Adapted by a friend from Baker Bettie.
5 T. butter
1/2 c. brown sugar
1/2 c. sour cream
1 t. vanilla
2 t. baking powder
1 1/2 c. flour
Cinnamon Sugar Topping:
1/4 c melted butter
1/4 c. sugar mixed with 1/2 t. cinnamon
Cream butter and sugar, stir in remaining dry ingredients. Form balls and bake at 325 for 8-10 minutes (I THINK I had to bake them quite a bit longer).
Cool slightly, then dip in butter and then sugar mixture. Yum...
