For this recipe, you can use any type of frozen berries (think strawberries, mixed berries, etc.). I chose to use blueberries because they are a powerhouse of good nutrition.
They are vegan and gluten-free which makes them perfect for those following special diets. It’s also full of fiber so you can feel good about indulging your sweet tooth. The bars are great for making ahead of time as they store well in the refrigerator for up to six days.
Let’s look at how they are made.
📝 Blueberry Crumble Bars Ingredients
Filling
- 2 cups frozen berries, such as blueberries, raspberries, blackberries, and/or chopped strawberries
- 2 teaspoons lemon juice
- 2 tablespoons pure maple syrup
- 2 tablespoons chia seeds
Crumble Topping and Base
- 1 ½ cups rolled oats
- 1 cup blanched almond flour
- ⅓ cup coconut oil, melted
- ⅓ cup pure maple syrup
- 1 teaspoon pure vanilla extract
- ⅛ teaspoon finely ground Himalayan pink salt
👩🏻🍳 Instructions
Preheat the oven to 350 degrees Fahrenheit. Line an 8-inch square baking pan with parchment paper, leaving some paper overhanging the sides for easy removal of the bars.
To make the filling, heat the berries and lemon juice in a small saucepan over medium heat, stirring and crushing the berries periodically to encourage them to break down. Cook until the berries are mashed and bubbling, about 5 minutes.
Turn off the heat and stir in the maple syrup and chia seeds. Let the mixture thicken while you prepare the crumble.
To make the crumble topping and base, put all of the ingredients in a food processor and pulse until well combined and crumbly, about 45 seconds.
Press three-quarters of the crumble mixture into the bottom of the prepared baking dish and par-bake in the preheated oven for 10 minutes, or until set.
Pour the fruit mixture over the par-baked crust and use your fingers to sprinkle the remaining crumble on top.
⏲️ Baking Time
Bake for another 15 to 20 minutes, or until the topping is golden brown and the filling is bubbling. Let cool completely before lifting from the pan and slicing into bars.
Store leftover bars covered in the refrigerator for up to 6 days.
✏️ Notes
If you don’t like coconut, a neutral oil like avocado should be a good replacement.
