Beat margarine, Equal, and spreadable fruit together until combined and creamy.
Mix together the egg, vanilla, and milk. Add to the margarine mixture alternately with the self-rising flour. (The mixture will be thick.) Spoon mixture into a greased and lined 8-inch round cake pan.
Peel and core apple; cut into slices. Dip slices into lemon juice. Place decoratively on top of cake mixture.
Bake in preheated 350 degree oven for 30 minutes, or until toothpick comes out clean. Turn onto a wire rack with apple on top. Sprinkle with cinnamon and additional Equal while cake is still warm.
