Recipe: Pineapple Cake

I found this in my files, but have not tried it. It sounds similar to the one you described.

4 Large egg whites, reserving 2

2 c Sugar

3 T Flour

1 (20 oz)can crushed pineapple

using 1 1/3 cup water, omitting oil and using 2 egg whites
in place of eggs. Pour batter into cake pans and bake; cool
completely. Beat 2 remaining egg whites with 1/2 c sugar.
In medium saucepan combine remaining 1 1/2 cups sugar
