Preheat oven to 350°F. Grease muffin cups.

In a large bowl, beat together sugar and butter until light and fluffy, about 3 minutes. Beat in egg. Beat in vanilla.
Add 1/2 flour mixture to batter and beat until just combined. Beat in 1/2 cup buttermilk, followed by remaining flour. Beat in final 1/2 cup buttermilk.
