Preheat oven to 400 degrees F. In a bowl, mix egg, milk, butter and sugar. Slowly stir in flour. Fold in the green onions, bacon, Swiss cheese and 1/4 cup Cheddar cheese. Fill muffin compartments 1/3 full.* Place one cube of Jalapeno Jack cheese in middle of each muffin compartment on top of batter. Continue to fill muffin compartments with batter until 2/3 full. Top with remaining Cheddar cheese. Bake muffins for 15 to 20 minutes or until golden brown. Let stand 5 minutes before removing from pan. Serve warm.

*If necessary, grease before filling.
