I loved those too! I have a recipe that's quite similar but it's better the next day. Too fluffy the first day. It looks like you have a couple of recipes already but here is mine.....
Tomato Soup Cake
3/4 cup shortening
1 1/4 cup sugar
2 eggs
1 10-oz can Heinz Con. Tomato Soup
3/4 cup water
1 tsp. baking soda
3 cups all-purpose flour
1 tbsp. baking powder
1 tsp. cinnamon
1 tsp. nutmeg
1 tsp. cloves
3/4 cup raisins to be added to the batter before it goes into the pan.
Cream shortening and sugar well. Add eggs. Combine soup, water, baking soda. Sift together flour, baking powder and spices. Add soup mixture and sifted dry ingredients alternatly, stirring after each addition. Pour into greased 9 X 9 X 2 inch pan and bake at 350º for 55 minutes. When cool frost with cream cheese frosting.
