Blueberry Filling

  • 2 cups blueberries fresh or frozen
  • zest of one lemon
  • 2 Tablespoons water
  • 1 Tablespoon arrowroot powder or cornstarch


  • Preheat oven to 350° F. Line a square (8x8) baking dish with parchment paper.
  • Add blueberries, lemon zest, water and arrowroot powder into a saucepan. Bring to a boil over medium-high heat. Reduce heat to a simmer and stir constantly for about 3-5 minutes or until mixture has thickened and some of the blueberries have started to pop. Remove from heat and set aside.
  • Combine oat flour, rolled oats, coconut sugar and sea salt in a medium mixing bowl.
  • Add coconut oil to the mixture and using your hands or a spoon combine mixture until it forms into a crumble.
  • Measure out ⅔ cup of the oatmeal crumble mixture for the topping into small bowl and stir in the hemp hearts.
  • Add remaining oatmeal crumble mixture to the prepared baking dish and evenly press into down using your hands to form the crust.
  • Pour blueberry filling on top of your crust.
  • Sprinkle the oatmeal + hemp crumble on top.
  • Bake for 35-40 minutes until the bars are golden brown on top and the blueberry filling is bubbling and sticking to the edges of the pan. Remove from oven and place on a wire rack to cool completely. Be patient, if you don’t let them cool before removing them from the pan they will fall apart.
  • Once cool, cut into 12 bars and enjoy right away or chill in the fridge before serving. I personally like the bars chilled, after they've been in the fridge for a bit.
