The ingredients are simple and you likely have most of them on hand. The recipe is pretty straight forward as well and it's in printable format at the bottom of this post!
1 ½cupsall purpose flour
1 ½cupsquick oats
¾cupcold unsalted butter cubed
3cupsfresh or frozen blueberries
Preheat oven to 375. Grease a 9 x 13 metal baking pan.
Put first 7 ingredients in the food processor and process until crumbly not a ball. Reserve 2 cups for topping.
Press remaining crumb mixture into pan. Set aside.
Put rest of ingredients into a small sauce pan and bring to a boil for 2-3 minutes until thick. It will look like blueberry jam. Spread over crust. Put on reserved topping and bake 25-30 minutes or until golden. Cool completely and enjoy!
