Preheat your oven to 375°F (190°C).
In a skillet, cook the sausage over medium heat until browned, breaking it into crumbles as it cooks.
In a large mixing bowl, combine pancake mix, eggs, milk, maple syrup, vanilla extract, baking powder, and cinnamon until just combined.
Spread the cooked sausage evenly in a greased 9x13-inch baking dish.
Pour the pancake batter over the sausage in the baking dish, spreading it evenly.
Drizzle additional maple syrup over the top for a sweet glaze.
Bake for 25-30 minutes or until the pancake bake is puffed and golden brown.
Let cool for a few minutes before slicing and serving.
