A question about a recipe: Faulknerian Family Spice Cake, with Caramel Icing

I have a question about step 2 on the recipe "Faulknerian Family Spice Cake, with Caramel Icing" from ENunn. It says:

"Sift together dry ingredients, twice. Add dry mixture to creamed mixture, alternating with the milk. Add vanilla. Bake in a greased floured tube pan at 325 for 1 hour and 15 minutes, or until cake tests for doneness. Serve with caramel icing. "
