Watergate Cake brings together pistachio, coconut, and pudding in a delicious layer cake! A light whipped frosting and pecans on top make it hard to stop at just one slice.


For the cake:

  • 1 box (18.25 ounce) white cake mix
  • 1 cup vegetable oil
  • 1 package (3 ounce) instant pistachio pudding mix
  • 1 cup lemon lime soda
  • 3 large eggs
  • ½ cup chopped pecans (toasted optional)
  • ½ cup sweetened, shredded coconut

For the Frosting

  • 1 ½ cups milk
  • 1 package (3 ounce) instant pistachio pudding
  • 8 ounce Cool Whip, thawed
  • ½ cup chopped pecans (toasted optional)
  • ½ cup sweetened, shredded coconut


  1. In large mixer bowl at medium speed, add cake mix, oil, pudding, eggs, and soda. Fold in chopped pecans and coconut.
  2. Pour into greased & floured 9-inch round baking pans and bake in a 350 degree oven for 35-40 minutes. Cool completely on wire rack.
  3. For the frosting, combine pudding mix & milk until slightly thickened (about 2 minutes). Slowly, fold in the Cool Whip until combined. Spread on first layer of cake. Top with second cake layer and cover cake completely in frosting.
  4. Press pecans and coconut into cake and refrigerate two hours or more. Serve cold!


  • Cake Mix- can't find the 18oz size? This works with 15 oz too.
  • Cool Whip. The original recipe called for Dream Whip. If desired, use 2 envelopes with milk. Beat until fluffly, then add in pudding mix.
  • Refrigerate. Keep Watergate Cake chilled for best results. You can also freeze this cake by wrapping individual slices in a plastic wrap, then sliding them into a freezer bag.
  • Toasted coconut variation. Adding coconut to the cake adds so much moisture. But, some people don't like it ON TOP of the cake. If that's you, try toasting the coconut for a sweet candy crunch instead.
