Berry Chia Crumble Bars

These crumble bars are a delicious cross between a cereal bar, and traditional fruit crumble

If you’re anything like me and love the crumble topping in a traditional crumble, but always mainly eat the crumble part and only a bit of the fruit, then you’ll love this recipe

An oat crumble base, with a strawberry and raspberry chia jam centre and an oat crumble topping, these bars are the perfect snack or dessert

Completely refined sugar free, vegan and gluten free and ready within 30 minutes

Strawberry & Raspberry Chia Jam


  • 1 cup frozen raspberries

  • 2 cups frozen strawberries

  • 2 tbsp maple syrup

  • 2 tbsp cornstarch

  • 3 tbsp chia seeds

  • 1.5 tbsp lemon juice


  1. Remove the frozen fruit from the freezer

  2. Place the strawberries and raspberries in a jug and pour boiling water over them.

  3. Let it soak for a few minutes, then drain the excess water by pouring them into a sieve.

  4. Repeat this until mostly thawed.

  5. Place the berries back into the sieve and press down on the berries to strain out excess liquid, breaking up the strawberries as you go

  6. In a bowl, mix the mashed berries with the chia seeds, cornstarch, maple syrup and lemon juice

  7. Set aside for ~10-20 mins whilst you mix up and parbake the base (instructions below)

Oat crumble base & topping



  • ¾ cup coconut sugar

  • 1 cup rolled oats

  • 1/2 cup oat flour

  • 1/2 cup gluten free 1-1 flour (I use Schar Universal Mix it)

  • ½ tsp baking powder

  • 1/4 tsp salt


  • 1 tsp vanilla extract

  • 1/2 cup melted coconut oil

  • 2 tbsp maple syrup


  1. Preheat the oven to 180°C (fan)

  2. Mix the dry ingredients together in a large mixing bowl

  3. In a separate bowl or jug mix the wet ingredients

  4. Make a well in the centre of the dry ingredients and pour in the wet ingredients, mixing with a fork in the centre first, then moving outwards until fully combined

  5. With around 3/4 of the mixture (leaving around 1/4 in the bowl still), flatten to cover the base of a square dish lined with baking parchment ~20cm

  6. Bake this base for 10 minutes

  7. Remove from the oven and allow to cool for a few minutes

  8. Cover the base in the jam

  9. Sprinkle the crumble topping over the jam

  10. Return to the oven and bake for ~20 minutes or until the crumble begins to appear slightly golden

  11. Allow to cool fully (important!) before slicing into bars

  12. Store in an airtight container for ~3 days
