Bake the biscuits according to the package. It is best if you can bake them the night before so they are not too fresh and soft.
Spray a 9x13 casserole dish with some nonstick cooking spray.
Cut each of the biscuits into 12 pieces, and spread the pieces evenly over the bottom of the dish.
Spread the fresh blueberries on top of the biscuit pieces.
In a bowl or large measuring cup, whisk together the eggs, milk, sugar free maple syrup, vanilla extract, and cinnamon.
Pour the mixture evenly over the biscuits and blueberries. Cover and let it sit in the fridge for 30 min - 1 hour.
In a small bowl mix together the sugar, all purpose flour, and melted butter until it forms a crumb. Sprinkle it evenly over the top of the bake.
Heat the oven to 350F and bake it for 40 minutes.
Let it cool slightly, and enjoy!
