Ingredients

Dry Ingredients

  • 1 cup oat flour
  • 1 cup old fashioned rolled oats
  • ½ cup coconut sugar
  • ½ teaspoon sea salt

Wet Ingredients

  • 6 Tablespoons coconut oil (room temperature/solid)
  • 2 Tablespoons water

Filling Ingredients

  • 2 cups blueberries (fresh or frozen)
  • Zest of one lemon
  • 1 Tablespoon arrowroot powder or cornstarch

Add-ins for Topping

  • 2 Tablespoons hemp hearts


Instructions

  1. Prep: Preheat oven to 350°F (175°C). Line an 8×8 inch square baking dish with parchment paper or spray with cooking spray to prevent sticking.
  2. Simmer Blueberries: In a saucepan, combine blueberries, lemon zest, water, and arrowroot powder. Bring to a boil over medium-high heat, then reduce to a simmer. Stir constantly for 3-5 minutes until the mixture thickens and some blueberries pop, creating a thick filling that coats the back of a spoon but isn’t too runny. Remove from heat and set aside.
  3. Combine Dry Ingredients: In a medium mixing bowl, mix together oat flour, rolled oats, coconut sugar, and sea salt until evenly combined.
  4. Form Crumble: Add coconut oil to the dry mixture. Using your hands or a spoon, combine until a crumbly texture forms that holds together when pressed.
  5. Add Hemp Hearts to Topping: Measure out ⅔ cup of the crumble mixture into a small bowl. Stir in hemp hearts to incorporate them evenly for the topping.
  6. Make Crust: Press the remaining crumble mixture evenly into the bottom of the prepared baking dish using your hands to form an even crust layer.
  7. Pour Filling: Spread the thickened blueberry filling evenly over the crust layer in the dish.
  8. Add Topping: Sprinkle the oat crumble and hemp heart mixture evenly over the blueberry filling to form a crumbly top layer.
  9. Bake: Place in the preheated oven and bake for 35-40 minutes, until the topping is golden brown and the blueberry filling is bubbling and sticking to the pan edges.
  10. Cool: Remove from oven and transfer to a wire rack to cool completely. Allowing the bars to cool fully is essential to set the filling and prevent the bars from falling apart when cut.
  11. Serve: Once cooled, cut the bars into 12 squares. Enjoy immediately or chill in the refrigerator for a firmer texture and enhanced flavor.

Notes

  • Use fresh or frozen blueberries based on availability; frozen does not require thawing.
  • Coconut oil should be solid or at room temperature to create the perfect crumble texture.
  • Let bars cool fully before cutting to ensure clean slices that hold together properly.
  • Chilling the bars enhances the flavor and makes them easier to handle.
  • Arrowroot powder can be substituted with cornstarch with similar thickening results.
  • For a gluten-free version, ensure oat flour and rolled oats are certified gluten-free.
