Blueberry Crumble Bars

If you don’t have oat flour pour quick or old-fashioned oats into a blender and blend until you get a powder.

To keep the bars fresh, place them in the fridge otherwise they will tend to soften.

  • Start by preparing the blueberries. Pour the frozen blueberries into a saucepan over medium heat.

  • Preheat your oven to 350ºF.
  • In a large bowl, combine the oat flour, quick oats, salt, coconut sugar, vanilla extract and cubed butter. Mix with your hands. The mixture should be homogeneous and like crumble.
  • Line a 9-inch square pan with parchment paper. Pour 2/3 of the crumble mixture in the pan. With your hands flatten the dough in the bottom. It must be flattened evenly and at the same level.
  • Pour the cooked blueberries and spread throughout the pan on top of the flattened dough.
  • Finally, add the last level with the crumble on top. This time, it should not be flattened but crumbled.
