In a bowl, mix together flour, sugar, baking powder, and salt.

In another bowl, whisk together milk, egg, and melted butter.

Combine the wet ingredients with the dry ingredients until just blended.

Heat a griddle or skillet over medium heat and pour batter to form pancakes.

Cook until bubbles form on the surface, then flip and cook until golden brown.

In the last few minutes of cooking, place a slice of cheese and a sausage link on half of the pancakes, drizzle with maple syrup.

Top with remaining pancakes to form a sandwich.
