Prepare a baking dish with cooking spray.
Preheat the baking dish in the oven.
Brown the sausage in a skillet over medium heat; drain.
Mix the flour, white sugar, brown sugar, baking powder, and salt in a large bowl.
Stir in the eggs, milk, vegetable oil, and vanilla to form a batter.
Add the sausage and stir. Pour into the preheated baking dish.
Bake until a toothpick inserted into the center of the dish comes out clean, about 25 minutes.
Allow to cool 10 minutes before cutting to serve.
Pour warm maple syrup over and eat.
