Cream together shortening and milk for about 3 minutes, (it will look like small curd cottage cheese.) Add in vanilla.

In a separate bowl combine flour, sugar, baking powder and salt. Add flour, one third at a time to the milk mixture, blending well after each addition.

Lastly, add in egg whites, beating just until all combined.

Pour batter into a greased and floured (do not use a spray) 10 inch cast iron skillet.

Bake in a preheated 350 degree oven for 40-45 minutes, using a toothpick inserted in the center to test for doneness. (last picture is with caramel sauce on top.)
