Heat oven to 375°F. Line 13x9-inch pan with foil. Arrange drummettes in single layer in foil-lined pan.
In small microwave-safe bowl, combine all remaining ingredients; mix well. Microwave on HIGH for 1 minute or until sugar is dissolved, stirring once halfway through cooking. Pour sauce over drummettes to cover.
Bake at 375°F. for 30 minutes. Turn drummettes over; bake an additional 20 to 30 minutes or until drummettes are glazed, fork-tender and no longer pink next to bone.
