In a large skillet, cook the sausage patties over medium-high heat until fully cooked and no longer pink. Drain the excess grease on a paper towel-lined plate and set aside.

Sift together the all-purpose flour, baking powder, salt, and sugar in a large mixing bowl.

In a separate small bowl, whisk together the milk, egg, vanilla extract, melted butter, and maple syrup until fully combined.

Make a well in the center of the dry ingredients and pour in the wet mixture. Stir until the batter is smooth and free of lumps.

Preheat a griddle or frying pan over medium-high heat and spray with a non-stick cooking spray.

Dip each cooked sausage patty into the pancake batter, ensuring it's fully coated.

Place the battered sausage onto the preheated griddle or skillet. Cook until the batter bubbles, then flip and cook the other side until golden brown. Repeat until all the sausages are cooked.

Serve warm with butter and maple syrup.
