Faye's Quick and Easy Lemon Cake

1 box Duncan Hines deluxe lemon cake mix* 

1 c. cold water

1 1/4 c. confectioners sugar

1 T. lemon juice

1 t. finely grated lemon peel

1 pkg. jello lemon instant pudding mix

4 eggs

3/4 c. oil

1/4 c. softened butter

3 T. cream

Place pudding mix in bowl. Add cold water. Blend until it starts to thicken. Add cake mix, eggs, and oil. Beat on medium speed for 5 minutes. Pour into greased. paper lined tube pan. Bake 1 hour at 350. Cool in pan 10 minutes. Turn out onto wire rack to cool. Combine remaining ingredients. Beat until smooth. Add more sugar if necessary to thicken. (This was Faye's husband's favorite cake).

*Cake mixes used to be 18 oz. but now they are 15 oz. Add 2/3 c. yellow or white cake mix to make up the difference.
