These blueberry crumble bars are fresh, flavorful and easy to make. They’re naturally gluten free, vegan and perfect with a dollop of coconut whipped cream on top!





  • 3 heaping cups fresh blueberries
  • 1/3 cup maple syrup
  • Juice from 1 lemon
  • 1 tbsp arrowroot starch


  1. Preheat the oven to 350 degrees Fahrenheit.
  2. In a large mixing bowl, whisk together the baking powder, salt, cinnamon, oats and almond flour.
  3. Add in all remaining ingredients and use a fork to mash the butter or oil into all ingredients. 
  4. The dough shouldn’t be too wet, but it should be dry either, so keep mixing until the wet ingredients are well incorporated.
  5. Add about 2/3 of the dough to an 8×8 pan lined with parchment paper. Press down firmly with your hands.
  6. Bake for 10 minutes and set aside the remaining dough.
  7. While baking, add the blueberries, lemon juice and maple syrup to a pot on the stove. Heat over low heat until the blueberries start to melt and bubble. 
  8. Whisk in the starch and let simmer for about 1 minute to allow it to thicken. 
  9. Remove from heat.
  10. When the crust is done baking, remove from the oven and let cool for 5 minutes.
  11. Add the blueberry mixture to the crust and crumble on the remaining dough on top.
  12. Bake, uncovered, for 25-30 minutes or until the crust is golden brown.
  13. Remove from the oven and let cool for at least 1 hour before slicing.


You can use any berry in place of blueberries if you prefer.

You can use fresh or frozen berries for this recipe, but I recommend using fresh if you can. Frozen berries will release more moisture and can make the crust and bit soggier. 

You want the oil/butter to be softened, but not completely melted. I usually use butter and will slice it into 1 tbsp bits and microwave for about 15 seconds and then add that to the dough. Coconut oil usually melts faster, so it should only need about 10-15 seconds in the microwave to soften.

Be sure to use almond flour from blanched almonds, not almond meal. 

My favorite almond butter is the raw almond butter from Trader Joe’s. If you have access to this one, definitely get it! Roasted almond butters have a stronger flavor, so I always prefer raw in baking.

If you only have rolled oats, you can pulse them a few times in a food processor to get them into a quick oat texture.

The arrowroot can be subbed for cornstarch or tapioca starch.
