Easy Baked Mixed Berry Crumble Bars Recipe

I first made these mixed berry crumble bars on a random Tuesday night when I had a fridge full of berries about to go bad and a craving for something sweet but not sinful.

Back then, I was constantly tired and craving sugar at 3pm like clockwork. I’d usually reach for a packaged granola bar… but I always felt worse after.

These bars changed that. They’re made with simple, wholesome ingredients, sweetened with maple syrup, and have that irresistible soft-crunchy texture that hits the spot every time.

I pack them in lunchboxes, serve them with coffee when girlfriends come over, and always have a stash in the freezer. You're going to love them. đź’ś

 

Mixed Berry Crumble Bars

Ingredients:

For the base + crumble topping:

  • 1 ½ cups almond flour

  • 1 cup rolled oats (gluten-free if needed)

  • ¼ cup coconut sugar

  • ½ tsp cinnamon

  • ¼ tsp salt

  • â…“ cup melted coconut oil

  • 2 tbsp maple syrup

  • 1 tsp vanilla extract

For the berry filling:

  • 2 cups mixed berries (fresh or frozen — I love a combo of blueberries, raspberries, and chopped strawberries)

  • 2 tbsp maple syrup

  • 1 tbsp arrowroot starch or cornstarch

  • 1 tsp lemon juice

  • ½ tsp vanilla extract

 

Instructions:

  1. Preheat oven to 350°F (175°C) and line an 8x8 inch pan with parchment paper.

  2. In a large bowl, mix almond flour, oats, coconut sugar, cinnamon, and salt. Add melted coconut oil, maple syrup, and vanilla. Stir until crumbly.

  3. Set aside ¾ cup of the crumble mixture for the topping. Press the rest firmly into the bottom of the pan.

  4. In a separate bowl, combine berries, maple syrup, starch, lemon juice, and vanilla. Stir gently to coat.

  5. Pour berry mixture over the crust. Sprinkle remaining crumble on top.

  6. Bake for 30–35 minutes, or until top is golden and berry filling is bubbling.

  7. Cool completely before slicing into bars (this helps them set!). Chill in the fridge for firmer bars.

 

Sarah’s Tips:

  • Fresh vs. frozen berries: Both work great! Just thaw and drain frozen berries first.

  • Make it nut-free: Swap almond flour for oat flour and add a bit more coconut oil if needed.

  • Add-ins: A handful of chopped walnuts or shredded coconut takes it to the next level.
