Buttermilk Cookies with Caramel Frosting

*NOTE: Dough needs to be refrigerated overnight! Hence, the long prep time. These are really easy to make.*

Cream sugar and butter; add vanilla and eggs and beat well. Dissolve baking soda in buttermilk. Sift together flour and baking powder. Add buttermilk and flour mixture alternately to the creamed butter mixture. Combine thoroughly then store covered in refrigerator overnight.

Drop dough onto cookie sheets and bake at 350 degrees F for 12 minutes. Remove from the sheets onto cooling rack to cool. Ice cookies once they are cooled.

For the frosting:
Melt butter over low heat in a saucepan. Blend in brown sugar and salt. Cook this on low heat for 2 minutes stirring constantly. Add milk and remove from heat. Stir in powdered sugar and vanilla and combine thoroughly. Let cool and then ice cookies.

I think these are best eaten on the second day. They seem to get just a tad bit softer.
