Firmly press the base into the pan so it’s compact and even. After baking, let the bars cool completely, then chill them for 15–20 minutes before slicing. This helps everything set and hold its shape.

What if I don’t have almond flour?
You can try oat flour or a blend of oat and coconut flour. The texture will change slightly but still work.

Do I need to use white chocolate?
Not at all. You can skip it or substitute with dark chocolate, but it does add a nice creamy note.
