Preheat oven to 350 degrees F and grease donut pan thoroughly. I used non-stick cooking spray which worked well. In a medium sized bowl, mix the ingredients from flour through ground cloves.
Whisk together to blend. Using an electric mixer, blend butter and brown sugar together until fluffy. Add the egg and vanilla and continue beating until well blended.
Turn the mixer to low and alternately add sour cream and flour mixture. Mix until just combined. Batter will be thick. Fill each cavity of the donut pan almost full.
