Heat oven to 375 degrees. Line the bottom of a 9-inch springform pan with parchment paper, coating the parchment paper and insides of the pan with cooking spray. Set aside.
In a small bowl, cut together pancake mix, brown sugar, ground cinnamon, fine sea salt, maple syrup and cold butter. Mixture will be crumbly and resemble brown sugar when complete. Set aside.
In a large mixing bowl, combine pancake mix, whole milk, maple syrup and lightly beaten egg.
Transfer coffee cake batter to prepared springform pan. Top with streusel and using a knife or toothpick, swirl streusel mixture into cake batter.
Bake for 30-35 minutes, or until it passes a toothpick test.
Remove and allow to cool for 15-20 minutes before removing from pan and serving warm.
