1/2 c. butter
1/4 c. sour cream
3/4 c. sugar
3 eggs
3 tsp. baking powder
3 c. flour
1/2 tsp. vanilla
1/2 tsp. salt

Mix all above. Refrigerate overnight or 3 hours. Shape while cool into small balls. Bake 375 degrees for 10-12 minutes. Take out of oven and cut each ball into halves, put jam (I use raspberry) in center and put top on. Cool and frost with vanilla frosting.
