What is Watergate Cake?

Watergate Cake is a light and fluffy dessert that originated in the United States during the 1970s, around the time of the Watergate scandal—hence its intriguing name!

This cake is typically made with pistachio pudding mix, which gives it a lovely green hue and a slightly nutty flavor.

And as mentioned, it’s often topped with a whipped frosting, sometimes made with more pistachio pudding or Cool Whip.

Despite its political name, Watergate Cake has nothing to do with the scandal itself. In fact, nobody really knows the true origins.

But its delicious flavor has made it a nostalgic favorite at potlucks and family gatherings!

    But before you start, check out these tips:

    • Soda choice. Use a lemon-lime soda like 7UP or Sprite to give the cake its signature flavor and moisture. Or try ginger ale for a lightly spiced finish.
    • Add-ins are key. Don’t skip the chopped pecans and shredded coconut, as they add texture and flavor to the cake.
    • Chill the cake. Chill the cake for at least 30 minutes before slicing and serving. This allows the frosting to set and the flavors to meld together.
    • Freezing tip. For a moister cake, freeze it after baking and cooling, then frost it just before serving.
    • Variations. You can add chopped walnuts, pineapple, or chocolate chips to the batter. You can also use a yellow cake mix instead of a white one, but the color will be less vibrant.
    • Topping ideas. Sprinkle over some mini marshmallows, pineapple tidbits, or chopped maraschino cherries for color.

    How to Store

    Believe it or not, this cake tastes best the day after it’s made right out of the fridge.

    So it’s perfect as a make-ahead dessert!

    To Store: Keep the Watergate Cake in an airtight container in the fridge for up to 5 days.

    To Freeze: Wrap the unfrosted cake tightly in plastic wrap, then aluminum foil, and store it in the freezer for up to 3 months. Thaw in the refrigerator overnight before frosting and serving.
