Cook sausages in a large skillet over medium 12-15 minutes, turning occasionally, until browned and cooked through.
Meanwhile, whisk flour, sugar, baking powder, and salt in a large bowl.
Beat eggs in a separate bowl; whisk in milk and melted butter.
Stir wet ingredients into dry just until combined; leave lumps and do not overmix.
Heat a griddle or large non-stick pan over medium; lightly grease with butter or cooking spray.
Pour 1/4 cup batter per pancake; cook 2-3 minutes until bubbles form and edges set. Flip; cook another 1-2 minutes until golden brown.
Serve pancakes stacked with sausages alongside and maple syrup for drizzling.
