Mix all cake ingredients together at medium speed in a mixer until well blended. Pour into 3 prepared 23 cm cake pans. Bake at 180ÂșC F for approximately 20 minutes. FROSTING: Beat first three ingredients together until fluffy. Fold in 1.5 cups pecans, reserving half cup to decorate the top of the cake. Frost cooled cake layers, then decorate the top. W.S. didn't say, but walnuts would also work fine. Chill cake one hour or more before serving. ----
