Gluten-Free Vegan Blueberry Crumble Bars

These Gluten-Free Vegan Blueberry Crumble Bars are the perfect dessert: a crunchy base topped with juicy, jammy blueberries and a “buttery” crumble topping. They’re an excellent alternative to Blueberry Pie!

Why does this recipe use brown rice flour?

You can use white rice flour or gluten-free flour, but I found the texture was much better with brown rice flour. If you can’t find brown rice flour in your local supermarket, you’ll be able to find it in local health stores or online.

How to make these Gluten-Free Vegan Blueberry Crumble Bars

Scroll down to the bottom of the post for the full recipe.

• Mix together the ingredients for the dough in a glass mixing bowl.

• Transfer one half into a square baking tin.

Tip: Line the tin with greased baking paper to make it easier to remove the bars after.

• Use your fingers to push the mixture all the way to the edges, then use a spatula to press down on it until the surface is completely even.

• Bake in oven for 10 minutes – you’ll be baking this again so you don’t want to over-bake at this stage!

• Place the blueberries and maple syrup in a pan.
• Leave to cook on a low heat, stirring occasionally, for about 20 minutes until soft.
• Dissolve the cornflour (cornstarch) in a tiny splash of water in a small bowl.
• Once the blueberries have cooked, add the cornflour and water mixture and mix well.
• Once the blueberries have thickened (takes about 30 seconds), turn off the heat.

• Place the cooked blueberries over the cooked base until completely evenly covered.

• Use your fingers to crumble the rest of the dough mixture over the top until it is all used up and the blueberries are completely covered.

• Bake in the oven for around 20 minutes, or until golden brown.

• Leave to cool completely before cutting.

How long do these Gluten-Free Vegan Blueberry Crumble Bars keep for?

These Blueberry Crumble Bars do taste best when fresh, but they keep covered in the fridge for up to a few days.

Substitutions you can make to this recipe:

• you can replace the coconut oil with coconut butter
• you can use any type of liquid sweetener: maple syrup, agave syrup, brown rice syrup etc
• the ground almonds (almond meal) can be replaced with ground walnuts
• for a nut-free version, use ground sunflower seeds instead of ground almonds and use a nut-free plant-based milk

• you can replace the brown rice flour with plain flour if you’re not gluten-free
• you can use any type of plant-based milk: almond milk, cashew milk, oat milk, rice milk, soy milk etc

Ingredients

For the crumble:

• 30 g (1/8 cup) coconut oil  (or sub coconut butter)
• 10 tablespoons maple syrup  (or sub any other similar sweetener)
• 1 tablespoon unsweetened almond milk (or any other plant-based milk)
• 150 g (1 1/4 cup) ground almonds (almond meal) *
• 150 g (1 cup) brown rice flour ** (or sub plain flour if not gluten-free)
• Pinch salt

For the blueberries:

• 450 g (4 1/2 cups) fresh blueberries
• 6 tablespoons maple syrup (or sub any other similar sweetener)
• 5 teaspoons cornflour (cornstarch) (or sub tapioca starch)

Instructions

For the crumble:

• Preheat oven to 180 degrees Celsius (350 degrees Fahrenheit)
• Place the coconut oil in a large bowl and melt over a saucepan of boiling water or in the microwave
• Add the maple syrup, milk, ground almonds, brown rice flour and salt and mix well – add an extra splash of milk if it’s looking too dry to combine
• Divide the dough in half
• Transfer one half of the dough into a square or rectangular baking tin lined with greased baking paper – I used a 23cm/9inch square baking tin
• Use your fingers to push the mixture all the way to the edges, then use a spatula to press down on it until the surface is completely even
• Bake in oven for 10 minutes
• Place the remaining half of the dough in the fridge while you make the rest (this will help it firm up and make it easier to crumble over the top after)

For the blueberries:

• Place the blueberries and maple syrup in a pan with a lid
• Leave to cook on a low heat, stirring occasionally, for about 20 minutes until softened
• Dissolve the cornflour in a tiny splash of water in a small bowl
• Once the blueberries have cooked, add the cornflour and water mixture and mix well
• Once the blueberries have thickened (takes about 30 seconds), turn off the heat

To assemble:

• Place the cooked blueberries over the cooked base until completely evenly covered
• Use your fingers to crumble the rest of the dough mixture over the top until it is all used up and the blueberries are completely covered
• Bake in the oven for around 20 minutes, or until golden brown
• Leave to cool completely before cutting into squares
• Tastes best when fresh, but keeps covered in the fridge for up to a few days

Notes

*You can alternatively use almond flour

**You can use white rice flour or gluten-free flour but the texture is much better with brown rice flour. 

• You can add ground cinnamon to the blueberries.
• You can add flaked or desiccated coconut or oats to the crumble topping.
