Beat in:
On low speed, add slowly, mixing only until thoroughly blended:
Scrape the batter into the pan(s). Bake until a toothpick inserted into the center comes out clean, about 1 hour for loaf pans, about 15 minutes longer for a tube pan.
Let loaves cool in the pans on a rack for 10 minutes, a tube cake for 15 minutes. Turn the cake(s) out of the pan(s). Turn loaves right side up to cool. Let a tube cake cool upside down.
