In a large skillet, cook sausage links until done (internal temperature of 160°). Remove and place on plate lined with paper towels. Set aside.
In a large bowl, whisk flour, sugar, baking powder and salt together until combined.
In a small bowl, add milk, egg, vanilla, and slightly melted butter. Mix until well combined.
Pour the wet ingredients into the dry mixture and stir until combined (batter will be slightly lumpy).
Add maple syrup and stir to combine.
Preheat oil in a tall, slender saucepan over medium high heat.
Pour pancake batter into a tall cup.
Insert wooden skewers into the end of cooked sausage links and one-by-one dip them into the pancake batter to coat.
Carefully place the pancake batter coated sausage links into the hot oil and cook until the batter is golden brown in color (45 seconds to one minute).
Remove from oil and let cool for a minute or two before serving.
