Ingredients
  

Blueberry Filling

  • 2 cups Frozen blueberries defrosted
  • 2 teaspoon Corn starch
  • 1 tablespoon Lemon juice
  • ¼ cup Splenda (or any white granulated sugar/sweetener)

Bottom Layer and Top Crumble

  • 1 ¼ cup Flour
  • ½ cup Splenda (or any white granulated sugar/sweetener)
  • ¼ teaspoon Baking powder
  • ½ cup Plain greek yogurt
  • 1 large Egg
  • 1 tablespoon Brown sugar
  • ½ cup Quick oats

Instructions
 

  • Preheat oven to 375 F and grease an 8x8 square baking dish. Line with parchement paper making a 3 inch overhang.

For the Bottom Layer

  • In a medium sized bowl add the sweetener and then sift in the flour and baking powder. Mix together with a fork.
  • Cut in the greek yogurt and egg using your fork until the mixture looks crumbly. Separate ¾ of mixture into the greased/lined baking dish and pack into an even layer with your hands. Set remaining ¼ mixture aside.

For the Blueberry Filling

  • In a medium bowl add the blueberries, corn starch, lemon juice and sugar then mix well. Pour into even layer over the bottom layer in the baking dish.

For Oat Crumble

  • Return to the remaining crumbly mixture and add in the brown sugar and oats. Mix everything together again using a fork. Mixture should remain relatively crumbly. Crumble liberally over the blueberry layer using your hands.
  • Bake in preheated oven for 45 minutes. Remove from oven and let cool completely in fridge (approx 2-3 hours) before cutting and serving. Use the 3 inch overhang to remove the bars from the baking dish and then cut.

Notes

You can use regular granulated sugar in place of the Splenda; however, this will significantly increase the calories in the bars.
