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:
-
Preheat oven to 350°F (175°C) and line an 8x8 inch pan with parchment paper.
-
In a large bowl, mix almond flour, oats, coconut sugar, cinnamon, and salt. Add melted coconut oil, maple syrup, and vanilla. Stir until crumbly.
-
Set aside ¾ cup of the crumble mixture for the topping. Press the rest firmly into the bottom of the pan.
-
In a separate bowl, combine berries, maple syrup, starch, lemon juice, and vanilla. Stir gently to coat.
-
Pour berry mixture over the crust. Sprinkle remaining crumble on top.
-
Bake for 30–35 minutes, or until top is golden and berry filling is bubbling.
-
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.
