Hi Reine;
This recipe is from a 1969 Betty Crocker cookbook. The identical recipe is in a much newer edition under the title "Yellow Cake". So I am assuming this is the one you are looking for,
STARLIGHT CAKE
2 cups all purpose flour
11/2 cups sugar
31/2 tsps. baking powder
1 tsp. salt
1/2 cup shortening (half margarine or butter, softened, if desired)
1 cup milk
1 tsp. vanilla
3 eggs
Heat oven to 350, Grease and flour 2 round layer pans or a 9x13 pan. Beat all ingredients in large mixer bowl on low speed, scraping bowl constantly, 30 seconds.
Beat on high speed, scraping bowl frequently, 3 minutes. Pour into pan(s).
Bake until wooden pick inserted in center comes out clean, (9x13-40 to 45 minutes) (layers-30 to 35 minutes. Frost as desired.
Let me know if this is the right recipe.
