CAKE PREPARATION:Beat eggs and sugar until light and fluffy; add oil and beat until incorporated. Add dry ingredients, and beat on medium speed until incorporated. Add diced apples and beat until apples are crushed into small pieces.
Grease a 9 x 13 inch ceramic or metal pan, and bake at 350˚F for 45 minutes or until a toothpick comes out clean.
FOR A LAYER CAKE: Bake in two 9-inch round pans, greased and floured, at 350˚F for 40 minutes or until a toothpick comes out clean. Double the frosting recipe and ice the cake once cooled.
FROSTING PREPARATION: Beat until smooth. Spread on top of cooled cake (a double-layer may be best!). Enjoy this scrumptious cake!
