While the cookies bake and then cool, make the buttercream frosting. Beat softened butter, vanilla and brown sugar. Combine sugar, salt and flour then combine it with the butter/sugar. Beat until smooth. Add just enough cream to make a piping consistency.

You can heat treat the flour – sprinkle ½ cup flour on a baking sheet and bake at 350° for 10 minutes.
