  • 3 cups 310 g rolled oats
  • 1 cup 120 g almond flour
  • ½ tsp salt
  • ½ tsp cinnamon optional
  • ½ cup 100 g coconut oil, melted
  • cup 117 g honey (or maple syrup for vegan option)
  • 1 tbsp 32 g cashew butter (can substitute any other nut or seed butter)
  • 12 oz blackberries
  • 1 tbsp tapioca starch


  • Preheat oven to 350°F. Line an 8 x 8-in baking pan with parchment paper and set aside.
  • Combine oats, almond flour, salt, and cinnamon in a food processor. Pulse to chop oats and combine.
  • In a small pot, or microwavable bowl, melt coconut oil. Stir in honey and cashew butter.
  • Pour into dry ingredients in food processor and process until mixture comes together (make sure there are not dry spots).
  • Set aside 1 cup of oat mixture for crumb topping. Evenly distribute and press down the remaining mixture in the parchment lined baking pan. Prick the crust with a fork a few times to allow steam to escape. Bake for 10 minutes.
  • While crust is baking, add blackberries and tapioca starch to the food processor and pulse 3-4 times to break the blackberries up. If you prefer a smooth filling, process until blackberries are completely pureed. Remove the crust from the oven and pour blackberry puree over crust. Crumble reserved oat mixture evenly over blackberries. Bake for 25-30 minutes, until topping is golden brown.
  • Remove from oven and cool completely in pan for 1 hour. Refrigerate for at least 4 hours until completely set. Remove from pan by lifting the edges of the parchment paper and cut into bars.
  • Enjoy!


Bars can be stored in an airtight container at room temperature for 3 days, or up to 1 week in the refrigerator.
