Preheat oven to 375 degrees.
Grease a 24-cup mini-muffin pan. The tiny mini-muffin pan openings are a real challenge to grease using butter or margarine. This is definitely a time to use one of the widely available vegetable sprays.
In a large bowl whisk together the flour and baking powder. In a separate bowl mix together the buttermilk and the egg, and then add them to the flour mixture. Stir until just blended.
Add the grated cheese and the chopped chives. It is best if you let the mixture rest for 10-15 minutes before baking. Lie down. Put up your feet. Have a glass of white wine.
Divide the batter among the greased mini-muffin cups. Bake until puffed and golden about 20 minutes.
