01 -  Preheat oven to 375°F (190°C) and lightly grease a 12-cup muffin tin. 
 02 -  Brush each wonton wrapper with melted butter. Press wrappers into muffin cups to create cup shapes. Bake for 7 to 8 minutes until lightly golden. Remove from oven, keeping the oven on. 
 03 -  Boil elbow macaroni according to package instructions until al dente, then drain and set aside. 
 04 -  Warm 1 tablespoon butter in a saucepan over medium heat. Stir in flour and cook for 1 minute to form a roux. Gradually whisk in milk; cook, stirring, until slightly thickened, approximately 2 to 3 minutes. 
 05 -  Lower the heat and add shredded cheddar, grated Parmesan, salt, black pepper, and cayenne if using. Stir until cheese is fully melted and sauce is smooth. 
 06 -  Fold drained macaroni into the cheese sauce, mixing thoroughly. 
 07 -  Spoon macaroni and cheese mixture evenly into pre-baked wonton cups. 
 08 -  In a bowl, mix panko breadcrumbs, 1 tablespoon melted butter, and 2 tablespoons grated Parmesan. Sprinkle breadcrumb mixture over each filled cup. 
 09 -  Return muffin tin to oven and bake for 10 to 12 minutes, until tops are golden and crisp. 
 10 -  Let cool slightly, then garnish with chopped chives if desired. Serve warm.
