Spray the plates of the waffle iron with cooking spray or brush with oil. Spoon about 45 ml (3 tbsp) of batter onto each lower plate and spread evenly. Place four sausage skewers over the batter, spacing them slightly apart. Cover with another 45 ml (3 tbsp) of batter on each section and spread evenly. Cook for 4 to 6 minutes, until golden. Remove from the waffle iron, then cut between each skewer. Repeat with the remaining batter and sausage skewers.
