Anyway, I absolutely love this cake. And I'm not a huge cake fan. There's something about pistachio pudding in a cake that makes me giggle.
So, without further ado -
Watergate Cake*
1 white cake mix
3 eggs
1 pkg. instant pistachio pudding (dry)
1 cup oil (or do 1/2 oil, 1/2 applesauce for less fat)
1 cup 7-Up
1/2 cup pecans, chopped
1/2 cup flaked coconut
Preheat oven to 350º F.
Prepare a 9x13-inch pan according to instructions on the cake mix box. Mix ingredients in order given, making sure to combine everything well. Pour the batter into the pan. Bake for 30-40 minutes until a toothpick inserted into the center comes out clean. Cool completely before frosting.
Frosting:
1 small container whipped topping
1/2 cup pecans, chopped
1 pkg. (3 oz.) instant pistachio pudding (dry)
In a medium bowl, dump in the whipped topping and fold in the chopped nuts and dry pudding mix until well combined. Use to frost the cooled cake. Keep frosted cake in the refrigerator.
