Ingredients
  

For the crust

  • 1 ½ cup (190g) all-purpose flour
  • 2 cups (200g) rolled oats
  • 3/4 cup (150g) sugar
  • 1 tsp (4g) baking powder
  • 1/2 tsp (2g) salt
  • 1 cup (226g) unsalted butter , room temperature
  • 2 tsp (10g) vanilla extract

Blueberry Filling

  • 20 oz (600g) fresh blueberries
  • 1/4 cup ¼ cup (50g) sugar
  • 2 tbsp (16g) cornstarch
  • juice from a lemon

Instructions
 

Prepare the crust.

  • Preheat oven to 350F (180C). Slightly grease a 9x13 inch (23x33cm) pan and line with parchment paper, in such a way that some edges are longer to make it easy to lift it up once it's set.
  • In a bowl, combine flour, oats, sugar, baking powder and salt. Add butter and vanilla and stir until combined and crumbly.
  • Press ⅔ of the crumb mixture into the bottom of the pan.

Prepare the blueberry filling.

  • Place the blueberries into a bowl. Add sugar, lemon juice and cornstarch and toss to coat. Spread the blueberries over the crust.
  • Sprinkle the reserved ⅓ crumb mixture over the blueberries.
  • Bake for 40- 50 minutes or until lightly browned.
  • Cool completely before cutting into bars.
  • Keep the leftovers in an airtight container at room temperature or refrigerate for up to 4 days.
