Blueberry Filling

  • 1/2 cup white sugar
  • 3 tbsp lemon juice
  • 2 cups frozen blueberries

Instructions
 

  • Preheat the oven to 350°F and lightly grease and line a square pan with foil.
  • In a bowl, add brown sugar, white sugar, flour, and quick oats. Whisk until mixed.
    1/2 cup white sugar, 1/4 cup brown sugar, 1 cup flour, 3/4 cup quick oats
  • Add in egg yolk and melted butter and continue on mixing using a wooden spoon or your hands. It will turn into a crumbly form.
    1 egg yolk, 1/2 cup butter
  • Set aside 1 cup of the dough. This will be for the topping.
  • Transfer the rest of the dough into the pan and press down firmly with your hands or the bottom of a glass. Ensure the entire pan is covered.
  • In a separate bowl, mix together the blueberries, white sugar, and lemon juice with a spoon.
    1/2 cup white sugar, 3 tbsp lemon juice, 2 cups frozen blueberries
  • Scoop the filling onto the base of the bars. Evenly distribute.
  • Add the remaining crumble mixture on top over the berry layer.
  • Bake in preheated oven for 30-35 minutes or until the top begins to become a golden brown colour.
  • Allow to cool completely before slicing. You may speed up this process by placing it into the fridge.
  • Store cooled bars in an airtight container in refrigerator.
  • Enjoy!
