Heat oven to 350 degrees F. Grease and flour 13x9x2-inch pan.
Beat all ingredients on low speed for 30 seconds. Beat on high 3 minutes. Pour into pan. Bake for 40-45 minutes or until toothpick inserted in center comes out clean. Cool 10 minutes, remove from pan and cool on wire rack.
Frosting:
Mix 4 cups of sugar with water, one cup at a time, beating after each addition at low speed. Alternately add shortening and remainder of sugar. Add salt and flavorings; beat at low speed until smooth. It is best to use a heavy duty mixer. To avoid powder sugar from going all over cover your bowl with a towel while mixing. Mix in orange color paste or 2 drops of yellow and 1 drop of red food coloring and mix.
Spread frosting on top and sides of cake. Sprinkle autumn colored candies on top.
