Preheat oven to 350 degrees Fahrenheit. Grease two loaf pans and set aside.
In a large bowl, beat together margarine and sugar. Add vanilla and mix. Add eggs one at a time and beat in between each addition. Add sifted flour, baking powder, and salt. Beat until combined.
Add walnuts and mix with a large spoon. Pour batter into loaf pans. Bake for 35-40 minutes.
Let the cakes cool, then place in freezer.
