For blueberry Layer:
  • Blueberries – 2 cups
  • 1 tsp vanilla extract
  • 1/3 cup granulated sugar

INSTRUCTIONS:

Make the Blueberry Layer:

Whisk well, and add this to blueberry sauce. Boil for a minute and transfer the sauce into another bowl. Let it cool completely.
Making the Crust and Crumble Topping
  1. Preheat oven to 350°f/175 C°. Line an 8-inch baking pan with foil and spray with some nonstick cooking spray. Keep it aside.
  2. Add oats, flour, brown sugar, granulated sugar, salt, butter and cinnamon powder to a mixing bowl. Mix well to form crumble pieces.
  3. Transfer half of the crumble mixture to the to prepared baking tray, and press well.
  4. Evenly distribute cooled blueberry sauce over the crust.
  5. Add remaining crumble mixture to the top, and press well again.
Baking Bars:
  1. Bake for 50-55 minutes until edges are set. Crumble topping should appear lightly golden brown at this point.
  2. Let the crumble cool completely before slicing into bars. Enjoy!
  3. To slice the bars, lift them out of the pan, and slice with a sharp knife.
  4. Serve them cold, at room temperature, or warm them up in the microwave.
  5. Optionally, add a scoop of ice cream on top of each.

NOTES:

  1. Only use old fashioned oats or large flakes oats. Don’t use quick cook or instant or else the mixture will become too dry and you won't get crumbly texture.
  2. I am using fresh blueberries for blueberry layer, but you can also use frozen blueberries. You don't need to thaw frozen blueberries.
  3. Blueberry Oatmeal Bars stay fresh in airtight at room temperature for up to 1 week. You can also refrigerate them for up to 10 days.
