Preheat the oven to 375 degrees. Grease and dust with flour a single 9-inch round cake pan for a single layer cake. Dust two if you are doubling the recipe for a layer cake.
1. Cream the sugar, salt, and shortening together. Add the egg and beat until light and fluffy. Add the vanilla.
2. In another bowl, mix the flour and baking powder together.
3. Add about one-third of the dry ingredients to the creamed mixture and mix briefly. Add about one-third of the milk and mix. Continue twice more with the remaining flour and milk. Do not over mix. Scrape the batter into the pan.
4. Bake for 25 to 30 minutes or until the cake tests done with a toothpick.
Let the cake rest in the pan for about five minutes and then remove it to a wire rack to continue cooling.
