    I have been making this for years, but I do not make the frosting. I make a drizzle of powdered sugar, milk & almond flavoring. That is delicious & everyone scraps up any that drops onto the cake! If you use sugar free pudding it cuts down on the calories . I use a white cake mix with the whole egg, Sprite zero for the soda. Very moist & flavorful!

    this has been in our family since it was published in the Southern Living Magazine in 1970. Yes, it was called a Watergate Cake and I still have the OLD worn out recipe in my files. Still my kids favorite birthday cake after 45 years. They call it the green cake. I make it into a 3 layer cake and put the filling between the layers. I add coconut and pecans to the cake and crushed pineapple and pecans to the Cool Whip pistachio pudding filling. As well as a favorite bday cake, i also make it for easter and st patricks day. DELICIOUS.

    My aunt made this cake for us over Christmas. It is THE BEST cake I have ever had. Light, fluffy. delicious! We even made a sugar free version with a sugar free cake mix, sugar free cool whip, and sugar free pudding. A delightful treat!

    Made this cake for family Christmas. I used half of the walnuts called for. However, the cake was a little on the dry side. Used a moist white cake mix.

    I've made this recipe for years, minus the walnuts and put in chocolate chips instead. It was my husbands favorite and he'd ask for it every birthday! It makes for a good St. Patty's Day dessert too. I added neon green food coloring to mine. :-) Absolutely delicious!
