Cream Cake

Preheat oven to 350 degrees F (175 degrees C). Grease one 9x9 inch square pan.
Beat eggs in a small bowl until very thick. Add the sugar and the vanilla, beating well.
Combine the flour, baking powder, and salt. In three parts add the flour mixture alternately with the whipping cream to the egg mixture, beginning and ending with the flour mixture. Pour the batter into the prepared pan.
Bake at 350 degrees F (175 degrees C) for 30 to 40 minutes or until a toothpick inserted near the center comes out clean.
