Preheat oven to 350 degrees F and grease a 9x13 inch baking dish with cooking spray. Set aside.
Cobbler Topping
Mix melted butter, brown sugar, vanilla, almond extract, flour, baking powder, and salt together in a medium sized bowl until well combined. Set aside.
Cobbler Filling
Gently toss blueberries, brown sugar, cinnamon, cornstarch, lemon juice, and almond extract together in a large bowl until well combined.
Pour into prepared baking dish and spread out into an even layer.
Use a small cookie scoop to scoop the cobbler topping over the filling, then use your hands to gently press down and spread out the topping.
Sprinkle turbinado sugar over the top.
Bake in preheated oven for 45-60 mins or until the filling has thickened and the topping has cooked.
Remove from the oven and cool for 20 minutes in the pan before scooping and serving with vanilla ice cream.
