Seven-layer Cake

“It takes practice, but everyone loves Seven-layer Cake.” Delectable as it is impressive-
¾ cup shortening
3 ⅓ cups sifted cake flour
2 ¼ cups sugar
4 ½ teaspoons baking powder
1 ½ teaspoons salt
********************
1 ½ cups milk
3 eggs
2 teaspoons vanilla
Stir shortening just to soften. Sift in dry ingredients. Add 1 cup of the milk, mix until all flour is dampened. Then beat vigorously 2 min. Add remaining milk, the eggs, and vanilla. Beat vigorously 2 mins. Longer.. Pour about 2 cups of the batter into a lightly greased and floured 9x1½ round pan. Tip pan so batter runs over bottom. Invert pan over cooky sheet, allowing as much batter to run out of the pan as will do so easily. Turn pan right side up, scrape down sides to prevent burning, and even out batter remaining on bottom. Repeat for other 6 layers, baking as many at a time as you have pans and oven space. *Bake in hot oven (400F) about 8 minutes or till done. Cool in pans 3 to 5 minutes, then invert on rack to cool thoroughly. Put layers together and frost with Chocolate Butter Frosting. *While baking first cakes, keep remaining batter in refrigerator.
