  • oven


  • 2 cups frozen blueberries
  • 1/4 cup orange juice
  • 1 tbsp tapioca flour or cornstarch mixed with 3 tbsp. water
  • 1 tsp vanilla powder or essence
  • 1/2 cup maple syrup or other liquid sweetener of your choice
  • 3 cups oats, divided in two
  • 3/4 cup unsweetened apple sauce
  • 1/4 cup water
  • 1/2 tsp cinnamon
  • 2 tsp baking powder
  • 1/4 tsp salt
  • 1/4 cup extra oats to add to the topping
  • 1/4 cup finely chopped nuts
  • 1 tbsp coconut sugar or maple syrup


  • Heat the oven to 375F / 180C
  • Place the blueberries and orange juice in a small pan and bring to a boil. Add in the tapioca mixture and let it thicken for a minute. Remove from heat.
  • Blend half of the oats into a flour. Add in the remaining oats, baking powder, salt, cinnamon. Stir well. Add in the apple sauce, maple syrup and water and form a dough. 
  • Press 2/3 of the dough into a lined baking sheet, about 8x8 inch. Scoop on the blueberries. 
  • Mix the extra oats, coconut sugar ( optional ) and chopped nuts to the remaining dough. Tear off small pieces and add them on the blueberry layer. It should cover about 90% of the surface. 
  • Bake for 30 minutes or until golden. Serve warm, scoop with a big spoon, or let it cool and slice into squares. Keep in the fridge for 3 to 4 days. 


You can add some stevia or a little more maple syrup if you prefer the berries to be sweeter.
