Grease your pie plate and preheat the oven to 350 degrees Fahrenheit.
Combine the ingredients for the blueberry filling in a large mixing bowl. Stir to combine and pour into the prepared pie plate.
In a small/medium mixing bowl, mix together the ingredients for the crumble topping.
Pour the crumble topping on top of the blueberry filling in the pie plate. Start in the middle of the plate and spread outwards to reach the edges.
Bake for 40 minutes or until the blueberries begin to bubble.
Serve with ice cream or homemade whipped cream. Enjoy!
